Moment, Shear and Reaction Capacity values are for normal load duration and may be adjusted according to code. 2. When calculating deflection, both bending and shear deformation must be determined as follows: For simple span, uniform load: Δ = 22.5wL 4 + wl 2 Where: Δ = deflection in inches EI = bending stiffness from table El K w = uniform load in plf K = shear stiffness from table L = design span in feet 3. The Moment capacity shall not be increased by any code-allowed repetitive member use factor. 4. These design values are based on the product being used in a dry, well ventilated environment where the moisture content will not exceed 16% - such as in most covered structures. These products are intended to resist the effects of moisture on structural performance from normal construction delays but are not intended for permanent exposure to the weather.

Clinch nails where possible. NOTES: 1. Web stiffeners, when required, must be installed in pairs one to each side of the web. Web stiffeners are always required for the Bird s Mouth roof bearing detail. 2. Web stiffeners should be cut to fit between the flanges of the I-Joist, leaving a minimum 1/8" gap (1" maximum). At bearing locations, the stiffeners should be installed tight to the bottom flange with the gap to the top flange. At locations of concentrated loads, the stiffeners should be installed tight to the top flange with the gap to the bottom flange. 3. Web stiffeners should be cut from APA-Rated OSB (or equal). 2X lumber is permissible. Do NOT use 1x lumber as it tends to split. 4. Web stiffeners should be the same width as the bearing surface, with a minimum of 3-1/2". 5. See Web Stiffener Requirements table above for minimum stiffener thickness, maximum stiffener height and required nailing. 2

Floor Tables 1. Select the appropriate table based on the project design loads. 2. For simple spans, select the L/480 or L/360 section of that table, as required. For continuous spans, select the section with or without web stiffeners, as needed. 3. Find a span that meets or exceeds the design span. 4. Read the corresponding joist depth and spacing. Caution: For floor systems that require both simple span and continuous span joists, it is a good idea to check both before selecting a joist. Some conditions are controlled by continuous span strength rather than simple span deflection.

The spans listed are the clear distance between supports. 2. The spans are based on uniform loads only. 3. These tables reflect the additional stiffness provided by 23/32 OSB APA-Rated Sheathing (48/24) or APA-Rated Sturd-I-Floor (24" oc), or equivalent, glued and nailed to the top flange of the joists. 4. Live load deflection has been limited to L/480 or L/360 as indicated in the tables above (L/480 only for continuous spans). 5. Total deflection has been limited to L/240. Those spans that exceed 3/4" of total deflection are shown in bold. 6. The spans are based on the minimum required bearings as listed on page 2. ADDITIONAL NOTES: 1. Web stiffeners are not required for any of the spans listed in the Simple tables. Web stiffeners are only required for the Continuous tables in the With Web Stiffeners section. A - indicates that there is no increase in span through the use of web stiffeners. Web fillers are required for joists seated in hangers that do not laterally support the top flange. 2. L/360 is the minimum deflection criteria allowed per code, which allows the maximum amount of deflection in the floor. 3. The design of continuous spans is based on the longest span. The shortest span must not be less than 50% of the longest span. 4. These spans are not evaluated for vibration. 5. Bridging, blocking, a direct-applied ceiling and/or bottom-flange bracing, though not required for vertical load capacity, can improve floor vibration and bounce. 6. For conditions not shown, use the Uniform Floor Load (PLF) tables or contact your LP Engineered Wood Products distributor for assistance. 3

Uniform Floor Load (PLF) Tables: Simple s 1. Select the span required. 2. Compare the design total load to the Total Load column. Where two numbers are shown, the first number represents the Total Load capacity without web stiffeners. The second number represents the Total Load capacity with stiffeners. (See Additional Notes below.) 3. Compare the design live load to the appropriate Live Load column. 4. Select a product that exceeds both the design total and live loads. 5. Specify web stiffeners as dictated by the Total Load column. EXAMPLE: An I-Joist has the simple clear span of -6", supporting 50 psf Floor Load and 25 psf Dead Load, spaced 24" oc. Select the shallowest joist that satisfies an L/600 live load deflection limit. 1. Design Total Load = (50 + 25) * (24 / 12) = 150 plf. Design Live Load = 50 * (24 / 12) = 100 plf. 2. Select the row corresponding to a span. 3. Use the 18" LPI 56: Total Load = 196 plf and the Live Load at L/600 = 102 plf. NOTE: Web stiffeners required at both end supports.

The values are based on uniform loads of standard duration. 3. These tables assume that the joist is NOT a repetitive member, therefore load sharing has not been applied. Also, the deflection values do not reflect any additional stiffness due to composite action. 4. Total deflection has been limited to L/240. Long term deflection (creep) has NOT been considered. 5. These tables assume full lateral support of the compression flange. Full support is considered to be a maximum unbraced length of 24". 6. The values are based on the minimum required bearings as listed on page 2. ADDITIONAL NOTES: 1. The values represent the capacity of the joist in pounds per lineal foot (plf) of length. 2. The designer must check both the Total Load and the appropriate Live Load columns. 3. To design for a double I-Joist, the values in these tables can be doubled, or the design loads on the joist may be halved to verify the capacity of each ply. The capacity is additive. 4. Web stiffeners are not required where only one value is shown for Total Load or when the design total load does NOT exceed the first value in the Total Load column where two values are given. Web stiffeners ARE required at both end supports if the design total load exceeds the first value (capacity without stiffeners) but does not exceed the second value (capacity with stiffeners). Web fillers are required for joists seated in hangers that do not laterally support the top flange or for hangers that require nailing into the web. 5. Where the Live Load is blank, the Total Load governs the design. 6. Do not use a product where designated - without further analysis by a professional engineer. 4

The design of continuous spans is based on the longest span. The shortest span must not be less than 50% of the longest span. 2. The values are based on uniform loads only. 3. These tables assume that the joist is NOT a repetitive member, therefore load sharing has not been applied. Also, the deflection values do not reflect any additional stiffness due to composite action. 4. Total deflection has been limited to L/180. Long term deflection (creep) has NOT been considered. 5. These tables assume full lateral support of the compression flange. Full support is considered to be a maximum unbraced length of 24". 6. The values are based on the minimum required bearings as listed on page 2. ADDITIONAL NOTES: 1. The values represent the capacity of the joist in pounds per lineal foot (plf) of length. 2. The designer must check the appropriate Total Load column and the Live Load column. 3. For roofs with a slope of 2:12 or greater, the horizontal span must be multiplied by the appropriate slope adjustment factor from the table at the bottom of this page. 4. To design for a double I-Joist, the values in these tables can be doubled, or the design loads on the joist may be halved to verify the capacity of each ply. The capacity is additive.

Web stiffeners are not required where only one value is shown for Total Load or when the design total load does NOT exceed the first value in the Total Load column where two values are given. Web stiffeners ARE required at interior supports if the design total load exceeds the first value (capacity without stiffeners) but does not exceed the second value (capacity with stiffeners). Additionally, if the second value is marked *, web stiffeners are required at all supports. Web fillers are required for joists seated in hangers that do not laterally support the top flange or for hangers that require nailing into the web. 6. Where the Live Load is blank, the Total Load governs the design. 7. To design for a live load limit of L/360, L/480 or L /600, use the Uniform Floor Load tables. 8. Do not use a product where designated - without further analysis by a professional engineer.

The hole locations listed above are valid for floor joists supporting only uniform loads as follows: For joists 16" deep and less, the total uniform load must not exceed 130 plf (e.g., 40 psf Live Load and a 25 psf Dead Load, spaced up to 24" oc). The uniform dead load must be at least 10 plf. For joists greater than 16" deep, the total uniform load must not exceed 190 plf (e.g., 50 psf Live Load, 25 psf Dead Load with a 20 psf Partition Load, spaced up to 24" oc). The uniform dead load must be at least 25 plf. An additional concentrated safe load of 2000 lbs acting over 6.25 ft 2 (2.5' x 2.5') has also been included. 2. Hole location is measured from the inside face of bearing to the center of a circular hole, from the closest support. 3. Clear has NOT been verified for these joists and is shown for informational purposes only! Verify that the joist selected will work for the span and loading conditions needed before checking hole location. 4. Maximum hole depth for circular holes is Joist Depth less 4", not to exceed 14", except the maximum hole depth is 6" for 9-1/2", and 8" for 11-7/8" LP I-Joists. 5. Holes cannot be located in the span where designated -, without further analysis by a professional engineer. NOTES: 1. CUT HOLES CAREFULLY! DO NOT OVERCUT HOLES! DO NOT CUT JOIST FLANGES! 2. Holes may be placed anywhere within the depth of the joist. A minimum 1/4" clear distance is required between the hole and the flanges. 3. Round holes up to 1-1/2" diameter may be placed anywhere in the web. 4. Perforated knockouts may be neglected when locating web holes. 5. Holes larger than 1-1/2" are not permitted in cantilevers without special engineering. 6. Multiple holes must have a clear separation along the length of the joist of at least twice the length of the larger adjacent hole, or a minimum of 12" center-to-center, whichever is greater. 7. Multiple holes may be spaced closer provided they fit within the boundary of an acceptable larger hole. Example: two 3" round holes aligned parallel to the joist length may be spaced 2" apart (clear distance) provided that a 3" high by 8" long rectangle or an 8" diameter round hole are acceptable for the joist depth at that location and completely encompass the holes. 8. Not all series are available in all depths. Check availability with a local LP Engineered Wood Products distributor. 9. Locating holes in joists with spans exceeding those in the tables or larger holes, greater uniform loads or non-uniform loads, and closer proximity to supports and other holes may be possible with analysis using LP s design software. Please contact your local LP Engineered Wood Products distributor for more information. 8

The hole locations listed above are valid for floor joists supporting only uniform loads as follows: For joists 16" deep and less, the total uniform load must not exceed 130 plf (e.g., 40 psf Live Load and a 25 psf Dead Load, spaced up to 24" oc). The uniform dead load must be at least 10 plf. For joists greater than 16" deep, the total uniform load must not exceed 190 plf (e.g., 50 psf Live Load, 25 psf Dead Load with a 20 psf Partition Load, spaced up to 24" oc). The uniform dead load must be at least 25 plf. An additional concentrated safe load of 2000 lbs acting over 6.25 ft 2 (2.5' x 2.5') has also been included. 2. Hole location is measured from the inside face of bearing to the nearest edge of a rectangular hole, from the closest support. 3. Clear has NOT been verified for these joists and is shown for informational purposes only! Verify that the joist selected will work for the span and loading conditions needed before checking hole location. 4. Maximum hole depth for rectangular holes is Joist Depth less 4", not to exceed 14", except the maximum hole depth is 6" for 9-1/2", and 8" for 11-7/8" LP I-Joists. Maximum hole width for rectangular holes is 18". Where the Maximum Hole Dimension for rectangular holes exceeds the maximum hole depth, the dimension refers to hole width, and the hole depth is assumed to be the maximum for that joist depth. 5. Holes cannot be located in the span where designated -, without further analysis by a professional engineer. NOTES: 1. CUT HOLES CAREFULLY! DO NOT OVERCUT HOLES! DO NOT CUT JOIST FLANGES! 2. Holes may be placed anywhere within the depth of the joist. A minimum 1/4" clear distance is required between the hole and the flanges. 3. Round holes up to 1-1/2" diameter may be placed anywhere in the web. 4. Perforated knockouts may be neglected when locating web holes. 5. Holes larger than 1-1/2" are not permitted in cantilevers without special engineering. 6. Multiple holes must have a clear separation along the length of the joist of at least twice the length of the larger adjacent hole, or a minimum of 12" center-to-center, whichever is greater. 7. Multiple holes may be spaced closer provided they fit within the boundary of an acceptable larger hole. Example: two 3" round holes aligned parallel to the joist length may be spaced 2" apart (clear distance) provided that a 3" high by 8" long rectangle or an 8" diameter round hole are acceptable for the joist depth at that location and completely encompass the holes. 8. Not all series are available in all depths. Check availability with a local LP Engineered Wood Products distributor. 9. Locating holes in joists with spans exceeding those in the tables or larger holes, greater uniform loads or non-uniform loads, and closer proximity to supports and other holes may be possible with analysis using LP s design software. Please contact your local LP Engineered Wood Products distributor for more information. 9

LP OSB Rim Board An Exact Match To Our LP I-Joist Depths LP OSB Rim Board is a strong, cost-effective complement to LP s engineered floor system. LP I-Joists and LP LVL beams offer many advantages over conventional framing. Now LP OSB Rim Board completes LP s floor system package with an easy, reliable way to finish off floor and roof installations. Quick and convenient, LP OSB Rim Board is precision cut to match our 9-1/2", 11-7/8", 14" and 16" LP I-Joist depths. - 0" and - 0" lengths mean your LP engineered floor system goes together even faster. Eliminates inaccuracies and time involved in ripping plywood rim. High load capacity means squash blocks are unnecessary on most multi-story applications. Flat surface means easy fastening for siding. LP OSB Rim Board is manufactured using predominantly fast growing trees, a renewable resource that leaves our old-growth forests for future generations to enjoy. Fastener Values (1) Nail Values: For nails installed into the wide face of LP OSB Rim Board, use the values for Douglas Fir lumber (Specific Gravity, SG=0.50) per the National Design Specification for Wood Construction. To allow for the 16d nails from the sole plate above into the top edge of the rim, the deck nailing must be at least 6" oc and the 16d nails must be spaced in accordance with the prescriptive requirements of the code. (2) Bolt & Lag Screw Values: For 1/2" diameter through-bolts and lag screws installed in the wide face and loaded in single shear, perpendicular-to-grain, the allowable capacity is: 300 lbs. for 1" rim board 350 lbs. for 1-1/8" rim board Lag screws must be at least 4" long. Design value for horizontal shear for APA rim board: 180 plf. This value is applicable to wind or seismic loads and shall not be adjusted for load duration. 8d (box or common) or 10d box nails, one at top, one at bottom of each I-Joist INSTALLATION MAXIMUM LOAD d 16" 16"<d 24" 1" 3300 plf 1650 plf 1-1/8" 4400 plf 3000 plf RIM TO JOIST CONNECTION NOTE: Rim board must be connected to wall plate and floor deck.
