Figure 1. Examples of two trusses constructed of structural steel tubing with 36,000 psi minimum yield stress, based on 6-ft spacing between frames. The upper truss is designed to withstand 95 mph wind loads and the lower truss is designed to withstand 105 mph wind loads. Higher winds are mre prevalent in coastal areas and in south Florida. Designs are based on the AISC Manual of Steel Construction, 8th Edition, American Institute of Steel Construction, Chicago, Illinois, 1980.
