2017 FBC/ASCE-7 DESIGN PRESSURE CALCULATIONS
Project Information:
Mean Roof Height = 10'
Length = 87'
Width = 73'
Parapet Wall: N/A
Design Calculations:
Exposure: C Basic/Ultimate Wind Speed: V„1t=170 mph
Category: II Nominal Wind Speed: V.d=V,it*40.6
Slope: 5/12 (asd = allowable strength design)
Residential KZ = 0.85, Kzt =1.0, Kd = 0.85
Velocity Pressure: q = 0.00256*K,-KztKdV2
Velocity Pressure (,,It): q=0.00256(0.85)(1.0)(0.85)(170)2] = 53.45 psf
Velocity Pressure (.d): q=0.00256(0.85)(1.0)(0.85)(170*40.6)2] = 32.07 psf
Width of Pressure Coefficient: 0.1(73) = 7.3'
0.4(10') = 4.0' } use: 4'0"
Effective Wind Area: <10ft2
For hip roofs with a roof slope of 25 degrees or less, zone three (3) shall be treated as
zone two (2).
External Pressure Coefficient:
1) GCP1 = -0.9
2) GCP2 = -1.7
3) GCP3 = -2.6
Internal Pressure Coefficient:
1) GCPi = 0.18

Attachment resistance expressed as a moment: Mf= 51 ft-lbf Polyset AH-160 Foam Set
(Table 4, Single Medium Paddy 30g)
1) Field :
Mri =
(34.6*0.289)
= 7.52 ft. lb =
2.5 ft. lb. < 51 ft. lb = PASS
2) Perimeter :
Mr2 =
(60.3*0.289)
— 7.52 ft. lb =
9.9 ft. lb. < 51 ft. lb = PASS
3) Corners :
Mr3 =
(89.2*0.289)
— 7.52 ft. lb =18.3
ft. lb. < 51 ft. lb = PASS
System is acceptable as approved with single medium paddy (30g) placement of the
Polyset AH-160 Foam Ahesive by ICP Ahdesives and Sealants based on the requirements
of Florida Product Approval # FL7804-R10.
Notes: Corners and perimeter area dimension shall not be less than a = 4'0"
