1339.06 ERECTION REQUIREMENTS FOR ALL SIGNS.

   Loads, allowable stresses and materials for all signs shall be as follows:

   (a)   Pressure. For the purposes of determining wind pressure all signs shall be designed and constructed to withstand wind pressures specified in Section 1112.0 of the Ohio Basic Building Code as may be amended from time to time.

   (b)   Projected Exposed Area. The exposed area subjected to wind pressure shall be the total area of all parts of the sign including structural framing on a plane perpendicular to the direction of the wind. In determining the stress in any member the wind shall be assumed to flow from the horizontal direction, and from that inclination from the vertical (but not to exceed twenty degrees above or below the horizontal) which produces the maximum stress in that member.

   (c)   Allowable Stresses and Materials. In all signs the allowable stresses, materials and details of design shall render all signs safe to person, property and the movement of traffic along all streets and public thoroughfares. All signs shall be designed, constructed and installed in conformity with the provisions of this chapter and applicable statutes of the State. All signs shall be supported by sign structures which are made of wood, concrete or steel, designed and constructed to resist wind pressures and dead and lateral loads in accordance with the following specifications:

      (1)   For steel sign structures. American National Standards Institute, Inc. Building Code requirements for structural steel. Secondary members in contact with or directly supporting the facing may, in all types of signs, be formed of light gauge steel, provided such members are designed in accordance with the Light Gauge Steel Design Manual of the American Iron and Steel Institute.

      (2)   For wood. National Design specifications for Stress Grade Lumber and its fastenings, recommended by the National Lumber Manufacturers Association.

      (3)   The working stress of chains, wire, ropes and steel guy rods and their fastenings shall not exceed one-quarter of their ultimate strength.
