§ 129-96. Design and construction.

(a)

Generally. Signs and sign structures shall be designed and constructed to resist wind and seismic forces. All bracing systems shall be designed and constructed to transfer lateral forces to the foundations. For signs on buildings the dead and lateral loads shall be transmitted through the structural frame of the building to the ground in such a manner as not to overstress any of the elements thereof.

(b)

Wind loads. Signs and sign structures shall be designed and constructed to resist wind forces as specified in the Uniform Building Code.

(c)

Seismic loads. Signs and sign structures shall be designed and constructed to resist seismic forces as specified in the Uniform Building Code.

(d)

Combined loads.

(1)

Wind and seismic loads need not be combined in the design of signs or sign structures; only that loading producing the larger stresses need be used.

(2)

Vertical design loads, except roof live loads, shall be assumed to be acting simultaneously with the wind or seismic loads.

(e)

Allowable stresses. The design of wood, concrete, steel or aluminum members shall conform to the requirements of the Uniform Building Code. Loads, both vertical and horizontal, exerted on the soil shall not produce stresses exceeding those specified in the Uniform Building Code.
