3 Manufactured Wood is energy efficient Good news for a healthy planet! Wood is a good use for homes and light framing commercial applications that are built to house and office not only North America s people, but the people of our globalized world. Engineered wood is one step further ahead in supporting our effort in sustaining one of the world s largest natural resources. Engineered wood products use less wood to get more out of the wood that is remanufactured, thus supporting our ever-sensitive environment. Engineered wood products comprise six primary categories: Laminated Veneer Lumber (LVL): Used in studs, headers, rim board, beams, columns, and in roof and floor truss applications, where applicable. Manufactured Wood I Beams: Used as floor joists and as rafters in roof framing. Finger Joint Lumber: Made by gluing together short pieces of lumber that might otherwise become waste. Finger joint lumber is commonly used in wall stud applications. Glulaminated Beams: Made of large, dimensional lumber glued together to sustain larger load applications for both short- and large-span conditions. Manufactured Trusses: Engineered by placing and assembling 2x4 and 2x6 lumber members in a predetermined manner to help sustain high loads for various span conditions in floor and roof framing applications. Oriented Strand Board (OSB) Floor and Roof Panels: Formed with small wood fiber chip members glued together under heat and pressure to a predetermined thickness and dimension. OSB panels are commonly used as roof and floor sheathing panels. Integri- page 3

5 Safety & Construction Precautions Installation Walking on the joists should not be permitted until they are properly braced. All hangers, rim boards, rim joists and blocking at the end supports of the joists must be installed and nailed properly. during installation, a minimum of 1 x 4 temporary bracing is required. Bracing members should be spaced at 8 0 o.c. and nailed to each joist with two 8d nails (10d box nails if bracing thickness exceeds 1 ). lap bracing ends and anchor them to temporary or permanent sheathing nailed to the first 4 of joists at the end of the bay or a braced end wall. Storage Do not cut, drill, or notch flanges. The ends of cantilevers must be temporarily braced on both the top and bottom flanges. Never overload sheathed joists with loads that exceed design loads. Only remove the bracing as the sheathing is attached. Engineered wood products should be used in dry conditions only. When stacking construction material, stack only over beams or walls, NOT on unsheathed joists. These are general recommendations and in some cases, additional precautions may be required. Storage & Handling installation guidelines from Integrity will be included with every shipment of trademarked Integri-s to job sites. Store bundles upright on a smooth, level, well drained supportive surface. Always stack and handle I-joists in the upright position only. Bundles should not be in contact with the ground. Place 2x or LVL spacers (at a maximum of 10 apart) between bundles and the ground, and bundles stored on top of one another. Bundles should remain wrapped, strapped and protected from the weather until time of installation. system performance Traditionally, floor vibration has not been an issue with a well-designed and constructed floor. The model code-required serviceability deflection requirements of span/360 for live load and span/240 for total load have long served to keep codeconforming floors stiff enough to minimize vibration-related problems. These deflection requirements were based on the use of traditional lumber framing and prevailing architectural norms. Spans in traditional lumber-framed structures seldom exceeded feet. With engineered wood products, however, designers are no longer limited by the capacities and lengths of traditional lumber structural elements. Spans unheard of just a few years ago are now common with engineered wood products. The traditional deflection limits may no longer be appropriate for the longer spans made possible by engineered wood products. For this reason, APA has voluntarily adopted a live load deflection criteria that is 33% stiffer than that required in the current model building codes. This deflection criteria was selected for increase because vibration loads are caused by transient or live loads, most often by people moving about the floor itself. By increasing the stiffness of the floor using span/480 requirements instead of the more traditional span/360 the vibrations caused by a thundering herd of youngsters can be more easily tolerated. Designing the ideal floor is not, however, an exact science. Because one of the benefits of a wood floor is its ability Handling All handling of joists with a forklift or crane should be done carefully. s should remain vertical during handling. Avoid excessive bowing during all phases of handling and installation (i.e. measuring, sawing, or placement). damage may result if the joist or beam is twisted or a load is applied to it while it s lying flat. Never use or field repair a damaged I-joist. to cushion footfalls, it is not desirable to make every floor overly stiff. As usual, a one-size solution does not fit all. The selection of span/480 as a serviceability requirement is a compromise. It provides a substantial decrease in floor vibration with a minimal cost penalty without making the floor so stiff that comfort is compromised. Researchers have proposed a number of additional methods that can be used to reduce floor vibration even further. These methods include: Gluing the wood structural panel floor to the Integri-s Attaching wood structural panels or gypsum board to the bottom of the I-joists decreasing the I-joist spacing by one increment based on allowable span Using full-depth blocking at regular intervals between all of the I-joists over the entire floor Adding concrete topping over the floor sheathing By far the most practical and most economical way to further increase the stiffness of your floor when using Integri-s is to select the most economical joist from our allowable span tables and then maintain the same joist designation but upgrade to the next net depth.

Both requirements must be satisfied. When no value is shown in a column, load governs. 3. Web stiffeners are required at all supports for 22 and 24 joists. See Web Stiffener Requirements on page 57 for more details Notes: 1. Table values apply to uniformly loaded floor joists. 2. Span is measured to the center of each support. 3. The values in the columns are based on an L/240 total load deflection limit. Building codes typically require L/360 for live load. Experience has shown that a live load deflection limit of at 40 psf for residential floors does a better job than L/360 of meeting most performance expectations. 4. Table values do not account for stiffness added by glued or nailed sheathing. 5. Provide at least 1C\v of bearing length at end supports and 3Z\x at intermediate supports. 6. Provide lateral restraint at supports (e.g. blocking panels, rim board) and along the compression flange of each joist (e.g. floor sheathing, gypsum board ceiling). 7.

Check the local building code for deflection requirements. Table values are limited to L/180 at total load and L/240 at live load. 2. Choose the appropriate load duration category 100% for heavy snow, 115% for snow or 125% for non-snow. When in doubt, consult the local building department. 3. Choose the appropriate live and dead load combination and a joist spacing. 4. Scan down the spacing column to find a span that exceeds the horizontal design span and the minimum connection required at each support. 5.

Table values apply to uniformly loaded roof joists that are sloped at least ¼ in Span is measured on the horizontal from face to face of supports. 3. Table values do not account for stiffness added by glued or nailed sheathing. 4. Provide at least 1¾ of bearing length at end supports and 3½ at intermediate supports. 5. The numbers in parentheses refer to the minimum connection required at each support. (1) Beveled plate and two nails (205 lbs. lateral 125%), or joist hanger (2) Beveled plate and four nails (410 lbs. lateral 125%), or (3) (3) Gussets at high support (1620 lbs. lateral 125%), birdsmouth cut at low support, or (4) (4) Strap (1640 lbs. lateral 125%) or pair of twist straps (950 lbs. lateral capacity 125%) at high support, birdsmouth cut at low support 6.

Table values apply to uniformly loaded roof joists that are sloped at least ¼ in Span is measured on the horizontal from face to face of supports. 3. Table values do not account for stiffness added by glued or nailed sheathing. 4. Provide at least 1¾ of bearing length at end supports and 3½ at intermediate supports. 5. The numbers in parentheses refer to the minimum connection required at each support. (1) Beveled plate and two nails (190 lbs. lateral 115%), or joist hangers at end supports (2) Beveled plate and four nails (380 lbs. lateral 115%) at intermediate supports, two nails or joist hangers at end supports 6. Provide lateral restraint at supports (e.g. blocking panels, rim board) and along the compression flange of each joist (e.g. roof sheathing, gypsum board ceiling). 7. Use sizing software or consult a professional engineer to analyze conditions outside the scope of this table (e.g. different bearing conditions, concentrated loads) or for multiple span joists if the length of any span is less than half the length of an adjacent span.

Table values apply to uniformly loaded roof joists that are sloped at least ¼ in Span is measured on the horizontal from face to face of supports. 3. Table values do not account for stiffness added by glued or nailed sheathing. 4. Provide at least 1¾ of bearing length at end supports and 3½ at intermediate supports. 5. The numbers in parentheses refer to the minimum connection required at each support. (1) Beveled plate and two nails (205 lbs. lateral 125%), or joist hangers at end supports (2) Beveled plate and four nails (410 lbs. lateral 125%) at intermediate supports, two nails or joist hangers at end supports 6. Provide lateral restraint at supports (e.g. blocking panels, rim board) and along the compression flange of each joist (e.g. roof sheathing, gypsum board ceiling). 7.

Table values apply to uniformly loaded roof joists. 2. Span is measured to the center of each support. 3. Roofs must be sloped at least ¼ in 12 to assure drainage. 4. Table values do not account for stiffness added by glued or nailed sheathing. 5. Provide at least 1¾ of bearing length at end supports and 3½ at intermediate supports. 6. Provide lateral restraint at supports (e.g. blocking panels, rim board) and along the compression flange of each joist (e.g. roof sheathing, gypsum board ceiling). 7. Use sizing software or consult a professional engineer to analyze conditions outside the scope of this table (e.g. different bearing lengths, concentrated loads) or for multiple span joists if the length of any span is less than half the length of an adjacent span. How to use roof Load Tables 1. Choose a joist spacing and convert the live and total design loads specified in pounds per square foot (psf) to joist loads in pounds per lineal foot (plf). Spacing (ft) x Design Load (psf) = Load (plf). Load (PSF) Spacing Design Load (psf) (inches) (feet) Check the local building code for deflection requirements. Building codes typically require L/180 for total load and L/240 for live load. The values in the columns are based on L/ Choose a span. Use the horizontal span dimension from the building plans for roofs that slope up to 2 in 12. For roof slopes greater than 2 in 12, multiply the horizontal dimension by the appropriate factor from the table below. Slope 2Z\x in 12 3 in 12 3Z\x in 12 4 in 12 4Z\x in 12 5 in 12 6 in 12 7 in 12 8 in 12 9 in in in in 12 Factor Choose a load duration category 100% for heavy snow, 115% for snow and 125% for non-snow. When in doubt, consult the local building department. 5. Scan across the Span row to find a joist size with sufficient and applicable load capacities. Both requirements must be satisfied. When no value is shown in a column, load governs. 6. Sloping joists must be fastened to each support to resist a sliding force equal to: 0.5XWL at end supports and 1.25XWL at intermediate supports X X where X = roof slope in 12, L = span (ft) and W = S LL+ DL X , where S = joist spacing (ft), LL = live load (psf) and DL = dead load (psf) Web stiffeners are required at all supports for 22 and 24 joists.

Check the local building code for deflection requirements. Table values are limited to L/180 at total load and L/240 at live load. 2. Choose the appropriate load duration category 100% for heavy snow, 115% for snow or 125% for non-snow. When in doubt, consult the local building department. 3. Choose the appropriate live and dead load combination, roof slope and a joist spacing. 4. Scan down the spacing column to find a span that exceeds the horizontal design span and the minimum connection required at each support. 5. Scan to the left from that span to determine the joist size required. 6. Web stiffeners are required at all supports for 22 and 24 joists. See Web Stiffener Requirements on page 57 for more details. page 46 Integri-

51 MSR Flange Integri- Series Roof Loads How to Use Roof Load Tables 1. Choose a joist spacing and convert the live and total design loads specified in pounds per square foot (psf) to joist loads in pounds per lineal foot (plf). Spacing (ft) x Design Load (psf) = Load (plf). Load (PSF) Spacing Design Load (psf) (inches) (feet) Check the local building code for deflection requirements. Building codes typically require L/180 for total load and L/240 for live load. The values in the columns are based on L/ Choose a span. Use the horizontal span dimension from the building plans for roofs that slope up to 2 in 12. For roof slopes greater than 2 in 12, multiply the horizontal dimension by the appropriate factor from the table below. Slope 2Z\x in 12 3 in 12 3Z\x in 12 4 in 12 4Z\x in 12 5 in 12 6 in 12 7 in 12 8 in 12 9 in in in in 12 Factor Choose a load duration category 100% for heavy snow, 115% for snow and 125% for non-snow. When in doubt, consult the local building department. 5. Scan across the Span row to find a joist size with sufficient and applicable load capacities. Both requirements must be satisfied. When no value is shown in a column, load governs. 6. Sloping joists must be fastened to each support to resist a sliding force equal to: 0.5XWL at end supports and 1.25XWL at intermediate supports X X where X = roof slope in 12, L = span (ft) and W = S LL+ DL X , where S = joist spacing (ft), LL = live load (psf) and DL = dead load (psf) Web stiffeners are required at all supports for 22 and 24 joists.

57 Web Stiffener Requirements Web stiffeners are pairs of small blocks, cut from panels or 2x4s, that are nailed to the joist web to stiffen a deep web, increase reaction capacity or accommodate a special connector. Web stiffeners are not required when joists are sized by means of the tables in this guide, with the following exceptions: 1. Web stiffeners are required at the ends of joists set in hangers that are not deep enough to laterally support the top flanges of the joists. Refer to the hanger manufacturer s installation instructions. 2. Web stiffeners are required to accommodate special connector nailing requirements. Refer to the connector manufacturer s installation instructions. 3. Web stiffeners are required at birdsmouth cuts at the low end supports of sloped joists. 4. Web stiffeners are required at all supports on 22- and 24-inch joists. When joists are sized by means of sizing software, or otherwise engineered for an application, web stiffeners are required as follows: 1. Web stiffeners are required for high reactions at supports. Refer to ESR Web stiffeners are required under concentrated loads applied to the tops of joists between supports, or along cantilevers beyond the support, when the concentrated load exceeds 1500 pounds. figure B I- Web Stiffener Requirements Number of Web Stiffener Nails Required 24 & & & Less Intermediate Support All Other Conditions Concentrated Load > 1500 lbs.

58 Web Hole Specifications Duct Holes Minimum Distance D From Any Support to the Centerline of the Hole Series / (depths to 20 ) 90 (depths to 20 ) Duct Hole Width Span (ft) For depths greater than 20, use beam sizing software to size and locate duct holes. See GENERAL NOTES on this page. General Notes 1. Table values apply to joists sized by means of the load or span tables in this publication. Use beam sizing software for a more precise analysis or to analyze conditions outside of the scope of these tables. 2. Web holes may be located anywhere between the joist flanges. Leave at least Z\, inch clearance between the edges of holes and the flanges. 3. do not cut rectangular holes, or round holes larger than 1Z\x inch diameter, in cantilevers. 4. The horizontal clearance between the edges of adjacent holes must be at least twice the diameter (or longest side) of the larger hole. Exception: A 1Z\x inch diameter hole may be drilled anywhere in the web. Provide at least 3 inches of horizontal clearance from adjacent holes of any size. 5. 1Z\x inch diameter holes are factory-scored in the web at 16 inches on center. Never drill, cut or notch the flange, or over-cut the web. Holes in webs should be cut with a sharp saw. For rectangular holes, avoid over cutting the corners, as this can cause unnecessary stress concentrations. Slightly rounding the corners is recommended. Starting the rectangular hole by drilling a 1 diameter hole in each of the 4 corners and then making the cuts between the holes is another good method to minimize damage to I-joists. page 58 Integri-
