CLIENT: All Area Roofing
ADDRESS: 3921 S. US Highway 1 Fort Pierce,Florida 34982
PROJECT: Lawrence Residence 5-V Crimp Roof Panel
ADDRESS: 743 SW Tatum Terrace Port Saint Lucie,Florida
FBC 2014/ASCE 7-10 DESIGN PRESSURE CALCULATIONS
Project Information:
Mean Height= 8' Exposure: C Basic/Ultimate Wind Speed: VUIt=170 mph
Length= 56' Category: H Nominal Wind Speed: Vasd=Vi1t*40.6
Width= 46' Slope: 3/12= 14° (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)(170)2] = 53.45 psf
Velocity Pressure (asd): q=0.00256(0.85)(1.0)(0.85)(170* 0.6)2] =32.07 psf
Width of Pressure Coefficient: 0.1(46') = 4.6'
0.4(8') = 3.2' ) use: 3'6"
Effective Wind Area: <10ft2
External Pressure Coefficient: Internal Pressure Coefficient:
1) GCP 1 = -0.9 1) GCPi = 0.18
2) GCP2 = -1.7
3) GCP3 = -2.6
Design Pressures Based on Vasd:
1) Field P1 = 42.64*[(-0.9)—(0.18)] =-46.0 psf
2) Perimeter P2 = 42.64*[(-1.7)—(0.18)] =-80.2 psf
3) Corners P3 = 42.64*[(-2.6)—(0.18)] =-118.5 psf
