Sec. 98-59. Construction requirements generally.

(a) Compliance. The supports for all signs or sign structures shall be securely built, constructed and erected in conformance with the requirements of this Code.

(b) Materials. Materials used for the construction of signs and sign structures shall be of the quality and grade as specified for buildings in the 2000 International Building Code. In all signs and sign structures, the materials and details of construction shall, in the absence of specified requirements, conform with the following: Structural steel shall be of such quality as to conform with Chapter 16, 2000 International Building Code. 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 Chapter 16. Secondary members, when formed integrally with the display surface, shall not be less than number 18-gauge in thickness. When not formed integrally with the display surface, the minimum thickness of the secondary members shall be at least number 20-gauge in thickness. The minimum thickness of hot-rolled steel members furnishing structural support for signs shall be at least one-eighth inch. Steel members may be connected with one bolt provided the connection is adequate to transfer the stresses in the members.

(c) Nonstructural trim. Nonstructural trim may be of wood, metal, approved plastics or any combination thereof.

(d) Anchorage.

(1) Members supporting unbraced signs shall be so proportioned that the bearing loads imposed on the soil in either direction, horizontal or vertical, shall not exceed the safe values. Braced ground signs shall be anchored to resist the specified wind load acting in any direction. Anchors and supports shall be designed for safe-bearing loads on the soil. Anchors and supports shall penetrate to a depth belowground greater than that of the frostline.

(2) Signs attached to masonry, concrete or steel shall be safely and securely fastened thereto by means of metal anchors, bolts or approved expansion screws of sufficient size and anchorage to support safely the loads applied.

(3) No wooden block or plugs or anchors with wood used in connection with screws or nails shall be considered proper anchorage except in the case of signs attached to wood framing.

(e) Restrictions and combustible materials.

(1) All electric signs and electrical sign structures shall have structural members of incombustible materials.

(2) Ground signs may be constructed of any material meeting the requirements of this chapter, except as provided above.

(3) Wall signs, projecting signs, and signs on marquees shall be constructed of incombustible materials, except as provided in this section. No combustible materials other than approved plastics shall be used in the construction of electric signs.
