DATE: 10/23/18 JOB ORDER#: 18-4689
CLIENT: All Area Roofing
ADDRESS: 3921 S. US Highway 1 Fort Pierce,Florida 34982
PROJECT: Tammy Ogden Residence Integrity Metals 5V Crimp Roof Panel
ADDRESS: 204 Smallwood Avenue Fort Pierce,Florida
2017 FBC/ASCE-7 DESIGN PRESSURE CALCULATIONS
Project Information:
Mean Height=Max. 15' Exposure: C Basic/Ultimate Wind Speed: Vuit=165 mph
Length= 72' Category: II Nominal Wind Speed: V.d=Vuit*q0.6
Width= 36' Slope: 6/12=26.5° (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*KZKztKdV2
Velocity Pressure (,,It): q=0.00256(0.85)(1.0)(0.85)(165)2] =50.36 psf
Velocity Pressure (aid): q=0.00256(0.85)(1.0)(0.85)(165* 0.6)2] =30.21 psf
Width of Pressure Coefficient: 0.1(36') = 3.6'
0.4(15') = 6.0' } use: 4'0"
Effective Wind Area: <1 W
External Pressure Coefficient: Internal Pressure Coefficient:
1) GCP 1 = -0.9 1) GCP; = 0.18
2) GCP2 = -1.7
3) GCP3 = -2.6
Design Pressures Based on Vasd:
1) Field P1 = 3 0.21*[(-0.9)—(0.18)] =-32.6 psf
2) Perimeter P2 = 30.21*[(-1.7)—(0.18)] =-56.8 psf
3) Corners P3 = 30.21*[(-2.6)—(0.18)] =-84.0 psf
