PROJECT: Horbacz Residence 26 Gauge 5V Crimp Roof Panel
ADDRESS: 63 Flores Del Norte Fort Pierce, Florida
FBC 2014/ASCE 7-10 DESIGN PRESSURE CALCULATIONS
Project Information:
Mean Height= 15' Max. Exposure: C Basic/Ultimate Wind Speed: V„It=170 mph
Length= 62' Category: II Nominal Wind Speed: Vasd=Vi1t*40.6
Width= 25' Slope: 2.4/12= 11° (asd=allowable strength design)
Parapet Wall: N/A Residential K,= 0.85, Kzt= 1.0, Kd= 0.85
Design Calculations:
Velocity Pressure: q= 0.00256*KZKztKdV2
Velocity Pressure (u1t): 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(25') = 2.5'
0.4(15') = 6.0' } use: 3'0"
Effective Wind Area: <1 Of 2
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 = 32.07*[(-0.9)—(0.18)] _-34.6 psf
2) Perimeter P2 = 32.07*[(-1.7)—(0.18)] _-60.3 psf

patterns and these fastener row spacings:
Area Field,Perimeter& Corners
Maximum Total Uplift Design Pressure -108.5psf
Fastener Pattern Panel Ribs (12" o.c.)
Fastener Pattern Spacing 12" O.C.
*NOTE: Due to roof slope less than 3:12, lap sealant must be used in all panel side laps
Notes: Corners and perimeter (edge, hip, & ridge) area dimension shall not be less
than a = 3'0" (Zone 2: Perimeter (including along ridges) is a 3'0" wide
strip, Zone 3: Corners are 3'0" x 3'0")
Contractor to verify that the fastening patterns meet manufacturer's
requirements for issuance of a warranty (as applicable).
All work shall be in compliance with the local building code product control
notice of acceptance and manufacturer specifications and Florida Building
