Signs and sign structures shall be designed and constructed to resist wind forces as specified in Chapter 2 of the National Structural Code for Buildings (NSCB). 5.3 Seismic Loads. Signs and sign structures shall be designed and constructed to resist seismic forces as specified in Chapter 2 of the NSCB. 5.4 Combined Loads. Wind and seismic loads need not be combined in the design of signs or sign structure, only that loading producing the larger stresses need be used. Vertical design loads, except roof live loads, shall be assumed to be acting simultaneously with the wind or seismic loads. 5.5 Allowable Stresses. The design of wood, concrete, or steel members shall conform to the requirements of Chapter 3, 4 and 5, of the NSCB. Loads, both vertical and horizontal, exerted on the soil shall not produce stresses exceeding those specified in Chapter 7 of the NSCB. The working stresses of wire rope and its fastenings shall not exceed 25 percent of the ultimate strength of the rope or fastener. Working stresses for wind or seismic loads combined with dead loads may be increased as specified in Chapter 2 of the NSCB. 6. Construction: 6.1 General. The supports of all signs or sign structures shall be placed in or upon private property and shall be securely built, constructed, and erected in conformance with the requirements of this Rule. 6.2 Materials. Materials of construction for signs and sign structures shall be of the quality and grade as specified for buildings in this Rule. In all signs and sign structures, the materials and details of construction shall, in the absence of specified requirements, conform with the following: 6.2.1 Structural steel shall be of such quality as to conform with ASTM A 36. Secondary members in contact with or directly supporting the display surface may be formed of light gauge steel, provided such members are designed in accordance with the specifications of the design of light gauge steel as specified in ASTM A 242 and, in addition, shall be galvanized. Secondary members, when formed integrally with the display surface, shall be not less than No. 24 gauge in thickness. When not formed integrally with the display surface, the minimum thickness of the secondary members shall be No. 12 gauge. The minimum thickness of hot-rolled steel members furnishing structural support for signs shall be 6.35 mm. except that if galvanized, such members shall be not less than 3.18 mm. thick. Steel pipes shall be of such quality as to conform with ASTM A 36. Steel members may be connected with one galvanized bolt provided that connection is adequate to transfer the stresses in the members. 6.2.2 Anchors and supports, when of wood and embedded in the soil, or within 150 mm. of the soil, shall all be of heartwood of a durable species or shall be pressuretreated with an approved preservative. 7. Anchorage: 7.1 Members supporting unbraced s...
