Input:
ASCE 7-10 Strength Design Load & Alipwable Stress Design
Wind Speed =140 mph
Building Exposure = C (Open Terrain with Scattered Obstructions)
Internal Pressure Coefficient GCpi = 0.18 Enclosed Building
Roof angle is less than or equal to 10° or flat (External Pressure Coefficient is reduced 10%)
Kzt = 1.00
Kd = 0.85
Mean Roof Height = 20 ft
Output:
Velocity Pressure Exposure Coefficient "Kz max." = 0.9
Per Table 30.3-1, page 317
LRFD uses wind speed Vult =140 mph
Velocity Pressure (qh LRFD) = 38.38 psf = .00256*Kz*Kzt*Kd*V^2 lb/ft^2
Per eq.30.3-1, page 316
.ASD uses wind speed Vasdl =108 mph
Velocity Pressure (qh ASD) = 23.03 psf = .00256*Kz*Kzt*Kd*V^2*0.6 lbJft^2
Least Width = 50 ft a = 5 ft (Zone 5)
10% of least width or 0.4h, whichever is smaller but not less than 3 ft.
