PROJECT: Theodore Ocem Residence 26 Gauge GulfRib Panel
ADDRESS: 2803 Cortez Blvd. Fort Pierce,Florida 34981
FBC 2014/ASCE 7-10 DESIGN PRESSURE CALCULATIONS
Proiect Information:
Mean Height=Max. 15' Exposure: C Basic/Ultimate Wind Speed: Vi1t=170 mph
Length= 68' Category: H Nominal Wind Speed: Vasd=Vi1t*40.6
Width= 46' Slope: 5/12 =22.6° (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*KZKzYKdV2
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*40.6)2] =32.07 psf
Width of Pressure Coefficient: 0.1(46') = 4.6'
0.4(15') = 6.0' ) use: 5'0"
Effective Wind Area: <1 W
External Pressure Coefficient: Internal Pressure Coefficient:
1) GCP1 = -0.9 1) GCPi = 0.18
2) GCP2 = -1.7
3) GCP3 = -2.6
Design Pressures Based on Vasd:
1) Field PI = 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
