2017 FBC/ASCE-7 DESIGN PRESSURE CALCULATIONS
Proiect Information:
Mean Height = 10' Exposure: C Basic/Ultimate Wind Speed: V,,I =170 mph
Length = 65' Category: II Nominal Wind Speed: V.d=V,,it*q0.6
Width = 45' Slope: 6/12 = 26.6° _ (asd = allowable strength design)
Parapet Wall: N/A Residential KZ = 0.85, Kzt =1.0, Kd = 0.85
Design Calculations:
Velocity Pressure: q = 0.00256*KZK,tKdV2
Velocity Pressure („ lt): q=0.00256(0.85)(1.0)(0.85)(170)2] = 53.45 psf
Velocity Pressure (mod): q=0.00256(0.85)(1.0)(0.85)(170*�0.6)2] = 32.07 psf
Width of Pressure Coefficient: 0.1(45')
0.4(10')
Effective Wind Area: <1 Oft
External Pressure Coefficient:
1)
GCP1
= -0.9
2)
GCP2
= -1.7
3)
GCP3
= -2.6
Design Pressures Based on Vasd: ,

= 4.0' } use: 4'0"
Internal Pressure Coefficient:
1) GCP; = 0.18
1) Field P1 = 32.07*[(-0.9) — (0.18)] = -34.6 psf
2) Perimeter P2 = 32.07* [(- 1.7) — (0.18)] = -60.3 psf
3) Corners P3 = 32.07* [(-2.6) — (0.18)] = -89.2 psf
