2017 FBC/ASCE-7 DESIGN PRESSURE CALCULATIONS
Proiect Information:
Mean Height < 15' Exposure: D Basic/Ultimate Wind Speed: V,,tt=170 mph
Length = 39' Category: R Nominal Wind Speed: V.d=Vwt*40.6
Width = 22' Slope: 3/12 =14' (asd = allowable strength design)
Parapet Wall: N/A Residential KZ =1.03, Kzt =1.0, Kd = 0.85
Design Calculations:
Velocity Pressure: q = 0.00256*K7KztKdV2
Velocity Pressure (,,It): q=0.00256(1.03)(1.0)(0.85)(170)2] = 64.77 psf
Velocity Pressure (.d): q=0.00256(1.03)(1.0)(0.85)(170*40.6)2] = 38.86 psf
Width of Pressure Coefficient: 0.1(22')
0.4(15')
Effective Wind Area: <1 Of 2
External Pressure Coefficient:
1)
GCP 1 =
-0.9
2)
GCP2 =
-1.7
3)
GCP3 =
-2.6
Design Pressures Based on Vasa:
= 2.2'
= 6.0' } use: 3'0"
Internal Pressure Coefficient:
1) GCP; = 0.18
1) Field
P1 = 38.86*[(-0.9)
— (0.18)]
= -42.0 psf
2) Perimeter
P2 = 38.86*[(-1.7)
— (0.18)]
= -73.1 psf
3) Corners
P3 = 38.86* [(-2.6)
— (0.18)]
= -108.0 psf
