Properties evaluated:  Structural  Sound ratings  Fire-resistance ratings 2.0 USES TJI joists are prefabricated wood I-joists used as floor joists, roof rafters, blocking panels and rim joists, to support code-required loads. Prefabricated wood I-joists described in this report comply with Section 2303.1.2 of the IBC, for allowable stress design; and Section R502.1.4 of the IRC. 3.0 DESCRIPTION 3.1 General: TJI joists are prefabricated wood I-joists having wood or wood-based flanges and Performance Plus® oriented strand board (OSB) webs. Either the top and bottom flanges are parallel, forming a constant-depth joist; or the top flange has a single taper, forming a variable-depth joist. The web panels have the face grain oriented vertically, and the web-to-web connection is either butt jointed or serrated and glued to form a continuous web. The web-to-flange connection is a proprietary tongue-and- groove glued joint. Refer to Table 1 for TJI joist series and material descriptions. The TJI L65, TJI L90, TJI H90, TJI HD90, and TJI HS90, may also be trademarked as: TJI L460, TJI L560, TJI H560, TJI HD560, and TJI HS560, respectively. 3.2 Material Specifications: 3.2.1 Flanges: Flange material is either Microllam® laminated veneer lumber (LVL), TimberStrand® laminated strand lumber (LSL) or machine stress rated lumber (MSR). Microllam LVL and TimberStrand LSL are recognized in evaluation report ESR-1387. Table 1 of this report specifies flange widths and depths. Flange material and grades are as specified in the quality control manual that contains Weyerhaeuser manufacturing standards. 3.2.2 Webs: Web material is Performance Plus® OSB conforming to DOC Voluntary Product Standard PS2, Exposure 1, along with further requirements set forth in the quality-control manual that contains Weyerhaeuser manufacturing standards.

Page 1 of 24 09/07/17 ESR-1153 | Most Widely Accepted and Trusted Page 2 of 24 National Design Specification for Wood Construction® (NDS). 4.2 Design Values: Table 3 specifies reference design moments, reactions, vertical shear forces, and joist stiffness (EI). Reference design reactions are based on minimum bearing lengths of 13/4 inches, 2 1 /2 inches and 31/2 inches (45, 64 and 89 mm), for simple spans; and 31/2, 51/4 and 7 inches (89, 133 and 178 mm) at intermediate support points for continuous spans. When joists are used as multiple span members, the calculated shear, used for design at the intermediate support, may be reduced by the percentage determined from the following formula and limited to the depths shown in Table 4: R = W ÷ Kred ≤ 18% where: Kred = V12 ÷ 100. R = The percent reduction. V12 = The reference design shear for an 117/8-inch- deep (302 mm) joist (pounds). W = The uniform load (plf). The reference design shear at the interior supports of multiple-span-member TJI joists up to 12 inches (305 mm) deep, used in residential floor construction, is permitted to be increased by 10 percent. This increase in reference design shear does not apply to the design shear at the ends of the joists. 4.3 Fasteners: Reference lateral and withdrawal design loads for fasteners, installed parallel or perpendicular to Microllam LVL or TimberStrand LSL flange glue lines, must be determined in accordance with ESR-1387 and the applicable code. Reference lateral and withdrawal design loads for fasteners installed into TJI joist sawn lumber flanges must be designed using the applicable code and a specific gravity of 0.42, such as for spruce-pine-fir. Allowable nail spacings for TJI joist diaphragm applications must be as specified in Sections 4.14 and 4.15, and Table 2. For nondiaphragm applications: 1. The spacing of fasteners installed into the face grain of Microllam LVL or TimberStrand LSL flanges must be greater than or equal to the closest permitted on-center spacing prescribed by the code for fasteners installed in sawn lumber. The spacing of fasteners installed into the edge grain of Microllam LVL or TimberStrand LSL flanges must be greater than or equal to the closest permitted on-center spacing requirements detailed in ESR-1387. 2. The spacing of fasteners installed into TJI joist sawn lumber flanges must be as prescribed by the code for fasteners installed in sawn lumber. The allowable lateral load capacity of 10d by 11/2-inch-long (38 mm) common nails used to connect minimum No. 18 gage [0.048 inch (1.2 mm) base- metal thickness] metal straps or tension-ties, recognized in a current ICC-ES evaluation report, to TJI joist flanges, in conformance with Figure 6 of this report, is 112 pounds-force (498 N) per nail. 4.4 Web Stiffeners: Web stiffener requirements for reactions and concentrated loads are noted in Table 3 and Figure 1. 4.5 Lateral Support: TJI joist compression flanges with widths less than 2.3 inches (58 mm) require lateral support every 18 inches (457 mm) on center. TJI joist compression flanges with widths equal to or greater than 2.3 inches (58 mm) require lateral support every 24 inches (610 mm) on center. Each connection must be capable of transmitting a 75-pound- force (334 N) horizontal load. All TJI joist ends require restraint to prevent rollover. Code-prescribed methods of lateral restraint specified for sawn lumber are acceptable. Bridging is not required for floor and roof TJI joist applications. 4.6 Holes in TJI Joist Web: The tables in Figures 2 and 3 specify allowable sizes and location of round, square and rectangular holes in the TJI joist webs. TJI joists with holes located in the web in accordance with Figures 2 and 3 are permitted to be used in the fire-resistive-rated Assemblies B, C, D, E, F, G and H described in Figures 4B through 4H. 4.7 Duration of Load: Adjustments for duration of load, in accordance with Part 2.3.2 of the NDS, apply to the TJI joists and their fastenings. 4.8 In-service Moisture Conditions: TJI joists must be installed in dry service conditions, where the moisture content in-service is less than 16 percent, as in most covered structures. 4.9 Repetitive-member Use: The repetitive-member use factor applicable to the resistive moment capacities listed in Table 3 is limited to 1.0. 4.10 Member Spans: TJI joist spans must be determined in accordance with Part 3.2.1 of the NDS. Vertical shear calculations must include all loads within the span from face to face of supports. 4.11 Deflection: Deflection of simple span TJI joists with either uniform load or a concentrated load at midspan is determined using the formulas in the footnotes to Table 3. 4.12 Blocking Panels: Bearing walls perpendicular to and supported by TJI joists at the end or intermediate supports, or both, require full-depth blocking. TJI joists up to and including 16 inches (406 mm) in depth, when used as blocking panels, have a maximum vertical load transfer capacity of 2,100 plf (30 645 N/m). TJI joists over 16 inches (406 mm) and up to and including 20 inches (508 mm) in depth, when used as blocking panels, have a maximum vertical load transfer capacity of 1,550 plf (22 620 N/m). 4.13 Rim Joists: TJI joists having depths of up to and including 16 inches (406 mm) may be used as rim joists and boundary members of horizontal wood structural diaphragms. The joists have a maximum vertical load transfer capacity of 2,100 plf (30,645 N/m). TJI joists used as rim joists must be laterally supported at the top and continuously supported at the bottom, and the gravity loads must be uniformly applied along the top. Other loading and support 09/07/17 ESR-1153 | Most Widely Accepted and Trusted Page 3 of 24 conditions must be investigated and approved by a design professional. 4.14 TJI Joists as Prescriptive Diaphragm Framing Members: TJI joists are permitted as framing members in prescriptive floor and roof diaphragm construction in accordance with Section 2308 of the IBC or Chapters 5 and 8 of the IRC. When TJI 110, TJI 210 or TJI 230 series I-joists are used in floor diaphragm construction, the thickness of the sheathing must be 19/32 inch (15.1 mm) or greater. 4.15 TJI Joists as Engineered Diaphragm Framing Members: TJI 110, TJI 210, TJI 230, TJI 360, TJI 560, TJI 560D, TJI s31, TJI s33, and TJI s47, joists may be used as framing members in blocked and unblocked engineered diaphragms designed using Table 2306.2.1(1) of the 2009 IBC, or Tables 4.2A and 4.2C of the ANSI/AWC Special Design Provisions for Wind and Seismic (SDPWS), subject to the limitations specified in Table 2 of this report. TJI L65, TJI L90, TJI H90, TJI HD90 and TJI HS90 joists may be used as framing members in diaphragms designed in accordance with the applicable code. The closest permitted sheathing nail spacing in a single row is 3 inches (76 mm) on center for 10d common nails or 2 inches (51 mm) on center for 8d common nails. 4.16 Cantilevered TJI Joists: TJI joists are permitted to be installed with cantilevered ends, provided the cantilevers have a maximum length equal to one-third of the adjacent span and support uniform loads only, unless designed by a design professional. 4.17 TJI Joists with Flak Jacket™ Protection Used in Fire Protected Floors: TJI® Joists with Flak Jacket™ protection applied to both sides of the web and vertical sides of the bottom flange are an alternative to the 2-by-10 dimension lumber, prescribed in the 2015 IRC Section R302.13 Exception 4 (2012 IRC Section R501.3 Exception 4), and have met the requirements of a floor assembly demonstrating equivalent floor performance. TJI® Joists with Flak Jacket™ protection are identified in the field by a Flak Jacket™ Protection stamp or label placed on the web of the I-joist member.

L = Clear span in feet W = Uniform load in pounds per lineal foot. EI = From table. K = From table. 3The stated reference design values are for loads of normal duration. Adjustments to the reference design values must be in accordance with the applicable code, with the exception noted in footnote 10 below. 4Interpolation between bearing lengths and joist depths is permitted for reference design reactions. 5The minimum bearing length is permitted to be reduced for joists supported by hangers if supplemental nail attachment is provided to the web stiffener. 6Required bearing lengths have been determined based on Weyerhaeuser TJI Joist products. Allowable bearing stresses on supporting members must be checked. 7Referenced design reactions require 51/4-inch and 7-inch bearing lengths at intermediate supports. 8Joist weights shown are calculated on a rational basis, are based on the heavier of eastern or western species products and are suitable for dead load calculation. Contact the producing plant for shipping weight information if needed. 9Applicable to TJI HD90 and TJI HS90 joists only. Tabulated values indicate reference design bearing reactions for a 21/2-inch bearing length at end supports. 13/4-inch end bearing lengths are also permitted; with reference design reactions of 1600 lbs. without web stiffeners for depths up to and including 18 inches; with web stiffeners the reference design reaction is 2255 lbs. for the 117/8 inch depth and 2450 lbs. for all other depths. 10The reference design moment values listed in Table 3 may not be increased by any code allowed repetitive-member use factor. 11Applicable to TJI HD90 and TJI HS90 joists only. Reference design reaction values are based on applicable hanger seat length (interpolated as per note 4 above) may be increased 510 lbs. when supported by Simpson Strong-Tie Co.

Charts are based on simple spans and uniform load applications or applicable building code provisions for concentrated loads (2000 lbs. over 2.5 square feet) with 25 psf dead load and 20 psf partition load. 2. For uniformly loaded multiple span applications holes must be located 1.0 inch farther from the support for each foot of joist span, than the values indicated in the Charts. 3. Holes are not allowed in cantilever areas unless specifically designed by a qualified design professional. 4. Where more than one hole is to be cut in the web, the clear distance between holes must be twice the length of the longest dimension of the largest adjacent hole. 5. Hole sizes shown are hole sizes, not duct sizes. 6. Rectangular hole sizes are based on measurement of the longest side. 7.
