FBC 2014/ASCE 7-10 DESIGN PRESSURE CALCULATIONS
Proiect Information:
Height= 16' Exposure: C
Length = 104' Category: II
Width = 65' Slope: < 7°
Parapet Wall: 18" to 24" Commercial
Design Calculations:
Basic/Ultimate Wind Speed: V ii=170 mph
Nominal Wind Speed: Vasd=V dt*y0.6
(asd = allowable strength design)
K� = 0.86, Kzt = 1.0, Kd = 0.85
Velocity Pressure: q = 0.00256*KzK,&V2
Velocity Pressure ("it): q=0.00256(0.86)(1.0)(0.85)(170)2] = 54.08 psf
Velocity Pressure (asd): q=0.00256(0.86)(1.0)(0.85)(170*v0.6)2] = 32.45 psf
Width of Pressure Coefficient: 0.1(65) = 6.5'
0.4(16') = 6.4' ) use: 6'6"
Effective Wind Area: <10ft2
For parapet height three feet (3D or larger, zone three (3) shall be treated as zone two (2).
