Properties evaluated: ■ Structural ■ Sound ratings ■ Fire -resistance ratings ■ Floor Fire Protection 2.0 USES TJI joists are prefabricated wood 1-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 R502.1.2 of the IRC (R502.1.4 for the 2012 IRC). 3.0 DESCRIPTION 3.1 General: TJI joists are prefabricated wood I -joists having 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 A Subsidiary of the International Code Council° 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. 3.2 Material Specifications: 3.2.1 Flanges: Flange material is Microllam° laminated veneer lumber (LVL) described 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. Web material thickness requirements are noted in Table 1 of this report. 3.2.3 Adhesives: Adhesives are of the types specified in the quality control manual that contains Weyerhaeuser manufacturing standards. 4.0 DESIGN AND INSTALLATION 4.1 General: The design and installation of TJI joists described in this report must comply with Sections 4.2 through 4.16. Additionally, design of TJI joists is governed by the applicable code and corresponding editions of ANSI/AWC National Design Specification' for Wood Construction (NDS). 4.2 Design Values: Table 3 specifies reference design moments, reactions, vertical shear forces, and joist stiffness (0). Reference design reactions are based on minimum bearing lengths of 11/4 inches and 31/2 inches (45, 64 and 89 mm), for simple spans; and 3'/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:5 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).

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 flange glue lines, must be determined in accordance with ESR-1387 and the applicable code. Allowable nail spacings for TJI joist diaphragm applications must be as specified in Sections 4.14 and 4.15, and Table 2. For non -diaphragm applications, the spacing of fasteners installed into the face grain of Microllam LVL 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 flanges must be greater than or equal to the closest permitted on -center spacing requirements detailed in ESR-1387. 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 5 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 Figure 2 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 Figure 2 are permitted to be used in the fire -resistive -rated Assemblies B, C, D, E, F, and G described in Figures 3B through 3G. 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 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 and TJI 560D joists may be used as framing members in blocked and unblocked engineered diaphragms designed using 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. 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 Dupont Durable Fire Resistant (FR) laminate applied to both sides of the web are an alternative to 2x10 dimension lumber, prescribed in the 2018 and 2015 IRC Section R302.13 Exception 4 and 2012 IRC Section R501.3 Exception 4.
