3 STANDARD JOIST PROFILES Standard and Special Profiles All standard joist profiles, K-Series, LH-Series and DLH-Series, are available with either under-slung or square ends, with parallel chords or with single or double pitched top chords with pitches up to 1/2 inch per foot. KCS-Series joists are available with parallel chords only with either under-slung or square ends. The depth indicated in joist designation is determined by the depth of single-pitched joists at the center of span and at ridge line of double-pitched joists. All standard joist profiles will be provided with standard SJI camber unless otherwise specified on structural drawings. PARALLEL CHORD SINGLE PITCHED TOP CHORD DOUBLE PITCHED TOP CHORD SPECIAL JOIST PROFILES Special joist profiles, SP-Series, shown are also available. SP-Series joists are available with either under-slung or square ends. Structural drawings must include all dimensions as indicated along with all loading requirements. All SP-Series joists will be furnished with no camber unless specified otherwise on structural drawings. Scissor and Arch joists may induce horizontal forces to the supporting structure. Anchorage conditions and drift limitations should be considered by the specifying professional.

Although standard joists, including KCS s, K-Series are designed specifically to support uniformly distributed loads applied to the top chord, research conducted by the Steel Institute, using second-order inelastic analysis, has demonstrated that the localized accumulation of uniform design loads of up to 100 pounds within any top or bottom chord panel has a negligible effect on the overall performance of the joist, provided that the load is applied to both chord angles in a manner which does not induce torsion on the chords. Concentrated loads in excess of 100 pounds, or which do not meet the criteria outlined above, must be applied at joist panel points or field installed web members must be utilized as shown in the detail above. New Millennium can provide a specially designed joist with the capability to withstand point loads without the added members if this requirement and the exact location and magnitude of the loads are shown on the structural drawings. Also, New Millennium can consider the worst case for both the shear and bending moment for a traveling load with no specific location. When a traveling load is specified, the structural drawings should indicate whether the load is to be applied at the top or bottom chord, and at any panel point, or at any point with the local bending effects considered.

For lengths exceeding 100, a camber equal to Span/300 shall be used. The specifying professional shall give consideration to coordinating camber with adjacent framing. Special camber can be provided where required, at an additional cost. Nonstandard cambers must be indicated on structural drawings. Discover the easiest way to specify Steel s and Girders: 4

5 EFFICIENT ALTERNATIVE TO KCS JOIST Load Zone s When the approximate locations of concentrated loads are known, the designer has the opportunity to design a more efficient joist. These joists can be designed to support concentrated loads residing in specific areas defined as load zones. With boundaries of zones defined and the corresponding concentrated load specified, New Millennium can design a more efficient joist. 1. Load zone joists can be designated as either KZ (K-Series) or LHZ (LH-Series) joists. The following design example shows KZ joists in place of standard KCS joists. The same design approach can be used for LHZ joists in place of standard LH-Series joists. 2. Shear and moment envelopes are developed for all load cases within the zones and the joists are designed accordingly, including any stress reversal which may occur. 3. The designer may specify as many loads and corresponding load zones as needed. The fewer zones specified, the more efficient the joist will be. 4. chords and web members will be designed to adequately support all specified load combinations. If a concentrated load does not occur at a panel point, then a field installed web member must be placed from a panel point to the point of concentrated load. Alternatively, some portion of the load may be specified as a bending load that may be located between panel points. This option eliminates the requirement for a field installed web member, at the expense of a larger chord size. 5. chords will be checked so that bridging utilized for adjacent joists will be adequate for the load zone joists. 6. How to specify load zone joists: The figure shown below is a typical framing plan. There are two load zones indicated with hatched lines. The Zone A boundary covers an area 2 feet from the left side to 12 feet from the left side over three joists. The Zone B boundary covers an area beginning 10 feet from the left side to 17 feet from the left side over 6 joists. Zone A will have a 1000 pound concentrated load which may occur anywhere within the zone. Zone B will have a 2000 pound concentrated load occurring anywhere within the zone. The joists not affected by the concentrated loads are designated as 26K200/100. The first three joists from the top of the plan are affected by Zones A and B and will be labeled as: 26KZ200/100 (A,B). The next three joists are affected by only Zone B. They will be labeled as: 26KZ200/100 (B). In near proximity with the corresponding framing plan the load zone information should be listed as follows: Zone A 1000 lb. 2 to 12 Zone B 2000 lb. 10 to 17 Note that the dimensions are from one end of the framing plan. Actual dimensions may be placed on the framing plan as shown below. 7. Compare the weight of the 26KZ200/100 (A,B) joist to a KCS joist selected to carry the same loads: Determining the shear and moment envelopes we find that (Mmax = 1077 in. kips and the Max. Shear = 7324 lbs.) the KCS selection would be a 26KCS4 per KCS load table). The KCS joist weighs 16.5 lbs. per foot. The load zone joist design shows that the 26KZ200/100 (A,B) weighs 12.4 lbs. per foot. Multiplying the weight per foot difference (16.5 minus 12.4 equals 4.1) times the length of the joist (50 feet) reveals that the load zone joist would weigh 204 lbs. less than the KCS joist. Note: If using LRFD, be sure specify it as such and state whether the specified loads are factored or unfactored. 50'-0 2'-0 10'-0 10'-0 7'-0 26 KZ 200/100 (A,B) do do 26 KZ 200/100 (B) do do 26 K 200/100 do do do do Discover the easiest way to specify Steel s and Girders: 5

6 OSHA Highlights New Millennium joist products are fabricated to meet the erection requirements of the Occupational Safety and Health Administration (OSHA). Field compliance with OSHA is necessary. This section summarizes the OSHA Safety Standards for Steel Erection, 29 CFR, Open Web Steel s requirements governing joist fabrication. FIELD-BOLTED JOISTS Field-bolted bearing connections to steel framing are required where constructability allows, for joists in bays of 40-0 or more, except where joists are preassembled in panels. Bay is defined as the length from center of steel or from face of wall. Slotted holes are provided in joist seats for this initial connection typically made with ASTM-A307 bolts. The final connection should be welded or as designated by the specifying professional. COLUMN JOISTS s at columns that are not framed in at least two directions with structural steel, are required to be bolted at the column to provide lateral stability to the column during erection. bottom chords are to be extended at columns onto vertical stabilizer plates to prevent overturning during erection. Hoisting cables are to remain until both ends of joists are field-bolted and bottom chords are restrained by column stabilizer plates. Where joists do not occur at columns and columns are not framed in at least two directions by structural steel, the joists on both sides of column, are to be field-bolted at both ends where constructability allows. Hoisting cables are to remain until joists are field-bolted and an alternate means of stabilizing joists is installed. OSHA has adopted an enforcement policy effective indefinitely, for column joists or near column joists spanning 60-0 or less, as referenced in (a) (3). The policy is as follows: for all joists at or near columns that span 60 feet or less, employers will be considered to be in compliance with (a) (3) if they erect these joists either by: (1) installing bridging or otherwise stabilizing the joist prior to releasing the hoisting cable, or (2) releasing the hoisting cable without having a worker on the joists. Column joists and near column joists spanning more than 60-0 shall be set in tandem with all bridging installed and field-bolted at both ends where constructability allows, prior to releasing hoisting cables. New Millennium will place a DANGER tag as shown, on these column joists and near column joists to inform erectors of the OSHA requirements. Discover the easiest way to specify Steel s and Girders: 6

7 ERECTION STABILITY BRIDGING OSHA Highlights Where the span of the joist is equal to or greater than the span shown in Tables A and B below, the following shall apply: a row of bolted diagonal Erection Stability Bridging shall be installed near the mid-span of the joist and anchored prior to releasing hoisting cables. s not listed in Tables A and B, do not require Erection Stability Bridging through spans per SJI Specification 5.2 or The spans indicated in Tables A and B, are defined as follows: from center of steel support or from 4 onto supporting wall for K-Series joists and 6 onto supporting wall for LH and DLH-Series joists. Where the span of the joist is over 60-0 through the following shall apply: all rows of bridging shall be bolted diagonal bridging, two rows of bolted diagonal Erection Stability Bridging shall be installed near the third points of the joist and anchored prior to releasing hoisting cables. Where the span of the joist is over the following shall apply: all rows of bridging shall be bolted diagonal Erection Stability Bridging installed and anchored prior to releasing hoisting cables.

Under certain conditions changes are necessary and will be noted on the joist placement drawings. The New Millennium standard connection for Girders to columns is 13/16 x 1 1/2 slots utilizing a 5 gage with ASTM A325 3/4 diameter bolts (bolts are by others). In addition to the bolted connection, welds can also be specified if required to transmit horizontal forces. The final connection shall be made by welding or as designated by the specifying professional. Stabilizer plates (not sized nor provided by New Millennium) are required on the columns located at the bottom chord of the Girder to brace the Girder from overturning during the erection process. Welding the bottom chord to the stabilizer plate should not be done unless required to resist horizontal forces. This should only be done after the dead loads have been applied. s are connected to the Girders by welding except that joists 40 and longer shall be bolted to Girders. The Girder bottom chord must be braced so that its slenderness ratio about the Y axis does not exceed 240. New Millennium will supply bottom chord braces as required by the design.

15 Standard Girder Details and Notes JOISTS GIRDERS USED AS PART OF A RIGID MOMENT FRAME The design of rigid moment frames using Girders is very similar to that of wide-flange beams. End fixity is achieved by restraining the rotation at the ends of the Girders. As with wide-flange beams, there are several methods of achieving this fixity, and for each approach specific design, fabrication, and erection concerns must be considered. With close coordination between the specifying professional and New Millennium Building Systems, material savings may be achieved without increasing fabrication or erection cost. In some cases, it is possible to attain savings in several phases of the project. Advantages of using Girders as part of a lateral load resistant frame include material efficiencies and a more evenly distributed diaphragm load path, as well as decreased erection cost. Material efficiencies may be achieved utilizing Girder chords in continuity moments as well as lateral frame moments. By collecting the diaphragm loads at each frame line, the diaphragm shear requirements and attachment may be reduced, as compared to using braced frames or shear walls at only a few locations. TECHNICAL ISSUES At the top chord, the connection can be problematic since a standard anchorage condition, in which the seat is welded to the column cap plate, develops an eccentric moment in the top-chord of the Girders. When this eccentric moment becomes large, it may govern the size of the Girder top chord, or result in expensive chord reinforcement. The best way to minimize the effects of this moment is to either design the seat and weldment of the joist and Girder seat angles to the cap plate as an extension of the column; with sufficient strength and stiffness to absorb eccentric moment from the anchorage point to the top-chord, or to install a mechanism to tie the Girder top chords together, thereby eliminating the eccentricity all-together. The following details illustrate this load path eccentricity issue, as well as some common methods used to achieve a more direct load path.

TOP CHORD WIDTH AND BOTTOM CHORD BRACES The tables below may be used to solve for the approximate top chord width and the required number of bottom chord braces for Girders. Use the formulas below to solve for half of total top chord area (TCA) and for half of total bottom chord area (BCA). After calculating the TCA and BCA, determine the approximate top chord width and the number of bottom chord braces by checking across the same table row under the appropriate column heading. For even joist spaces on the Girder: TCA =.03xPxSxN 2 /D BCA =.026xPxSxN 2 /D For odd joist spaces on the Girder: TCA =.03xPxSx(N 2-1)/D BCA =.026xPxSx(N 2-1)/D Where: P = panel point load (kips) S = joist spacing (ft.) N = number of joist spaces D = Girder depth (in.) Example: Assume that the Girder size is 48G8N9.5K x 40 (8 joist 5 ) in length. TCA = 0.03x 9.5x5x8 2 /48 = falls in the 4th row and the approximate TC width = 8 1/8. BCA = 0.026x9.5x5x8 2 /48 = falls in the 3rd row and since the length is 40, the number of bottom chord braces required = one at mid-span. Note: Additional bottom chord braces may be required by design. For critical dimensions, the top chord width needs to be verified by New Millennium.

17 Bill of Materials Instructions CALCULATING JOIST GIRDER NET UPLIFT Girder net uplift is calculated by determining the amount of roof area (tributary area) supported by each girder panel point. It is applied in the form of a Kip load at each joist bearing location. To calculate Girder net uplift, use the formula and example supplied below. The example shown is based on a net uplift of 10 psf and framing as indicated in figure below. (1/2 Near Bay + 1/2 Far Bay ) x Net Uplift (psf) x Largest Space / 1000 Example: ( ) x 10 x 4 / 1000 = 1.4 Kips Girder net uplift should be included at the end of the designation as shown 24G7N10.0K1.4 Tributary area 20'-0" 15'-0" 2'-0" 7 4'-0" = 28'-0" Beam 24G7N10.0K1.4 2'-0" Beam 40'-0" Far bay 30'-0" Near bay GIRDER SEAT TYPE Standard bearing seat is R type extended end (Reinforced) for Girders unless specified otherwise on structural drawings. OSHA HOLES When OSHA holes are required for joists bearing on a Girder, specify which side requires holes. In the example shown below, a pair of holes will be provided at /4 (A) from the left (tagged) end, and then at every 4-0 (N) intermediate panel location on far side as denoted by placing an F in the O/H column. Unless noted otherwise, top chord holes are provided in the standard configuration listed next to the diagram on the Girder BOM. MAX. MINIMUM BEARING Achieving minimum bearing as specified by SJI, on lists provided by the Customer is the responsibility of the Customer. The maximum portion of the seat that may hang off of the inside edge of the support (see figure above), and still allow the member to achieve minimum bearing is as follows: 1 1/2 for K-Series joists, 2 for LH, DLH-Series joists, and 2 for Girders. These are maximum values allowed by SJI and require special design consideration for masonry/concrete bearing conditions. Discover the easiest way to specify Steel s and Girders: 17

22 Economical Design Guide ECONOMICAL LOAD TABLES The following Economical Design Guide Load Tables are provided to aid designers in selecting the most economical joist for a given span and loading condition. The joist selections shown are listed based on production costs starting with the lowest cost joist for each span from 10 feet through 240 feet. Refer to following page for definition of Span. Bridging and erection costs have not been considered in the joist selections. The tables include K, LH and DLH-Series joists. Total load capacities are listed for both LRFD and ASD load conditions. Live loads which will produce an approximate deflection of 1/240 or 1/360 of the span are also listed. The tables also include an approximate weight per foot of each joist selection. The tables have been shaded to indicate the joist selections requiring the installation of bolted diagonal bridging. Designers should consider erection costs associated with the bridging requirements when making joist selections. Where the joist designation is shaded RED, SJI requires the row of bridging nearest to mid-span to be bolted diagonal and shall be completely installed prior to releasing the hoisting cables. Where the joist designation is shaded BLUE, SJI requires all rows of bridging to be bolted diagonal with the two rows nearest to the third points completely installed prior to releasing the hoisting cables. Where the joist designation is shaded GRAY, SJI requires all rows of bridging to be bolted diagonal completely installed prior to releasing the hoisting cables. LRFD vs. ASD DESIGN EXAMPLE For most joist applications, the designer can potentially select a more economical joist by specifying LRFD load combinations. For example: Given joist with a 50-0 span where Dead Load = 20 psf, and Live Load = 30 psf. Spacing between s is 6-0 (roof application). The required Dead Load = 20 psf x 6 ft. = 120 plf, and the required Live Load = 30 psf x 6 ft. = 180 plf. LRFD Load Case: Using LRFD load case, the required factored load capacity for the joist is (1.2 x DL x LL) = (1.2 x 120 plf x 180 plf) = 432 plf. The Economical Load Tables shows that for 50 ft. joist span the designer should choose a joist with LRFD load capacity of 436 plf. The table also shows that the service Live Load capacity for deflection of 1/240 of span (typical for roof application) is 249 plf >180 plf (required service LL). The most economical joist under LRFD load case is a 30K10 (joist weight = 11.5 plf). ASD Load Case: Using ASD load case, the required service load capacity for the joist is (DL + LL) = (120 plf plf) = 300 plf. The Economical Load Tables shows that for 50 ft. joist span the designer should choose a joist with ASD load capacity of 333 plf. The most economical joist under ASD load case is a 30K11 (joist weight = 13.1 plf). The designer should note that a more economical joist design can be selected using LRFD load case. This condition is also true when using the published SJI Load Tables. Consider the previous example, where the maximum joist depth is 30 inches. Based on the LRFD SJI Load Table the 30K10 with a factored-load capacity of 436 plf > 432 plf (required factored TL) is selected. Based on the ASD SJI Load Table the 30K10 only has a service-load capacity of 291 plf < 300 plf (required TL) therefore the heavier 30K11 with a service-load capacity of 333 plf > 300 plf (required TL) is selected. Again, it is shown that the LRFD load case can potentially allow the designer to select a more economical joist design. The LRFD design methodology is particularly economically advantageous for conditions with a Design Live Load of less than three times the Design Dead Load.

65 Top Chord Extensions K-Series The following LRFD and ASD Load Tables for K-Series TOP CHORD EXTENSIONS and EXTENDED ENDS are based on the Steel Institute 44th Edition Standard Specifications SJI extensions are commonly furnished to support a variety of overhang conditions. The two TYPES of extensions are pictured below. The first is the TOP CHORD EXTENSION or S TYPE, which has only the top chord angles extended. The second is the EXTENDED END or R TYPE in which the end bearing depth (2 1/2 inches standard) is maintained over the entire length of the extension. The S TYPE extension is so designated because of its Simple nature whereas the R TYPE involves Reinforcing of the top chord angles. The specifying professional should be aware that an S TYPE is more economical and should be specified whenever possible. The tabulated values are the maximum allowable uniform loads. The S and I numbers shown in the Load Tables are the Elastic Section Modulus and Moment of Inertia of the extension (Section) number with which they are associated. Loads for extension lengths not explicitly given in Load Tables may be determined using linear interpolation between the load values given in adjacent columns. In cases where it is not possible to meet specific job requirements with a 2 1/2 inches deep R TYPE extension (refer to S and I values in the Extended End Load Table), the depth of the extension must be increased to provide greater load-carrying capacity. The S and R extension numbers are intended to be associated with Standard K-Series Sizes of matching Section Number. When possible, the extension number should be limited to no more than the Standard K-Series Section Number, for optimum economy. When TOP CHORD EXTENSIONS or EXTENDED ENDS are specified, the bracing requirements must be considered by the specifying professional. It should be noted that an R TYPE extension must be specified when building details dictate a 2 1/2 inch depth is required at the end of the extension. In the absence of specific instructions New Millennium may provide either TYPE.

68 Substitutes and Outriggers K-Series The following LRFD and ASD Load Tables for Substitutes, K-Series are based on the Steel Institute 44th Edition Standard Specifications - SJI substitutes are 2 1/2 inch deep sections intended for use in very short spans (less than 10 feet) where Open Web Steel s are impractical. They are commonly specified to span over hallways and short spans in skewed bays. Loads for span increments not explicitly given in Load Tables may be determined using linear interpolation between the load values given in adjacent spans. The BLACK figures in the LRFD Load Table gives the TOTAL safe factored uniformly distributed load- carrying capacity of 2.5K joist substitutes. The BLACK figures in the ASD Load Table gives the TOTAL safe unfactored uniformly distributed load-carrying capacity of 2.5K joist substitutes. The RED figures in the Load Table represent the unfactored uniform load which will produce an approximate joist substitute deflection of 1/360 of the span. This load can be linearly prorated to obtain the unfactored uniform load for supplementary deflection criteria (i.e. an unfactored uniform load which will produce a joist substitute deflection of 1/240 of the span may be obtained by multiplying the RED figure by 360/240). In no case shall the prorated, unfactored load exceed the unfactored TOTAL load-carrying capacity of the joist substitute as given in the ASD Load Table for 2.5 inch Simple Span Substitutes, K-Series. Minimum section properties shall be provided for the particular 2.5K designation specified even at shorter spans where the developed load capacity may exceed 550 plf (ASD) or 825 plf (LRFD).

69 Substitutes and Outriggers K-Series The following LRFD and ASD Load Tables for Outriggers, K-Series are based on the Steel Institute 44th Edition Standard Specifications - SJI substitutes may be used in an outrigger condition with the member overhanging one support as illustrated below, where a portion is the back span and the remainder is the cantilever or outrigger. substitutes used in this configuration are 2 1/2 inch deep sections. Loads for span increments not explicitly given in Load Tables may be determined using linear interpolation between the load values given in adjacent spans. The BLACK figures in the LRFD Load Table gives the TOTAL safe factored uniformly distributed load- carrying capacity of 2.5K joist outriggers. The BLACK figures in the ASD Load Table gives the TOTAL safe unfactored uniformly distributed load-carrying capacity in of 2.5K joist outriggers.

70 Standard LRFD and ASD Load Tables KCS s The following LRFD and ASD Load Tables for KCS joists are based on the Steel Institute 44th Edition Standard Specifications - SJI The figures in the following table give the MOMENT CAPACITY and SHEAR CAPACITY. The maximum uniformly distributed load capacity shall not exceed 825 plf for LRFD or 550 plf for ASD. A single concentrated load cannot exceed the shear capacity. Sloped parallel-chord KCS joists shall use the appropriate moment and shear capacity for the span as defined by the length along the slope. The approximate KCS joist self-weights shown in the table do not include accessories. The KCS joist designation is not used to establish bridging requirements. The Bridging Table Section Numbers given in the KCS Standard Load Table indicate the equivalent K-Series joist of the same depth to be used for determination of the number of bridging rows, the size of horizontal bridging, and the need for erection stability bridging. While the need for erection stability bridging (diagonal bridging with bolted connections at the chords and intersections), can be determined from the RED shaded portion of the Standard Load Table, Open Web Steel s, K-Series, for convenience the KCS Load Table also includes a column for erection stability bridging. Where the span of the KCS joist designation exceeds the span listed, the row of bridging nearest the joist midspan shall be erection stability bridging. Where NA is listed in the column, the KCS joist designation does not require bolted diagonal erection bridging regardless of span. Discover the easiest way to specify Steel s and Girders: 70

73 Standard LRFD Load Tables The following Load Tables indicating the safe factored uniformly distributed load-carrying capacities of LRFD K, LH and DLH--Series Steel s are based on the Steel Institute 44th Edition Standard Specifications - SJI The Load Tables apply to joists with either parallel chords or pitched top chords up to 1/2 inch per foot. If the pitch exceeds 1/2 inch per foot, the Load Tables do not apply. When top chords are pitched, the load-carrying capacities are determined by the nominal depth of the joists at the center of the span for single-pitched top chords and at ridge line for double-pitched top chords. Sloped parallel-chord joists shall use span as defined by the length along the slope. Loads for span increments not explicitly given in Load Tables may be determined using linear interpolation between the load values given in adjacent spans. The approximate joist weights given in the Load Tables may be added to the other building weights to determine the unfactored DEAD load. In all cases the factored DEAD load, including the joist self-weight, must be deducted from the TOTAL load to determine the factored LIVE load. The approximate joist weights do not include accessories. The BLACK figures in the Load Tables represent the TOTAL safe factored uniformly distributed load-carrying capacities. The TOTAL safe factored uniformly distributed load-carrying capacities of LRFD K-Series Steel s shall not exceed 825 plf for spans shorter than what is explicitly shown in the Load Tables. The maximum prorated RED load shall not exceed 550 plf (the TOTAL load-carrying capacity of the joist as given in the Standard ASD Load Tables for K-Series Steel s). *The safe factored uniform load for the spans shown in the SAFE LOAD Column is equal to (SAFE LOAD) / (span). The TOTAL safe factored uniformly distributed load-carrying capacity for spans less than those shown in the SAFE LOAD Column are given in the MAX LOAD Column. The RED figures in the Load Tables represent the unfactored uniform load which will produce an approximate joist deflection of 1/360 of the span. This load can be linearly prorated to obtain the unfactored uniform load for supplementary deflection criteria (i.e. an unfactored uniform load which will produce a joist deflection of 1/240 of the span may be obtained by multiplying the RED figures by 360/240). In no case shall the prorated unfactored load exceed the unfactored TOTAL load-carrying capacity of the joist as given in the Standard ASD Load Tables. To solve for an unfactored RED figure for spans shown in the SAFE LOAD Column (or lesser spans), multiply the unfactored RED figure of the shortest span shown in the Load Table by (shortest span shown in Load Table 0.33 feet)2 and divide by (actual span 0.33 feet)2. In no case shall the calculated unfactored load exceed the unfactored TOTAL load-carrying capacity of the joist as determined from the Standard ASD Load Tables. The approximate gross moment of inertia (not adjusted for shear deformation) of a standard joist listed in the Load Table may be determined as follows: Ij = (W)(L3)(10-6) in4, where W = RED figure in the Load Table and L = (span 0.33) in feet Where the joist span is in the RED SHADED area of the Load Table, the row of bridging nearest the mid span shall be diagonal bridging with bolted connections at chords and intersections. Hoisting cables shall not be released until this row of bolted diagonal bridging is completely installed. The RED SHADED area extends up through Where the joist span is in the BLUE SHADED area of the Load Table, all rows of bridging shall be diagonal bridging with bolted connections at chords and intersections. Hoisting cables shall not be released until the two rows of bridging nearest the third points are completely installed. The RED SHADED area starts after 60 0 and extends up through Where the joist span is in the GRAY SHADED area of the Load Table, all rows of bridging shall be diagonal bridging with bolted connections at chords and intersections. Hoisting cables shall not be released until all rows of bridging are completely installed.

84 Standard ASD Load Tables The following Load Tables indicating the safe uniformly distributed load-carrying capacities of ASD K, LH and DLH-Series Steel s are based on the Steel Institute 44th Edition Standard Specifications - SJI The Load Tables apply to joists with either parallel chords or pitched top chords up to 1/2 inch per foot. If the pitch exceeds 1/2 inch per foot, the Load Tables do not apply. When top chords are pitched, the load-carrying capacities are determined by the nominal depth of the joists at the center of the span for single-pitched top chords and at ridge line for double-pitched top chords. Sloped parallel-chord joists shall use span as defined by the length along the slope. Loads for span increments not explicitly given in Load Tables may be determined using linear interpolation between the load values given in adjacent spans. The approximate joist weights given in the Load Tables may be added to the other building weights to determine the DEAD load. In all cases the DEAD load, including the joist self-weight, must be deducted from the TOTAL load to determine the LIVE load. The approximate joist weights do not include accessories. The BLACK figures in the Load Tables represent the TOTAL safe unfactored uniformly distributed load-carrying capacities. The TOTAL safe uniformly distributed load-carrying capacities of ASD K-Series Steel s shall not exceed 550 plf for spans shorter than what is explicitly shown in the Load Tables. *The safe uniform load for the spans shown in the SAFE LOAD Column is equal to (SAFE LOAD) / (span). The TOTAL safe uniformly distributed load-carrying capacity for spans less than those shown in the SAFE LOAD Column are given in the MAX LOAD Column. The RED figures in the Load Tables represent the uniform load which will produce an approximate joist deflection of 1/360 of the span. This load can be linearly prorated to obtain the uniform load for supplementary deflection criteria (i.e. a uniform load which will produce a joist deflection of 1/240 of the span may be obtained by multiplying the RED figures by 360/240). In no case shall the prorated load exceed the TOTAL load-carrying capacity of the joist. To solve for a RED figure for spans shown in the SAFE LOAD Column (or lesser spans), multiply the RED figure of the shortest span shown in the Load Table by (shortest span shown in Load Table 0.33 feet) 2 and divide by (actual span 0.33 feet) 2. In no case shall the calculated load exceed the TOTAL load-carrying capacity of the joist. The approximate gross moment of inertia (not adjusted for shear deformation) of a standard joist listed in the Load Table may be determined as follows: Ij = (W)(L 3 )(10-6 ) in 4, where W = RED figure in the Load Table and L = (span 0.33) in feet Where the joist span is in the RED SHADED area of the Load Table, the row of bridging nearest the mid span shall be diagonal bridging with bolted connections at chords and intersections. Hoisting cables shall not be released until this row of bolted diagonal bridging is completely installed. The RED SHADED area extends up through Where the joist span is in the BLUE SHADED area of the Load Table, all rows of bridging shall be diagonal bridging with bolted connections at chords and intersections. Hoisting cables shall not be released until the two rows of bridging nearest the third points are completely installed. The BLUE SHADED area starts after 60 0 and extends up through Where the joist span is in the GRAY SHADED area of the Load Table, all rows of bridging shall be diagonal bridging with bolted connections at chords and intersections. Hoisting cables shall not be released until all rows of bridging are completely installed.

95 Weight Tables Load/Load LH-Series s The joists represented in the following Weight Tables are based on the Steel Institute 44th Edition Standard Specifications - SJI These Weight Tables are intended to be a tool to assist in the preliminary design and estimate for joists used in floors and roofs with high capacity loading requirements. All of the values are approximate and intended as a guide for the specifying professional. New Millennium will design for the specific loads of the designation at the required span, and the values for self-weight, moment of inertia, and w360 load may vary from the tabulated values the tabulated values are not design minimums or maximums. Load/ Load joist designations are not limited to only the combinations of load, depth, and span as shown in these tables. Interpolation can be used for approximate values when needed between the columns and rows of the table. The Weight Tables apply only to joists with parallel chords. The joist top chords are considered as being laterally supported by the deck and/or slab in accordance with the aforementioned specifications. The top (2) rows of figures provide the total uniform design load applied to the joist for LRFD (factored) or ASD (unfactored) loading. The row labeled WEIGHT is the approximate joist weight in pounds per linear foot. The rows labeled w360 are the uniform loads that will produce an approximate deflection of 1/360 of the span. Where the w360 load is equal to the Total Load, the actual w360 load is greater than the Total Load. The rows labeled Ix provide the approximate Moment of Inertia in inches 4 for the joist. The rows labeled Pbrg are the nominal horizontal force in pounds to be used to determine the required horizontal bridging angle size. s in the UN-SHADED areas require a 5 inch minimum bearing seat depth* and (1) row of standard horizontal bridging minimum. s in the RED SHADED areas require a 5 inch minimum bearing seat depth*, (1) row of bolted diagonal erection bridging and (1) row minimum, of standard horizontal bridging. s in the BLUE SHADED areas require a 5 inch minimum bearing seat depth* and (2) rows minimum, of standard horizontal bridging. s in the GREEN SHADED areas require a 7 1/2 inch minimum bearing seat depth and (2) rows minimum, of standard horizontal bridging. Example: Geometry Design Loads Depth plf ASD Total Load Span plf Live Load For this example the joist designation will be 26LH1800/1000 Entering the Weight Tables for a JOIST SPAN of 32, a JOIST DEPTH (in) of 26 and an ASD Total Load (plf) of 1800, the joist will have the following approximate design values/requirements: WEIGHT = 31.8 (plf) w360 = 1606 (plf) Ix = 1271 (in 4 ) (1) row minimum, of standard horizontal bridging sized for a bridging force Pbrg = 1178 pounds Minimum bearing seat depth = 5 *All joists to the right of the heavy BLUE line require a 7 1/2 inch minimum bearing seat depth.

107 Weight Tables Girders The Girders represented in the following Weight Tables are based on the Steel Institute 44th Edition Standard Specifications - SJI The following Weight Tables are also based on the use of 50 ksi maximum yield strength steel. These Weight Tables are intended to be a tool to assist in the preliminary design and estimate for Girders used in floors and roofs. All of the JOIST GIRDER WEIGHT values shown are approximate and intended as a guide for the specifying professional. New Millennium will design for the specific loads of the designation at the required span, and the values for self-weight may vary from the tabulated values the tabulated values are not design minimums or maximums. It is presumed that the designated kip load includes an allowance for the Girder self-weight, unless noted otherwise on the structural drawings. There are countless combinations of span, number of panels, kip loads, and Girder depths and the tables do not represent all available combinations. Interpolation can be used for approximate values when needed between the columns and rows of the table. The Weight Tables apply only to Girders with parallel chords. The Girder top chords are considered as being laterally supported by positive attachment of the supported steel joists to the Girder top chords. The top (2) rows of figures present the total PANEL POINT LOAD to be applied to the Girder at each joist location for LRFD (factored) or ASD (unfactored) loading. The JOIST GIRDER WEIGHT values shown in the tables are based on the PANEL POINT LOAD value including an allowance for an assumed Girder self-weight. Girders weighing up to 149 plf are anticipated to have chord angles of 6 x 6 or smaller and shall have a 7 1/2 inch minimum bearing seat depth. Girders weighing 150 plf or greater are considered high capacity Girders requiring chord angles of 8 x 8 and shall have a 10 inch minimum bearing seat depth. Example: Girder Geometry Design Loads Girder Depth kips ASD Total Load at each joist location Girder Span 50-0 Number of joist spaces 8 For this example the Girder designation will be 40G8N12K Entering the Weight Tables for a GIRDER SPAN of 50, JOIST SPACES of 8, a GIRDER DEPTH (in) of 40 and an ASD PANEL POINT LOAD (kips) of 12, the Girder will have the following approximate self-weight/requirements: JOIST GIRDER WEIGHT = 59 (plf) Minimum bearing seat depth = 7 1/2 Girder Weight Tables Standard Specifications Discover the easiest way to specify Steel s and Girders: Fire Resistance and OSHA
