Property evaluated: Structural 2.0 USES The OJ Series prefabricated open web wood joists are used as uniformly loaded floor joists and roof joists in simple span and cantilever applications. 3.0 DESCRIPTION 3.1 General: The OJ series prefabricated open web wood joists have solid-sawn lumber flanges connected by solid-sawn lumber vertical and diagonal web members forming a diagonal webbed truss along the length; except at one end, which has a continuous oriented strand board (OSB) web to permit trimming to length in the field. The top and bottom flanges are parallel, creating a constant depth joist. The vertical- and diagonal-to-flange connection is a proprietary glued finger joint, and the OSB end section connection is a proprietary glued tongue-and-groove joint to the flanges and to a vertical web transition post. Joist depths vary from 9.5 inches to 16 inches (241 mm to 406 mm). The joist has a top and bottom, with the bottom flange marked for proper orientation during joist placement. A vertical web member is always placed at the joist end opposite the OSB web end. See Table 1 and Figure 1 for descriptive information. 3.2 Material: 3.2.1 Flanges: The OJ series flange material is solid- sawn, spruce-pine-fir (SPF) finger-jointed lumber meeting the grade requirements listed in the approved quality control manual. Flange width, thickness and grade are specified in Table 1. 3.2.2 Diagonal Webs: The OJ series diagonal web material is SPF proprietary grade solid-sawn lumber meeting the requirements listed in the approved quality control manual. Diagonal web size and grade are specified in Table 1. 3.2.3 Vertical Webs: The OJ series end post and web post material is SPF proprietary grade solid-sawn lumber meeting the size and grade requirements listed in the approved quality control manual. 3.2.4 OSB Webs: The OJ series OSB web material is nominally 3/8-inch thick complying with DOC Voluntary Product Standard PS2, Exposure 1 and requirements listed in the approved quality control manual. The OSB web is continuous from the web post to the ends of the flanges. The OSB is oriented with face grain parallel to the joist flanges. 3.2.5 Adhesive: The adhesive used in the OJ series joist fabrication complies with ASTM D2559, Section 5.3.3 of ASTM D5055-08a and requirements listed in the approved quality control manual. 4.0 DESIGN AND INSTALLATION 4.1 General: The design and installation of the OJ series prefabricated open web wood joists described in this report must comply with Sections 4.2 through 4.12 and the manufacturer’s published installation instructions. Additionally, design of the OJ series joists is governed by the applicable code and corresponding editions of the ANSI/AF&PA National Design Specification for Wood Construction (NDS). 4.2 Allowable Capacity: Table 2 specifies allowable moment, shear, joist bending stiffness (EI) and shear deflection coefficient (K). Reference design values given in Table 2 must be ESR-2999 | Most Widely Accepted and Trusted Page 2 of 5 adjusted by applicable factors in accordance with Sections 4.2.1 through 4.2.5. 4.2.1 Load Duration Factor, CD: Adjustments for duration of load apply to the reference design values in accordance with Section 7.3.2 of the NDS. 4.2.2 Wet Service Factor, CM: OJ series joists must be installed in dry, covered conditions where the in-service moisture content of the joist is less than 16 percent. The wet service factor, CM, for OJ series joists under these conditions is 1.0. 4.2.3 Temperature Factor, Ct: Where OJ series joists will be exposed to sustained in-service temperatures greater than 100°F (38°C), the reference design values must be adjusted by the temperature factor, Ct, in accordance with Section 7.3.4 of the NDS. 4.2.4 Beam Stability Factor, CL: The OJ series joist compression flange must be provided with lateral support in accordance with Section 4.7. The beam stability factor, CL, for OJ series joists under these conditions is 1.0. 4.2.5 Repetitive Member Factor, Cr: The applicable repetitive member factor, Cr, for reference design moments is 1.0. 4.3 Fasteners: Reference fastener withdrawal and lateral design values for nails installed into the flanges must be determined in accordance with the NDS and the applicable code, using a maximum specific gravity of 0.42. Fastener spacing must comply with the requirements prescribed by the applicable code for nails installed in sawn lumber. 4.4 Member Cutting: Flanges, diagonal webs and vertical webs must not be cut or notched. Table 4 shows the size of duct that will pass through the open web portions of the OJ series joist. No hole cutting is permitted in the OSB web portion of the joist. 4.5 Web Stiffeners on OSB End: Field-installed web stiffeners must be provided at bearings when required by Table 3. Web stiffeners must be sized and installed as described in Figure 2. 4.6 Bearing Length: Ends of OJ series joists must be provided a minimum of 11/2 inches (38.1 mm) of bearing length. Allowable end reactions based on bearing lengths are presented in Table 3. Linear interpolation between values presented is permitted. 4.7 Lateral Support: The OJ series joist compression flange requires continuous lateral support and joist ends require restraint to prevent rollover and resist rotation. Methods specified in the applicable code for lateral support of sawn lumber are acceptable. Bridging is not required for floor joist applications. 4.8 Joist Span: OJ series joist span must be determined in accordance with Section 3.2.1 of the NDS. Vertical shear calculations must include all loads within the span from face to face of supports. 4.9 Cantilevers: The OJ series joist OSB end section may be cantilevered beyond the support a maximum of 24 inches (610 mm), or one-third of the adjacent span, whichever is less. The interior support adjacent to the cantilever must have a bearing length of 31/2 inches (89 mm) located entirely within the OSB web section of the joist. 4.10 Simple Span Deflection: Mid-span deflection for a uniformly loaded simple span OJ series joist must be calculated using the equation given in the footnotes to Table 2. 4.11 Concentrated Loads: Design for concentrated loads is beyond the scope of this report. 4.12 End Blocking Panels: Where OJ series joists have bearing walls above aligned over joists end bearings, either full-depth blocking between joists or rim board is required to support the wall above. 5.0 CONDITIONS OF USE The OJ series prefabricated open web wood joists described in this report comply with, or are suitable alternatives to what is specified in, those codes listed in Section 1.0 of this report, subject to the following conditions: 5.1 OJ series joists must be installed in accordance with this report, the manufacturer’s published installation instructions and the approved plans. If there are conflicts between this report and the manufacturer’s published installation instructions or plans submitted for approval, this report governs. 5.2 Design calculations and details for specific applications must be furnished to the code official. Calculations and drawings must be prepared, signed and sealed by a registered design professional where required by the statutes of the jurisdiction in which the project is to be constructed. 5.3 Use of the OJ series joists is limited to dry, interior applications in accordance with Section 4.2.2. 5.4 The OJ series joists are manufactured by Distribution Open Joist 2000 Inc. at their plant located in Trois- Rivieres, Quebec, Canada under a quality-control program with inspections by ICC-ES. 6.0 EVIDENCE SUBMITTED Data in accordance with the ICC-ES Acceptance Criteria for Prefabricated Parallel Chord Wood Trusses (AC224) dated October 2015. 7.0 IDENTIFICATION OJ series prefabricated open web wood joists are identified by a stamp that includes the product designation, the evaluation report number (ESR-2999), the manufacturer’s name or logo, the manufacturing plant location, and the production date.
