Wind Load Calculation As Per Asce 7-05

This is the pressure acting on the outside surfaces.

C&C includes roof panels, wall studs, windows, and curtain walls. Pressures are higher and more localized.

p = qh × G × Cp – qi × G × Cpi (Equation 6-20) wind load calculation as per asce 7-05

But here Cp is from Figure 6-11 through 6-17 (based on Effective Wind Area).

Key difference: Effective wind area = span × (span/3) but not less than span × width tributary. Smaller areas = higher Cp. This is the pressure acting on the outside surfaces

Example for roof zone (low-slope, Exposure C, qh = 30 psf):

Thus C&C pressures are often the governing load for cladding design. C&C includes roof panels, wall studs, windows, and
