1 SEISMIC RESTRAINTS Multi-Directional Bracing For Electrical Conduit, Cable Tray And Mechanical Piping Systems SYSTEMS THAT MAKE SENSE

2 INTRODUCTION INTRODUCTION What is Seismic Bracing? Seismic forces are exerted on a building and its contents during an earthquake. These forces act horizontally upon the structure itself, as well as the piping, cable trays, ductwork, and other building systems within. Typical supports for piping, trays, and other equipment are designed for the gravity, or vertical, loads but do not take into account the horizontal loading caused by earthquakes. Seismic restraints (i.e. braces) resist the horizontal forces and keep the systems in place and secure. The main purpose seismic bracing is safety- to minimize the loss life due to an earthquake. Seismic Bracing Requirements The rules and requirements for the seismic restraints are published in the model building codes: The Uniform Building Code (Inter national Conference Building Officials), National Building Code (Building Officials and Code Administrators), Standard Building Code (Southern Building Code Congress International), and the International Building Code. Each code is similar in nature, and has a chapter on structural forces which defines the level seismic force that must be used in the design seismic restraints. The amount seismic force (as determined by the building code) is given as a percent the components weight, or g-force. If the horizontal force is determined to be 50 percent the piping weight, for example, the seismic force is.5g. The seismic "g-value" can vary greatly depending on the nature the project. Critical buildings in a high seismic zone have larger g-value requirements than warehouses in zone 1. Factors that govern the seismic g-values used for design: Seismic Zone Soil Type Building Type Distance from known faults Elevation within building Anchorage Type System being braced The design pressional should use these factors and the applicable building code requirements to determine the proper g-values to be used for the project. This manual has been developed under the requirements the 2001 California Building Code, and contains seismic bracing details that can be used for seismic bracing projects up to 1.0g (ASD) or 1.4g. The brace spacing charts, required details, and rod loads must be determined for the specific g-value for the project and shall be submitted to the engineer record prior to construction. The determination the seismic force level shall also be submitted to the engineer record and to OSHPD for hospital projects in the state California prior to construction. However, the seismic force level need not be submitted to the engineer record or OSHPD if included in the original construction documents. This brochure contains charts for a variety g values, however custom charts can be created to reflect different g-values as required for the project. Contact B-Line Engineering at with your requirements. A copy the complete Seismic Restraints Manual shall be on the jobsite for the duration the project. Appropriate shop drawings signed/stamped by the architect or engineer record must also be kept. OSHPD reserves the right to review these upon request. i

4 GENERAL INFORMATION B-LINE SEISMIC RESTRAINT SYSTEMS a re designed to resist seismic loading while minimizing installation time and providing superior perf o rmance. On the following pages, several methods seismic bracing are illustrated. The choice brace design should be governed by the system requirements and location supports. Actual applications may vary and are not strictly limited to the combinations fittings and supports shown. Any changes to the depicted designs should be in accordance with standard engineering practices and be approved by OSHPD (California Office Statewide Health Planning & Development) if necessary. For additional information on hangers, channels, fittings, and hardware shown, see the latest B-Line Strut Systems Catalog or Pipe Hangers and Supports Catalog. Seismic restraints are designed to resist the horizontal seismic force in two primary directions: Transverse (perpendicular) and Longitudinal (parallel) to the run. The braces are attached to the building with a structure attachment (for concrete, steel, wood, etc.) various anchor sizes. Typically, the stronger the structure attachment, the greater the brace spacing allowed. The following steps detail how to use the brochure: Step 1: Select the bracing details for single pipe hangers or trapeze supports. Step 2: Obtain required force level (%g) from applicable code for local jurisdiction or from the structural engineer record. Example: 2001 California Building Code As defined in the 2001 California Building Code, Chapter 16A, Section 1632A, the seismic horizontal force, F p, may be calculated using the following formula: F p = a pc a I p (1 + 3 hx )W p R p h r Where: Except that: F p shall not be less than 0.7 C a I p W p and need not be more than 4 C a I p W p. F p = Seismic Force Level a p = Amplification Factor (Table 16A-O) R p = Component Response Modification Factor (Table 16A-O) = 3.0 for electrical, mechanical and plumbing equipment and associated conduit, ductwork and piping utilizing deeply embedded anchors. (Table 16A-O) = 1.5 for installations using concrete anchors with an embedment-to-diameter ratio less than 8. i.e. a 1 /2" diameter concrete anchor with an embedment less than 4" inches. 1

5 GENERAL INFORMATION I p = Importance Factor (Table 16A-K) = 1.5 for Essential facilities such as Hospitals, Fire Stations, Police Stations, Aviation Control Towers, etc. consult Table 16A-K in CBC for a detailed listing. = 1.0 for most other occupancies C a = Seismic Coefficient. This is a cumulation several factors: Zone, Soil Properties, and distance from known fault. (Table 16A-I, Table 16A-J, Table 16A-Q, Table 16A-S, and Table 16A-U) h x = Element or component attachment elevation with respect to grade. Note: h x shall not be taken less than 0.0 h r = Structure Ro Elevation with respect to grade. Special Note: This manual is based on allowable stress design (ASD), where as the seismic force level (%g or F p ) for non-structural components provided in building codes are based on strength design. For use in this manual, the seismic force levels (F p ) from the building code are converted to allowable stress design by dividing the result by 1.4. Example: If the building code yields, (F p ) = 1.4g, this value is converted to allowable stress design (ASD) as used in this catalog as follows: F p =1.4g/1.4=1.0 g Strength Design to Allowable Stress Design Conversions.21g from building code =.15g (ASD).42g from building code =.30g (ASD).63g from building code =.45g (ASD).70g from building code =.50g (ASD) 1.05g from building code =.75g (ASD) 1.40g from building code = 1.00g (ASD) Example One, Deeply Embedded Anchors: Cable tray system is installed on the 1st floor a 40-foot tall, 2-story surgical center in California. The cable tray is actually suspended from the bottom the 2nd floor, which has an elevation 20 feet above grade. Location the surgical center is in seismic zone 4 with a rock soil prile. F p = a pc a I p (1 + 3 hx )W p R p h r a p = 1.0 from Table 16A-O 2

6 GENERAL INFORMATION C a =.40Na from Table 16A-Q, which is a combination Zone and Soil prile Zone 4 =.40, from Table 16A-I Rock Soil Prile = SB, from Table 16A-J Seismic Source Type = B, for faults other than Type A & C (Table 16A-U) Near Source Factor (Na) = 1.0, for 5 km from known seismic source (Table 16A-S) I p = 1.5 from Table 16A-K, Occupancies having surgery and emergency treatment areas. R p = 3.0 from Table 16A-O for deep embedded anchors h x = 20 feet h r = 40 feet F p = (1.0)(0.40(1.0))(1.5) ( )W p = 0.50W p = 0.50g Check if value falls within limits: F p shall not be taken less than, 0.7C a I p W p = 0.7(.40)(1.5)W p =.42g F p shall not be greater than, 4.0C a I p W p = 4.0(.40)(1.5)W p = 2.4g 2.4g >.5 > 0.42g Therefore allowing the use 0.50g To convert this F p from a strength design to an Allowable Stress Design (ASD) used in this catalog divide by 1.4. F p = 0.50g = 0.36g (ASD) g is the Allowable Stress Design Seismic Load Factor determined from the 2001 California Building Code. Special Note: A table for.36g (ASD) is not available in this catalog. When seismic force levels (%g or F p ) falls between catalog table values (i.e.:.15g,.30g,.45g, etc.) the seismic force level shall be rounded up to the next highest cataloged force level. Example: If F p =.36g (ASD), then use catalog tables for.45g (ASD). Example Two, Shallow Embedded Anchors: Special Note: Installations using concrete anchors installed with an embedment length-to-diameter ratio less than 8, also referred to as shallow embedment anchors, have an adjusted Component Response Factor. The adjusted factor R p =

7 GENERAL INFORMATION Cable tray system is installed on the 1st floor a 40-foot tall, 2-story surgical center in California. The cable tray is actually suspended from the 2nd floor, which has an elevation 20 feet above grade. Location the surgical center is in seismic zone 4 with a rock soil prile, shallow embedment anchors are used for brace locations. a p = 1.0 from Table 16A-O F p = a pc a I p (1 + 3 hx )W p R p h r C a =.40Na from Table 16A-Q, which is a combination Zone and Soil prile Zone 4 =.40 from Table 16A-I Rock Soil Prile = SB from Table 16A-J Seismic Source Type = B for faults other than Type A & C (Table 16A-U) Near Source Factor (Na) = 1.0 for 5 km from known seismic source (Table 16A-S) I p = 1.5 from Table 16A-K, Occupancies having surgery and emergency treatment areas. R p = 1.5 adjusted for Shallow Embedment Anchors h x h r = 20 feet = 40 feet F p = (1.0)(0.40(1.0))(1.5) ( )W p = 1.0W p = 1.0g Check if value falls within limits: F p shall not be taken less than, 0.7C a I p W p = 0.7(.40)(1.5)W p =.42g F p shall not be greater than, 4.0C a I p W p = 4.0(.40)(1.5)W p = 2.4g 2.4g > 1.0g > 0.42g Therefore allowing the use 1.0g To convert this F p from a strength design to an Allowable Stress Design (ASD) used in this catalog divide by 1.4. F p = 1.0g = 0.71g (ASD) g is the Allowable Stress Design Seismic Load Factor determined from the 2001 California Building Code for shallow embedment anchors. Special Note: A table for.71g (ASD) is not available in this catalog. When seismic force levels (%g or F p ) falls between catalog table values (i.e.:.15g,.30g,.45g, etc.) the seismic force level shall be rounded up to the next highest cataloged force level. Example: If F p =.71g (ASD), then use catalog tables for.75g (ASD). Note: For other Code examples see Appendix 4 4

8 GENERAL INFORMATION Step 3: With required force level (%g), obtain the transverse and longitudinal brace spacing from Appendix 1 (single pipe) or Appendix 2 (trapeze hanger). The following notes shall be followed: a) B reak the length pipe into separate straight runs, which are considered to be a single straight section between any bends in the pipe except where the bend is at an fset less than the maximum fset length as defined below. Table 1 - Steel Pipe or Conduit Nominal Max. Offset Length (ft) Pipe Size 0.15g 0.3g 0.5g 0.75g 1.0g Table 2 - Copper Tubing Nominal Max. Offset Length (ft) Tubing Size 0.15g 0.3g 0.5g 0.75g 1.0g Note: The tabulated values represent pipe and tubing with moment and shear transfering joints. T h e re f o re, for use these tables pipes shall have welded, brazed, or UL Listed grooved joints. Pipe and tube sizes not listed above or joined as re q i u i red shall be limited to a maximum fset length 2 ft. Maximum Offset Length (ft.) b) Brace each straight run in the transverse direction at both ends. Where several short runs occur, see note e) on the following page. Straight Run Transverse bracing at both ends the pipe run 5

9 GENERAL INFORMATION c) Check the required spacing for transverse bracing (Appendixes 1 & 2) and compare it to the length the straight run. If the length the straight run is greater than the allowable distance for transverse bracing add transverse braces until the spacing does not exceed the allowable transverse brace distance. Straight Run Additional Transverse Braces d) Each straight run must have at least one longitudinal brace. Add longitudinal braces so that the spacing does not exceed the allowable longitudinal brace spacing in Appendixes 1 & 2. Straight Run Longitudinal Brace (Transverse brace for the adjacent run) Longitudinal Brace Longitudinal Brace (Transverse brace for the adjacent run) 24 (610mm) Max. 24 (610mm) Max. Note: A transverse brace may dually act as a longitudinal brace for an adjacent run when it is located within 24 the adjacent straight run. However, Appendixes 1 & 2 shall be reviewed to use the stronger the longitudinal or transverse brace re q u i rements, i.e. anchor and other component sizes. 6

10 GENERAL INFORMATION e) In many cases, several short runs occur one after the other. Based on previous requirements, each straight run requires a longitudinal brace when the adjacent short runs exceed the maximum fset length (ft.). When the adjacent short runs do not exceed the maximum fset length (ft.) the longitudinal braces can act as transverse braces as long as the allowable transverse brace spacing (Appendixes 1 & 2) is not exceeded. In the following layout, transverse braces are used as longitudinal braces when the straight runs are less than the maximum fset length (ft.). When a straight run exceeds the maximum fset length (ft.) additional braces are required. First Transverse Brace Second Transverse Brace Longitudinal brace Two braces may be required. Straight run exceeding the maximum fset length (ft.) Longitudinal brace Short run less than the maximum fset length (ft.) Multiple fsets can be treated as a single run when the total fset is less than the maximum fset length (ft.). Plan or Elevation 7

11 GENERAL INFORMATION f) When a flexible connection or swing joint is used, such as at a pipe drop to mechanical equipment, the pipe may cantilever at a length equal to or less than half the allowable transverse brace spacing (Appendixes 1 & 2). When greater than half the allowable transverse brace spacing, support to the floor is required as shown below. Straight Run Transverse brace at the end horizontal run Requires a flexible connection or swing joint between equipment. Allowable Transverse Brace Spacing 2 Mechanical equipment. Floor If < 6 ft. Support to Floor Is Required. Step 4: Note the structure connection type (brace anchor requirements) from the Appendix, and select the brace anchorage detail to suit (pages 23 thru 38). Step 5: Note the hanger rod load from the Appendix, and select a rod attachment to structure to suit (pages 39 thru 56). Step 6: Check if rod stiffeners are required (pages 57 & 58) to prevent the hanger rod from buckling. Seismic restraints may typically be o m i t t e d for the following conditions where flexible connectors are provided between components and the associated ductwork, piping, and conduit: 1. Fuel, medical gas, and vacuum piping less than 1 inch (25 mm) inside diameter. 2. All other piping less than 2 1 /2 inches (64 mm) diameter, or: All piping suspended by individual hangers 12 inches (305 mm) or less in length from the top the pipe to the bottom the structural support for the hanger All electrical conduit less than 2 1 /2 inches (64 mm) trade size 3. All rectangular air-handling ducts less than 6 ft 2 (0.56 m 2 ) in cross sectional area or: All round air-handling ducts less than 28 inches (711 mm) in diameter All ducts suspended by hangers 12 inches (305 mm) or less from the top the duct to the bottom the structural support for the hanger; where the hangers are detailed to avoid bending the hangers and their connections. (To eliminate bending moment, flexible connections may be used. See B752 on page 49 or B446 & B446C on page 56) Where lateral restraints are omitted, the piping, ducts, or conduit shall be installed such that lateral motion the piping, duct, or conduit will not cause damaging impact with other systems or structural members, or loss vertical support. NOTE: Reference building code enforced by local authority with jurisdiction for specific requirements, and verify all omissions or exemptions with structural engineer record. 8

12 GENERAL NOTES FOR SEISMIC BRACING GENERAL NOTES FOR SEISMIC BRACING A) The seismic restraint assemblies shown in this pre-approval document are designed to resist vertical loading simultaneously with seismic loading (transverse & longitudinal loading). Design recommendations shown are for single standard weight steel pipes filled with water. Contents other than water shall be evaluated by the user. Pipes other approved materials shall be supported in accordance with their approved installation standards. Details not shown in this pre-approval shall be submitted to OSHPD for approval before installation if necessary. B) This bracing system is limited to the pipe sizes and support details shown. Special consideration must be given for pipe material and connections, insulation, thermal movement, vibration, and building seismic joints. C) Transverse and longitudinal braces shall be no more than 45 above or below the centerline the pipe, duct, or tray. D) All channel and pipe clamp nuts and bolts shall be tightened to the following torques: 1/4"-20 to 6 ft.-lbs. (8 N m) 3/8"-16 to 19 ft.-lbs. (26 N m) 1/2"-13 to 50 ft.-lbs. (68 N m) 5/8"-11 to 65 ft.-lbs. (88 N m) 3/4"-10 to 75 ft.-lbs. (101 N m) E) The transverse and longitudinal bracing spacing listed in Appendix 1 & 2 is based on ductile piping (steel, copper, etc.) with ductile connections (welded, brazed, etc.) and has the following limitations: 1) Transverse bracing shall not exceed 40-0 (12.2 m). Longitudinal bracing shall not exceed 80-0 (24.4 m). 2) Fuel piping shall have transverse bracing 20'-0" (6.1 m) o.c. maximum and longitudinal bracing 40'-0" (12.2 m) o.c. maximum. 3) Non-ductile piping, and piping with non-ductile connections shall have transverse bracing 20'-0" (6.1 m) o.c. maximum and longitudinal bracing 40'-0" (12.2 m) o.c. maximum or 1 /2 the calculated brace spacing indicated in Appendix 1 or 2, whichever is more restrictive. F) Transverse bracing for one pipe section may also act as longitudinal bracing for the pipe section connected to it, if the bracing is installed within 24 inches (609 mm) the elbow or tee similar size. Figures 2 and 4 do not serve as adequate longitudinal braces. 9

13 GENERAL NOTES FOR SEISMIC BRACING G) Branch lines a smaller diameter shall not be used to brace main lines. H) Where rod stiffeners are required a minimum two hanger rod stiffener assemblies shall be installed. (Part number SC-228 or SC-UB) I) It is important to check anchorage details against the applicable building code requirements. Seismic design forces may increase substantially when anchors are considered shallow (embedded less than 8 times the anchor diameter). J) When bracing trapeze type hangers, the bracing shall be attached directly to the trapeze hanger assembly and piping secured to the trapeze assembly with pipe straps. K) A rigid piping system shall not be braced to diff e rent parts a building that may re s p o n d differently during an earthquake. Example: Solid concrete wall and a ro (metal deck filled with lightweight concrete). Special care should be taken to avoid bracing rigid pipe on both sides a building seismic joint without allowing for pipe and building movement. L) The pre-approval document is based on British Units (Inches & Pounds) and values noted in parenthesis (Metric or S.I. Units) are equivalent values. In case conflicts, British Units will be the standards for evaluating the proper application pre-approvals. M) The designer the structure shall determine the adequacy the support structure to carry the load the piping and equipment. Engineer record for a site specific project shall verify that the structure can support the connection loads the hanger rod and the bracing attachments in addition to all other loads. This pre-approval document is not intended for the seismic design the piping itself. The dynamic properties the building structure and piping should be considered when selecting the type piping to be installed. N) Seismic bracing shall not limit the expansion and contraction the piping system. Always consider thermal movements when selecting brace locations and materials. The design for thermal movements is beyond the scope OSHPD pre-approval. P) No portion this pre-approval shall be taken out context and used in other systems, design or purpose. Q) On transverse bracing, the pipe insulation material may be part the brace assembly (i.e) in the load path. In this case the insulating material shall be capable withstanding the lateral forces without damage and shall include a pipe shield for hangers or a pipe saddle for rollers. For longitudinal bracing, clamping must be applied directly to the pipe with any insulation being installed directly over the hanger and brace assembly. In these applications the mechanical engineer record shall be contacted for insulating recommendations. 10

20 TRAPEZE BRACING Trapeze Assembly Bracing 1). Layout piping and/or conduit runs and determine number, size and location items to be supported by the trapeze 2). Determine trapeze support spacing (L T ). This is usually determined by the maximum support spacing the smallest pipe or conduit on the trapeze. 3). Select trapeze supports. a). Determine the total vertical load (T L ) for each trapeze. T L = L T x W T T L = Total vertical load for each trapeze support (lbs.) L T = Trapeze support spacing (ft.) W T = Weight all piping, cable tray, ductwork, conduit, etc. in lbs./ft. supported by the trapeze b). Determine length trapeze, making sure sufficient length is added to attach the all threaded rod and bracing attachments. All channel nuts shall be fully engaged within strut. ( 13 /16 (20mm) minimum distance from edge strut to center line bolt.) c). Select type trapeze member (B22, B22AMIG, etc.) by selecting a member with loading greater than the total load (T L ). See Table 4 on page 22 for strut loading data, noting that the trapeze beam span is the distance between the hanger rods. Also determine whether the applied load is uniform or concentrated, and follow notes on page 22 accordingly. Variations in pipe sizes (simular to concentrated load assembly on page 22) shall be treated as a concentrated load, where as same sized pipes evenly distributed across the span (similar to uniform load assembly on page 22) may be treated as a uniform load. Uniform loads on page 22 are converted to a concentrated load by a 50% reduction. Do not exceed the beam span length given by Table 4A on page 22, which limits overloading due to longitudinal seismic force. d). Determine hanger rod size from Appendix 2 based on total weight (W T ) and trapeze support spacing (L T ). Rod sizes are given for trapeze supports with braces attached and unbraced trapezes. e). Select a hanger rod connection to structure (pages 39 thru 56) that is greater than the hanger rod loads listed in Appendix 2. 4). Select transverse and longitudinal bracing. a). Select bracing detail from Figures b). Determine spacing transverse / longitudinal bracing from Appendix 2 based on total weight (Wt) and the trapeze support span (Lt). Note the corresponding structure attachment type (Roman numeral I - V) for each possible brace interval. When supporting multiple pipe sizes, do not exceed the maximum spacing for the smallest pipe as given in Appendix 1. Verify that the specific forces do not exceed the capacity the pipe clamps on pages 70 & 71. Take care not to exceed maximum allowable brace beam spans as noted on page 11. Consult Table 4 and Table 4A, page 22, for trapeze design considerations. c). Determine if rod stiffener is required (pages 57 & 58). d). Engineer record for a site specific project shall verify that the structure can support the connection loads in addition to all other loads. 5). Review the design and revise layout where loads exceed the limitations the hanger rods, strut trapeze supports, or connection details. 17

26 STRUCTURAL ATTACHMENTS Brace Structural Attachment Selection Procedure 1) Determine structure to be attached to from the following: A) Concrete B) Wood Beam C) Structural Steel 2) Reference structure connection type from Appendix 1 & 2. 3) Choose appropriate structural detail that meets structure connection type. (I, II, III, IV or V) pages 24 thru 38. 4) Determine anchor size. On concrete structure attachments, calculate minimum embedment and minimum distance between anchors. General Notes For Concrete Attachments 1) The minimum embedment values given on pages provide the anchor capacity to reach the design loads shown, but may be considered by the 1997 UBC to be shallow anchors (embedment less that 8 times the anchor diameter). Using shallow anchors may increase the design seismic forc e, depending on the building code used. As an alternative, consider using the following values to avoid shallow anchor issues: Anchor Bolt Dia. 8x Embedment 3/8 3 (76mm) 1/2 4 (101mm) 5/8 5 (127mm) 3/4 6 (152mm) 2) Size and number expansion anchors is based on "without special inspection" values given in ICBO (International Conference Building Officials) Report No dated September 1, 2004, Hilti Kwik Bolt 3 Carbon Steel Allowable Tension and Shear Values. 3) Other anchors may be used providing they are listed in an ICBO ES Evaluation Report, which was tested in accordance with AC01, including the seismic qualification tests AC01 Section 5.6. These values must meet or exceed the values provided in ICBO Report No. 1385, and must be approved by the structural engineer record. OSHPD change order is required for California hospitals. 4) For California Essential Facilities, 50% the expansion type anchor (alternate anchors in a group) shall be pro tested per Appendix 3. Other projects may have similar requirements, check local codes and ordinances. 5) Cast in place concrete anchors require special inspection as indicated in the building code for the local jurisdiction. 6) When slab thickness is less than the minimum allowable, but in excess the minimum anchor embedment, a thru bolt approach may be used if approved by the site engineer. 7) When installing drill-in anchors in existing non-prestressed reinforced concrete, use care and caution to avoid cutting or damaging the existing re i n f o rcing bars. When installing them into existing pre s t re s s e d concrete (pre-or post-tensioned), locate the prestressed tendons by using a non-destructive method prior to installation. Exercise extreme care and caution to avoid cutting or damaging the tendons during installation. Maintain a minimum clearance 1 inch (25mm) between the reinforcement and the drilled-in anchor. 23

42 HANGER ROD ATTACHMENTS Hanger Rod Structure Attachments Selection Procedure 1) Determine structure type to attach hanger rod A) Concrete B) Wood Beam C) Structural Steel 2) Reference rod size and hanger rod load from Appendix 1 & 2. 3) Select a hanger rod attachment detail with a load capacity that meets the hanger rod load General Notes For Concrete Attachments 1) The minimum embedment values given on pages provide the anchor capacity to reach the design loads shown, but may be considered by the 1997 UBC to be shallow anchors (embedment less that 8 times the anchor diameter). Using shallow anchors may increase the design seismic force, depending on the building code used. As an alternative, consider using the following values to avoid shallow anchor issues: Anchor Bolt Dia. 8x Embedment 3/8 3 (76mm) 1/2 4 (101mm) 5/8 5 (127mm) 3/4 6 (152mm) 2) Size and number expansion anchors is based on "without special inspection" values given in ICBO (International Conference Building Officials) Report No dated September 1, 2004, Hilti Kwik Bolt 3 Carbon Steel Allowable Tension and Shear Values. 3) Other anchors may be used providing they are listed in an ICBO ES Evaluation Report, which was tested in accordance with AC01, including the seismic qualification tests AC01 Section 5.6. These values must meet or exceed the values provided in ICBO Report No. 1385, and are approved by the structural engineer record. OSHPD change order is required for California hospitals. 4) For California hospitals and schools, 50% the expansion type anchor (alternate anchors in a group) shall be pro tested per Appendix 3. Other projects may have similar requirements, check local codes and ordinances. 5) Cast in place concrete anchors require special inspection as indicated in the building code for the local jurisdiction. 6) When slab thickness is less than the minimum allowable, but in excess the minimum anchor embedment, a thru bolt approach may be used if approved by the site engineer. 7) When installing drill-in anchors in existing non-prestressed reinforced concrete, use care and caution to avoid cutting or damaging the existing reinforcing bars. When installing them into existing prestressed concrete (pre-or post-tensioned), locate the prestressed tendons by using a non-destructive method prior to installation. Exercise extreme care and caution to avoid cutting or damaging the tendons during installation. Maintain a minimum clearance 1 inch (25mm) between the reinforcement and the drilled-in anchor. 39

The building code uses strength design. (See Special Note page 2 for further information.) These charts cover the vast majority seismic requirements from coast to coast, from Zone 1 to Zone 4 applications, and take into account the many codes which may be referenced for a specific project. The seismic zone, building type, and other factors determine the level seismic force for a particular project. The project design pressional should determine the correct seismic force value using the appropriate building code and local requirements. Use the correct table is very important to ensure that the c o r rect brace spacing and anchorage is provided. See pages 1-8 for more information. 82

Many codes require pipe hangers to be spaced every 10-0 (3.05m) regardless size. Check your local codes. Spacing and capacities are based on water filled standard weight pipe. Closer hanger spacing may be required when additional valves and fittings increase the load. For electrical conduit support spacing and weight conduit filled with conductors information, see B-Line Strut Systems Catalog. 2). The structure connection type is the brace anchorage requirement. See pages 23 thru 38 for brace attachment details. 3). The hanger and rod loads indicates the maximum tension in the rod (and hanger) due to gravity and the additional seismic forces at the braced location. Select a pipe hanger from pages 63 thru 71 that meets the hanger load requirements. Select a rod attachment detail from pages 39 thru 56 that meets the rod load requirements. Be sure to follow the guidelines on page 57 & 58 to see if a rod stiffener is required, due to the length the rod. Rod stiffeners, if necessary, are only required at braced locations. Unbraced hangers do not require rod stiffeners. 4). Braces must be attached within 4 inches (101mm) hanger, see Figure 5, 6 and 8. 5). Table 1 is for steel pipe. Spacing limitations may exist for other types pipe. See Note E) on page 9. 6). Seismic forces include 1 /3 horizontal seismic force applied in vertical direction. 7). Consult appropriate plumbing code for non-braced hanger rod sizes. 8). Charts on pages are for 0.15g (ASD) applications. 86

Many codes require pipe hangers to be spaced every 10-0 (3.05m) regardless size. Check your local codes. Spacing and capacities are based on water filled standard weight pipe. Closer hanger spacing may be required when additional valves and fittings increase the load. For electrical conduit support spacing and weight conduit filled with conductors information, see B-Line Strut Systems Catalog. 2). The structure connection type is the brace anchorage requirement. See pages 23 thru 38 for brace attachment details. 3). The hanger and rod loads indicates the maximum tension in the rod (and hanger) due to gravity and the additional seismic forces at the braced location. Select a pipe hanger from pages 63 thru 71 that meets the hanger load requirements. Select a rod attachment detail from pages 39 thru 56 that meets the rod load requirements. Be sure to follow the guidelines on page 57 & 58 to see if a rod stiffener is required, due to the length the rod. Rod stiffeners, if necessary, are only required at braced locations. Unbraced hangers do not require rod stiffeners. 4). Braces must be attached within 4 inches (101mm) hanger, see Figure 5, 6 and 8. 5). Table 1 is for steel pipe. Spacing limitations may exist for other types pipe. See Note E) on page 9. 6). Seismic forces include 1 /3 horizontal seismic force applied in vertical direction. 7). Consult appropriate plumbing code for non-braced hanger rod sizes. 8). Charts on pages are for 0.30g (ASD) applications. 90

Many codes require pipe hangers to be spaced every 10-0 (3.05m) regardless size. Check your local codes. Spacing and capacities are based on water filled standard weight pipe. Closer hanger spacing may be required when additional valves and fittings increase the load. For electrical conduit support spacing and weight conduit filled with conductors information, see B-Line Strut Systems Catalog. 2). The structure connection type is the brace anchorage requirement. See pages 23 thru 38 for brace attachment details. 3). The hanger and rod loads indicates the maximum tension in the rod (and hanger) due to gravity and the additional seismic forces at the braced location. Select a pipe hanger from pages 63 thru 71 that meets the hanger load requirements. Select a rod attachment detail from pages 39 thru 56 that meets the rod load requirements. Be sure to follow the guidelines on page 57 & 58 to see if a rod stiffener is required, due to the length the rod. Rod stiffeners, if necessary, are only required at braced locations. Unbraced hangers do not require rod stiffeners. 4). Braces must be attached within 4 inches (101mm) hanger, see Figure 5, 6 and 8. 5). Table 1 is for steel pipe. Spacing limitations may exist for other types pipe. See Note E) on page 9. 6). Seismic forces include 1 /3 horizontal seismic force applied in vertical direction. 7). Consult appropriate plumbing code for non-braced hanger rod sizes. 8). Charts on pages are for 0.45g (ASD) applications. 94

Many codes require pipe hangers to be spaced every 10-0 (3.05m) regardless size. Check your local codes. Spacing and capacities are based on water filled standard weight pipe. Closer hanger spacing may be required when additional valves and fittings increase the load. For electrical conduit support spacing and weight conduit filled with conductors information, see B-Line Strut Systems Catalog. 2). The structure connection type is the brace anchorage requirement. See pages 23 thru 38 for brace attachment details. 3). The hanger and rod loads indicates the maximum tension in the rod (and hanger) due to gravity and the additional seismic forces at the braced location. Select a pipe hanger from pages 63 thru 71 that meets the hanger load requirements. Select a rod attachment detail from pages 39 thru 56 that meets the rod load requirements. Be sure to follow the guidelines on page 57 & 58 to see if a rod stiffener is required, due to the length the rod. Rod stiffeners, if necessary, are only required at braced locations. Unbraced hangers do not require rod stiffeners. 4). Braces must be attached within 4 inches (101mm) hanger, see Figure 5, 6 and 8. 5). Table 1 is for steel pipe. Spacing limitations may exist for other types pipe. See Note E) on page 9. 6). Seismic forces include 1 /3 horizontal seismic force applied in vertical direction. 7). Consult appropriate plumbing code for non-braced hanger rod sizes. 8). Charts on pages are for 0.50g (ASD) applications. 98

Many codes require pipe hangers to be spaced every 10-0 (3.05m) regardless size. Check your local codes. Spacing and capacities are based on water filled standard weight pipe. Closer hanger spacing may be required when additional valves and fittings increase the load. For electrical conduit support spacing and weight conduit filled with conductors information, see B-Line Strut Systems Catalog. 2). The structure connection type is the brace anchorage requirement. See pages 23 thru 38 for brace attachment details. 3). The hanger and rod loads indicates the maximum tension in the rod (and hanger) due to gravity and the additional seismic forces at the braced location. Select a pipe hanger from pages 63 thru 71 that meets the hanger load requirements. Select a rod attachment detail from pages 39 thru 56 that meets the rod load requirements. Be sure to follow the guidelines on page 57 & 58 to see if a rod stiffener is required, due to the length the rod. Rod stiffeners, if necessary, are only required at braced locations. Unbraced hangers do not require rod stiffeners. 4). Braces must be attached within 4 inches (101mm) hanger, see Figure 5, 6 and 8. 5). Table 1 is for steel pipe. Spacing limitations may exist for other types pipe. See Note E) on page 9. 6). Seismic forces include 1 /3 horizontal seismic force applied in vertical direction. 7). Consult appropriate plumbing code for non-braced hanger rod sizes. 8). Charts on pages are for 0.75g (ASD) applications. 102

Many codes require pipe hangers to be spaced every 10-0 (3.05m) regardless size. Check your local codes. Spacing and capacities are based on water filled standard weight pipe. Closer hanger spacing may be required when additional valves and fittings increase the load. For electrical conduit support spacing and weight conduit filled with conductors information, see B-Line Strut Systems Catalog. 2). The structure connection type is the brace anchorage requirement. See pages 23 thru 38 for brace attachment details. 3). The hanger and rod loads indicates the maximum tension in the rod (and hanger) due to gravity and the additional seismic forces at the braced location. Select a pipe hanger from pages 63 thru 71 that meets the hanger load requirements. Select a rod attachment detail from pages 39 thru 56 that meets the rod load requirements. Be sure to follow the guidelines on page 57 & 58 to see if a rod stiffener is required, due to the length the rod. Rod stiffeners, if necessary, are only required at braced locations. Unbraced hangers do not require rod stiffeners. 4). Braces must be attached within 4 inches (101mm) hanger, see Figure 5, 6 and 8. 5). Table 1 is for steel pipe. Spacing limitations may exist for other types pipe. See Note E) on page 9. 6). Seismic forces include 1 /3 horizontal seismic force applied in vertical direction. 7). Consult appropriate plumbing code for non-braced hanger rod sizes. 8). Charts on pages are for 1.00g (ASD) applications. 106

The building code uses strength design. (See Special Note on page 2 for further information.) These charts cover the vast majority seismic requirements from coast to coast, from Zone 1 to Zone 4 applications, and take into account the many codes which may be referenced for a specific project. The seismic zone, building type, and other factors determine the level seismic force for a particular project. The project design pressional should determine the correct seismic force value using the appropriate building code and local requirements. Use the correct table is very important to ensure that the correct brace spacing and anchorage is provided. See pages 1-8 for more information. 108

148 TRAPEZE BRACING Footnotes 1. It is not necessary to install both transverse braces and longitudinal braces on the same trapeze support. For example, it is common to install transverse braces on trapezes every 40 ft., and then install both transverse and longitudinal braces every 80 ft. 2. The structure connection type is the brace anchorage requirement. See pages 23 thru 38 for brace attachment details. 3. Any combination brace interval and structure connection type (anchor size) may be used for a given system weight and support span. For example, it is not necessary to use structure connection type II for both transverse and longitudinal braces. Often longitudinal braces are spaced at a greater distance, and would require a larger anchor when attaching to structure. 4. The bracing intervals listed are maximums. They are rounded down to facilitate construction. For example, it is common to use a longitudinal bracing interval that is twice the transverse spacing. 5. The rod load indicates the maximum tension in the rod due to gravity and 1 /3 the horizontal seismic force applied in the vertical direction for unbraced trapezes. For trapezes with braces attached, the rod load also includes additional seismic loads. Note that the rod loads at braced locations are significantly higher than unbraced trapezes. Select a hanger rod attachment detail from pages 39 thru 56 that meets the load requirements. 6. The minimum rod size is given for both braced and unbraced trapezes. Due to the additional seismic forces at braced trapezes, the rod sizes may be significantly larger. Be sure to follow the guidelines on page 57 to see if a rod stiffener is required, due to the length the rod. Rod stiffeners, if necessary, are only required at braced locations. Unbraced trapezes never require rod stiffeners. 7. Seismic forces for charts in Appendix 2 (pages ) include 1 /3 horizontal seismic force applied in vertical direction. 8. Charts in Appendix 2 (pages ) are for the seismic force levels (%g) listed on those pages. 145

149 Appendix 3 Pro Test Instructions For Concrete Anchors (CAN 1925B.3.5) State California Office Statewide Health Planning and Development TEST VALUES Hardrock or Lightweight Concrete Anchor Wedge Sleeve Shell Dia. Load Torque Load Torque Load Torque (in.) (lbs) (ft-lbs) (lbs) (ft-lbs) (lbs) (ft-lbs) 1 / / / / / / Notes 1. Anchor diameter refers to the thread size for the Wedge & Shell categories and to the anchor outside diameter for the Sleeve category. 2. Apply pro test loads to Wedge & Sleeve anchors without removing the nut if possible. If not, remove nut and install a threaded coupler to the same tightness as the original nut using a torque wrench and apply load. 3. For Sleeve/Shell internally threaded categories, verify that the anchor is not prevented from withdrawing by a baseplate or other fixtures. If restraint is found, loosen and shim or remove fixture(s) prior to testing. 4. Reaction loads from test fixtures may be applied close to the anchor being tested, provided the anchor is not restrained from withdrawing by the fixture(s). 5. Shell type anchors should be tested as follows: a. Visually inspect 25% for full expansion as evidenced by the location the expansion plug in the anchor body. Plug location a fully expanded anchor should be as recommended by the manufacturer, or, in the absence such recommendation, as determined on the job site following the manufacturer s installation instructions. At least 5% the anchors shall be pro loaded as indicated in the table above, but not less than three anchors per day for each different person or crew installing anchors, or; b. Test 50% the installed anchors per Section 1925B Test equipment (including torque wrenches) is to be calibrated by an approved testing laboratory in accordance with standard recognized procedures. 7. Torque test values for Shell type anchors can occur on an case-by-case basis when test procedures are submitted and approved by the enforcement agency. 8. The following criteria apply for the acceptance installed anchors; Hydraulic Ram Method: The anchor should have no observable movement at the applicable test load. For wedge and sleeve type anchors, a practical way to determine observable movement is that the washer under the nut becomes loose. Torque Wrench Method: The applicable test torque must be reached within the following limits; Wedge or Sleeve type: One-half ( 1 /2) turn the nut. One-quarter ( 1 /4) turn the nut for 3 /8 inch sleeve anchor only. 9. Testing should occur a minimum 24 hours after installation the subject anchors. 10. If the manufacturer s recommended installation torque is less than the test torque noted in the table, the manufacturer s recommended installation torque should be used in lieu the tabulated values. 11. All tests shall be performed in the presence the Inspector Record. 146

150 Appendix International Building Code As defined in the 2003 International Building Code, Chapter 16, Section 1621, the seismic horizontal force, F p, shall be calculated per Section 9.6 ASCE 7: F p = 0.4a ps DS I p (1 + 2 z )W p R p h Except that: F p shall not be less than 0.3 S DS I p W p and need not be more than 1.6 S DS I p W p. Where: F p = Seismic Force Level a p = Amplification Factor (Table ASCE 7) R p = Component Response Modification Factor, (Table ASCE 7) which varies from 1.0 to 5.0 = 1.0 for shallow embedded anchors where the embedment length-to-diameter ratio is less than 8. (Section ASCE 7) i.e. a 1 /2" diameter anchor embedded less than 4" in concrete. I p = Importance Factor (Section ASCE 7) = 1.5 for Life-safety components required to function after an earthquake, buildings containing hazardous or flammable material, and for storage racks open to the general public. = 1.0 for all other occupancies S DS = Design spectral response acceleration at short period several factors: Seismic zone, Soil Property Type, and Distance from known fault.

Note: (z) shall not be taken less than 0.0 = Average structure ro elevation with respect to grade. 147

151 Example: Deeply Embedded Anchors In this example a cable tray system is suspended on the 1st floor a 40-foot tall, 2-story surgical center. The cable tray is actually suspended from the 2nd floor, which has an elevation 20 feet above grade. The location the surgical center is in Memphis, TN with a rock soil prile. F p = 0.4a ps DS I p (1 + 2 z )W p R p h a p = (2.5) for a cable tray (Table ASCE 7) R p = (5.0) for a cable tray system anchored with deep embedded anchors (Table ASCE 7) I p = (1.5) for an essential facility in Seismic Use Group III which will require continued use following an earthquake (Section ASCE 7) S DS = (0.4) extended calculations shown below (Section ASCE 7) Where, S DS = (2/3) S MS = (0.4) (Section ASCE 7) S MS = F a S S = (0.6) (Section ASCE 7) F a = (1.0) using straight line interpolation the Mapped spectral Acceleration (S S ) and Site Class (Table a ASCE 7) S S = (0.6) Mapped Spectral Acceleration for short periods (Section ASCE 7) Site Class = B for Rock (Table ASCE 7) z h = 20 feet, for the elevation the floor used to support the cable tray = 40 feet, for the average elevation the structure ro F p = 0.4(2.5)(0.40)(1.5) ( )W p = 0.24W p = 0.24g Check if value falls within the allowed limits: F p shall not be taken less than, 0.3S DS I p W p = 0.3(.40)(1.5)W p =.18g F p shall not be greater than, 1.6S DS I p W p = 1.6(.40)(1.5)W p = 0.96g 0.24g > 0.18g, thus allowing the use 0.24g 148

152 To convert this F p from a strength design, as just determined from the building code, to an Allowable Stress Design (ASD) used in the Cooper B-Line Seismic Restraints Manual divide by 1.4. F p = 0.24g = 0.17g (ASD) g is the Allowable Stress Design Seismic Load Factor determined from 2003 International Building Code. Special Note: Installations using concrete anchors installed with an embedment length-to-diameter ratio less than 8, also referred to as shallow embedment anchors, have an adjusted Component Response Factor. The adjusted factor being R p = 1.5. Example Two: Shallow Embedded Anchors In this example a cable tray system is suspended on the 1st floor a 40-foot tall, 2-story surgical center in California. The cable tray is actually suspended from the 2nd floor, which has an elevation 20 feet above grade. The location the surgical center is in seismic zone 4 with a rock soil prile, however shallow embedded anchors (length-to-diameter ratio less than 8) are used at brace locations. F p = 0.4a ps DS I p (1 + 2 z )W p R p h a p = (2.5) for a cable tray (Table ASCE 7) R p = (1.5) for a cable tray system anchored with shallow embedded anchors (Section ASCE 7) I p = (1.5) for an essential facility in Seismic Use Group III which will require continued use following an earthquake (Section ASCE 7) S DS = (0.4) extended calculations shown below (Section ASCE 7) Where, S DS = (2/3) S MS = (0.4) (Section ASCE 7) S MS = F a S S = (0.6) (Section ASCE 7) F a = (1.0) using straight line interpolation the Mapped spectral Acceleration (S S ) and Site Class (Table a ASCE 7) S S = (0.6) Mapped Spectral Acceleration for short periods (Section ASCE 7) Site Class = B for Rock (Table ASCE 7) z h = 20 feet, for the elevation the floor used to support the cable tray = 40 feet, for the average elevation the structure ro F p = 0.4(2.5)(0.40)(1.5) ( )W p = 0.80W p = 0.80g

F p = 0.80g = 0.57g (ASD) g is the Allowable Stress Design Seismic Load Factor determined from 2003 International Building Code. 150

154 1999 Standard Building Code As defined in the 1999 Standard Building Code, Chapter 16, Section , the seismic horizontal force, F p, may be calculated using the following formula: Where, F p = Seismic Force Level F p = A v C c Pa c W c A v = Peak velocity-related acceleration (Section ) C c = Seismic coefficient for mechanical, electrical components and systems (Table A) P = Performance criteria factor (Table A) a c = Attachment amplification factor (Table B) W c = Operating weight the mechanical, electrical component system Example This example is for a primary cable tray system suspended in a surgical center in Memphis, TN. F p = A v C c Pa c W c A v = (0.20) for the Memphis, TN area (Table A) C c = (2.0) for a primary cable tray system (Table A) P = (1.5) for a primary cable tray system (Table A) - Group III for an essential Surgery or Emergency Treatment Facility (Table ) a c = Always (1.0) when using a fixed connection type (Table B) F p = 0.2(2.0)(1.5)(1.0)W c =.6W c =.6g To convert F p from a strength design, as just determined from the building code, to an Allowable Stress Design (ASD) as used in the Cooper B-Line Seismic Restraints Manual divide by 1.4. F p = 0.60g = 0.43g (ASD) g is the Allowable Stress Design Seismic Load Factor determined from 1999 Standard Building Code. 151

155 1997 Uniform Building Code As defined in the 1997 Uniform Building Code, Chapter 16, Section 1632, the seismic horizontal force, F p, may be calculated using the following formula: F p = a pc a I p (1 + 3 hx )W p R p h r Except that: F p shall not be less than 0.7 C a I p W p and need not be more than 4 C a I p W p. Where: F p = Seismic Force Level a p = Amplification Factor (Table 16-O) R p = Component Response Modification Factor (Table 16-O) = 3.0 for electrical, mechanical and plumbing equipment and associated conduit, ductwork and piping. = 1.5 for installations using concrete anchors with an embedment-to-diameter ratio less than 8. i.e. a 1 /2" diameter concrete anchor with an embedment less than 4" inches.

This is an accumulation several factors: (Table 16-Q) Seismic Zone (Table 16-I), Soil Property Type (Table 16-J), and Distance from known faults. (Table 16-S, and Table 16-U) h x = Element or component attachment elevation with respect to grade. Note: h x shall not be taken less than 0.0 h r = Structure Ro Elevation with respect to grade. 152

156 Example One, Deeply Embedded Anchors: Cable tray system is suspended on the 1st floor a 40-foot tall, 2-story surgical center in California. The cable tray is actually suspended from the bottom the 2nd floor, which has an elevation 20 feet above grade. Location the surgical center is in seismic zone 4 with a rock soil prile. F p = a pc a I p (1 + 3 hx )W p R p h r a p = 1.0 from Table 16-O C a =.40Na from Table 16A-Q, which is combination Seismic Zone factor and Soil prile type Where, Z =.40 for seismic zone 4 applications (Table 16-I) Soil Prile Type = S B for rock sediment (Table 16-J) Seismic Source Type = B for faults other than Type A & C (Table 16-U) Na = 1.0, for 5 km from known seismic source (Table 16-S) I p = (1.5) for an essential surgery and emergency treatment area (Table 16-K) R p = (3.0) for cable trays supported with deep embedded anchors (Table 16-O) h x = 20 feet, for the elevation the floor used to support the cable tray h r = 40 feet, for the elevation the structure ro Check if value falls within limits: F p = (1.0)((0.40(1.0))(1.5) ( )W p = 0.50W p = 0.50g F p shall not be taken less than, 0.7C a I p W p = 0.7(.40)(1.5)W p =.42g F p shall not be greater than, 4.0C a I p W p = 4.0(.40)(1.5)W p = 2.4g 2.4g >.5 > 0.42g Therefore allowing the use 0.50g To convert this F p from a strength design, as just determined from the building code, to an Allowable Stress Design (ASD) used in the Cooper B-Line Seismic Restraints Manual divide by 1.4. F p = 0.50g = 0.36g (ASD) g is the Allowable Stress Design Seismic Load Factor determined from 1997 Uniform Building Code. Special Note: Installations using concrete anchors installed with an embedment length-to-diameter ratio less than 8, also referred as shallow embedment anchors, have an adjusted Component Response Factor being R p =

157 Example Two, Shallow Embedded Anchors: In this example a cable tray system is suspended on the 1st floor a 40-foot tall, 2-story surgical center in California. The cable tray is actually suspended from the 2nd floor, which has an elevation 20 feet above grade. Location the surgical center is in seismic zone 4 with a rock soil prile, however shallow embedment anchors (length-to-diameter ratio less than 8) are used at brace locations. F p = a pc a I p (1 + 3 hx )W p R p h r a p = 1.0 from Table 16-O C a = (.40Na) which is combination seismic zone factor and soil prile type from (Table 16-Q) Where, Z =.40 for seismic zone 4 applications (Table 16-I) Soil Prile type = S B for rock sediment (Table 16-J) Seismic Source Type = B for faults other than Type A & C (Table 16-U) Near Source Factor = 1.0 for 5 km from known seismic source (Table 16-S) I p = (1.5) for an essential surgery and emergency treatment areas (Table 16-K) R p = (1.5) for cable trays supported with shallow embedded anchors (Table 16-O) h x h r = 20 feet, for the elevation the floor used to support the cable tray = 40 feet. for the elevation the structure ro F p = (1.0)((0.40(1.0))(1.5) ( )W p = 1.0W p = 1.0g Check if value falls within limits: F p shall not be taken less than, 0.7C a I p W p = 0.7(.40)(1.5)W p =.42g F p shall not be greater than, 4.0C a I p W p = 4.0(.40)(1.5)W p = 2.4g 2.4g > 1.0g > 0.42g Therefore allowing the use 1.0g To convert this F p from a strength design, as just determined from the building code, to an Allowable Stress Design (ASD) used in the Cooper B-Line Seismic Restraints Manual divide by 1.4. F p = 1.0g = 0.71g (ASD) g is the Allowable Stress Design Seismic Load Factor determined from 1997 Uniform Building Code for shallow embedment anchors. 154

158 1999 BOCA (Building Officials and Code Administrators) As defined in the 1999 BOCA, Chapter 16, Section , the seismic horizontal force, F p, may be calculated using the following formula: Where, F p = Seismic Force Level F p = A v C c Pa c W c A v = Peak velocity-related acceleration (Section ) C c = Seismic coefficient for mechanical, electrical components and systems (Table (1)) P = Performance criteria factor (Table (1)) a c = Attachment amplification factor (Table (2)) W c = Operating weight the mechanical, electrical component system Example This example is for a primary cable tray system suspended in a surgical center in St. Louis, MO. F p = A v C c Pa c W c A v = (0.15) for the St. Louis, MO area (Figure (1)) C c = (2.0) for a primary cable tray system (Table (1)) P = (1.5) for a primary cable tray system (Table (1)) - Group III for an essential Surgery or Emergency Treatment Facility (Table ) a c = Always (1.0) when using a fixed connection type (Table (2)) F p = 0.15(2.0)(1.5)(1.0)W c =.45W c =.45g To convert F p from a strength design, as just determined from the building code, to an Allowable Stress Design (ASD) as used in the Cooper B-Line Seismic Restraints Manual divide by 1.4. F p = 0.45g = 0.32g (ASD) g is the Allowable Stress Design Seismic Load Factor determined from the 1999 BOCA. 155
