Wind Load Calculation As Per Asce 7-05 [repack] -

Thus C&C pressures are often the governing load for cladding design.

: Topographic Factor (used for buildings on hills or escarpments). cap K sub d wind load calculation as per asce 7-05

If the building is not on an isolated hill, ridge, or escarpment, ( K_zt = 1.0 ). If it is, use with parameters ( K_1, K_2, K_3 ) from Figure 6-4. This factor rarely exceeds 1.3 for extreme topography. Thus C&C pressures are often the governing load

Where:

The standard formula for calculating velocity pressure in ASCE 7-05 is use with parameters ( K_1

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