ASCE 7-10 DESIGN PRESSURE CALCULATIONS
In Accordance with Chapter 30, Part I
Proiect Information:
Height = 10'
Length = 200'
Width = 107'
Parapet Wall: < 3'
Design Calculations:
Flat Wood Deck
Exposure: C
Category: II
Slope: < 7*
Ultimate Windspeed: Vli= 170 mph
Basic Windspeed: V�d = 132 mph
Kz = 0.85
Velocity Pressure: q = 0.00256*[(0.85)(1.0)(1.0)(132f]
= 37.9 psf
Width of Pressure Coefficient: 0.1(107') = 10.7'
0.4(10') = 4.0' } use: 4T
Effective Wind Tributary Area: <10fl?
For parapet height 3 feet or larger, zone three (3) can be treated as zone two (2) (ASCE 7-10).
External Pressure Coefficient:
1) GCPl = -1.0
2) GCP2 = -1.8
3) GCP3 = -2.8
Design Pressures:
Zone 1 Field:
Zone 2 Perimeter:
Zone 3 Comers:
Internal Pressure Coefficient:
1) GCPi = 0.18
PI = 37.9*(-1.0 - 0.18) = 44.7 psf
P2 = 37.9*(-1.8 - 0.18) = -75.1 psf
P3 = 37.9*(-2.8 - 0.18) = -113.0 psf
