Assume: V = 100 mph, Kz = 0.7, Kzt = 1.0, Kd = 0.85, G = 0.85, Cp = -0.9 (suction), GCpi = +0.18.
Consult the ASCE 7-05 wind maps. Unlike newer versions that use "Ultimate" speeds, ASCE 7-05 uses (3-second gusts). Typical values range from 85 mph in the interior U.S. to 150+ mph in hurricane-prone coastal regions. Step B: Find the Velocity Pressure ( wind load calculation as per asce 7-05
