In order to utilize wind loads from this part, the building shall meet the following requirements:
Ps represents the net pressures (sum of internal and external) to be applied to the horizontal and vertical projections of building surfaces. For the horizontal pressures, Ps is the combination of the windward and leeward net pressures. Ps may be determined from the following equation:
Ps = Kzt (Vult2/1152)Palt
where:
Kzt = Topographic factor as defined in Chapter 26 of ASCE 7.
Palt = Alternative simplified design wind pressure from Table Palt.

Exp C | 30 psf | |
Exp D | 35 psf |
Overhang Vertical Pressurec | ||
Exp B | -40 psf | |
Exp C | -48 psf | |
Exp D | -56 psf |
aValues are for ultimate wind design (Vult). Multiply by 0.6 for allowable stress design (ASD).
bFor vertical pressure, the above values are negative (upward).
cNegative values are upward.
