d. MEMBERS fabricated from plate or bar stock materials <br />shall have flanges and webs joined on one side of the web <br />by a submerged arc continuous weld process. <br />1.4.5 SECONDARY FRAMING <br />SECONDARY FRAMING shall be <br />distribute the loads to the pri.m <br />include the eave struts, purlins, <br />miscellaneous structural members. <br />cold-formed light gage sections, <br />structural sections, <br />the structural members which <br />ary framing systems, and shall <br />girts, wind bracing and other <br />They shall be manufactured of <br />welded plate sections and/or <br />1. EAVE STRUTS shall be nominal 8" or 10" deep "cee" shaped <br />members, and shall be manufactured of 14 or 12 gage steel. and <br />shall be designed as simple span for the specified loads. <br />2. PURLINS and GIRTS shall be nominal 811, 10" or 12" deep "zee" <br />shaped or "cee" shaped members, and shall be manufactured of 16, <br />15, 14 or 12 gage steel designed as simple span, partially <br />continuous or continuous for the specified loads. <br />3. WIND BRACING shall be a system of diagonal cable bracing, <br />portal, fixed base or diaphragm bracing designed for the specified <br />loads in accordance with design practices. They shall normally <br />utilize rods, cables, diaphragm action, angles and/or welded plate <br />or structural members. <br />4. MISCELLANEOUS STRUCTURES shall normally be those members to <br />augment the pri.mary, primary endwall and secondary framing systems. <br />They shall include members such as: base angles, flange braces, <br />jambs, headers, and bridging or sag members, and shall be designed <br />to be supportive of the framing systems. <br />5. MATERIALS used in the fabrication of secondary framing systems <br />shall be designed utilizing standard practices, generally in <br />compliance with the applicable sections of A.I.S.C. and A.I.S.I. <br />a. COLD FORM MEMBERS shall be fabricated of material <br />conforming to the physical requirements of ASTM A570 and <br />shall have a minimum yield strength of 55,000 psi. <br />b. CABLE BRACING shall be fabricated of material <br />conforming to the physical requirements of ASTM A475-78 <br />for extra high strength grade. <br />c. ROD BRACING shall be fabricated of material <br />conforming to the physical requirements of ASTM A36 and <br />shall have a minimum yield strength of 36,000 psi. <br />d. OTHER YIELD STRENGTH MATERIALS shall be used based on <br />the particular building design requirements. <br />72. <br />
