ESR-2762 | Most Widely Accepted and Trusted Page 2 of 8 <br /> <br />minimum No. 18 gage [0.0466 inch (1.184 mm) total <br />thickness] steel complying with ASTM A653 HSLAS <br />Grade 60 with a minimum G90 galvanized coating <br />[0.00076 inch (0.019 mm) on each side] and having a <br />base-metal thickness of 0.0456 inch (1.158 mm). Each <br />tooth is 0.375 inch (9.5 mm) long. The teeth are punched <br />in pairs and formed at right angles to the face of the <br />parent metal so that two teeth per hole occur along the <br />length. The spacing along the longitudinal direction of <br />each punched slot is 1 inch (25.4 mm) on center. <br />3.4.1 AS 18S6: Each plate has six teeth per square <br />inch. The punched slots are spaced a minimum of <br />0.25 inch apart and are grouped in sets of three and four <br />as shown in Figure 3. <br />3.4.2 AS 18S5: Each plate has five teeth per square <br />inch. The punched slots are spaced a minimum of <br />0.25 inch apart and are grouped in sets of two and three <br />as shown in Figure 4. <br />3.5 ASHP: <br />Simpson Strong-Tie ASHP Hinge Plate Connectors are <br />manufactured from minimum No. 18 gage [0.0460 inch <br />(1.168 mm) total thickness] steel complying with ASTM <br />A653, SS Grade 40 with a minimum G90 galvanized <br />coating [0.00076 inch (0.019 mm) on each side] and <br />having a minimum base-metal thickness of 0.0445 inch <br />(1.130 mm). The Hinge Plate Connector consists of two <br />23/8” x 53/8” (60 mm by 137 mm) plates overlapping by <br />approximately 23/8” (60 mm). Each plate of the connector <br />is comprised of approximately 2.0” x 3.0” (51 mm x <br />76 mm) area of teeth that are 0.375 inch (9.5 mm) long. <br />The teeth are punched in pairs and formed at right <br />angles to the face of the parent metal so that two teeth <br />per hole occur along the length. The spacing along the <br />longitudinal direction of each punched slot is <br />approximately 1 inch (25.4 mm) on center, and the pairs <br />are spaced 0.25 inch (6.35 mm) on center along the <br />length of the plate. Alternating rows of teeth are <br />staggered 0.125 inch (3.18 mm) from adjacent rows. <br />See Figure 6. <br />4.0 DESIGN AND INSTALLATION <br />4.1 General: <br />The design, manufacture and installation of wood <br />trusses employing the metal connector plates and hinge <br />plate connectors must comply with IBC Section 2303.4 <br />and IRC Section R502.11 or R802.10, as applicable. All <br />truss plates are pressed into the wood for the full depth <br />of their teeth by hydraulic-platen embedment presses, <br />multiple roller presses that use partial embedment <br />followed by full-embedment rollers, or combinations of <br />partial embedment roller presses and hydraulic-platen <br />embedment presses that feed trusses into a stationary <br />finish roller press. Trusses must be assembled within the <br />tolerances provided by the Truss Plate Institute (TPI) <br />Quality Criteria for the Manufacture of Metal Plate <br />Connected Wood Trusses, shown as Chapter 3 in <br />ANSI/TPI 1, National Design Standard for Metal Plate <br />Connected Wood Truss Construction. <br />4.2 ASHP Hinge Plate Connectors must be installed in <br />pairs in the 180-degree position on opposite faces of <br />truss chord members, which must be composed of sawn <br />wood lumber with a minimum specific gravity of 0.42. <br />The maximum allowable gap between the ends of the <br />connected wood members at the ASHP hinge plate <br />connector must be 1 inch (25.4 mm). <br />4.3 Design Values: <br />4.3.1 AS20, AS 20HS, AS 18, AS 18S, AS 18S6 and <br />AS 18S5: Allowable design values for Simpson Strong- <br />Tie AS 20, AS 20HS, AS 18, AS 18S, AS 18S6 and <br />AS 18S5 metal connector plates to be used in the design <br />of metal-plate-connected wood roof and floor trusses are <br />shown in Tables 1 and 2 of this report. Allowable design <br />values are applicable when the connection is made with <br />identical plates on opposite sides of the joint. <br />4.3.2 ASHP: Allowable design values for Simpson <br />Strong-Tie metal ASHP Hinge Plate Connectors are <br />shown in Table 3. Imposed forces at the joint and <br />internal stresses within the truss containing the joint <br />must be determined using a structural model with a pin <br />at the hinge joint location. The design load of the ASHP <br />connector, due to combined shear and axial loads, must <br />not exceed the Hankinson formula as follows: <br />Fѳ ≤ Pѳ <br />where, <br />ѳ = (Fa v <br />. <br />ѳ = (Pa v a x (sin Ѳ)v x (cos Ѳ) <br />. <br />a <br />v <br />a <br /> <br />v <br />Ѳ ѳ and the length of the plate <br />5.0 CONDITIONS OF USE <br />The Simpson Strong-Tie metal connector plates and <br />hinge plate connectors for wood trusses described in this <br />report comply with, or are suitable alternatives to what is <br />specified in, those codes listed in Section 1.0 of this <br />report, subject to the following conditions: <br />5.1 This evaluation report and the manufacturer’s <br />published installation instructions, when required by <br />the code official, must be submitted at the time of <br />permit application. <br />5.2 Installation must comply with this report, the <br />manufacturer’s published installation instructions, <br />and the applicable code. In the event of a conflict <br />between the manufacturer’s published installation <br />instructions and this report, this report governs. <br />5.3 Each application for a building permit, where these <br />metal connector plates and hinge plate connectors <br />are to be used, must be accompanied by <br />calculations, details and other documentation <br />showing that the design, manufacture and <br />proposed installation conforms with the <br />requirements of the applicable code. Design and <br />calculations must be prepared and sealed by a <br />registered design professional where required by <br />the statutes of the jurisdiction in which the project is <br />to be constructed. <br />5.4 This report establishes allowable design values <br />only. For items not covered by this report, such as <br />truss design, fabrication, quality assurance and <br />inspection, refer to ANSI/TPI 1, engineering <br />drawings and the applicable code. <br />5.5 The applied design values used in the design of <br />trusses using Simpson Strong-Tie metal connector <br />plates, must not exceed the allowable lateral <br />resistance, tension and shear values listed in <br />Tables 1 and 2 of this report.
