ASCE 7-16 DESIGN PRESSURE CALCULATIONS
-- ----- In Accordance with Chapter 30,Part I - TOLE py
Proiect Information: Sloped Wood Deck Roof
Height= 25' Exposure: C Ultimate Windspeed: V„u=:170 mph
Length= 100' Category: H Basic Windspeed: Vnd = 132 mph
Width= 95' Slope: 9:12 KZ= 0.95 Kd=0.85

Design Calculations:
Velocity Pressure: q = 0.00256*[(0.95)(0.85)(1.00)(1.00)(132)2]
=35.8 psf
Width of Pressure Coefficient Zone: 0.1(95') = 9.5'
0.4(25') = 10.0' } use: a= 9'6"
Effective Wind Area: <10ft2
For parapet height three feet(3')or larger,zone three(3)can be treated as zone two(2) (ASCE746).
External Pressure Coefficient: Internal Pressure Coefficient
1) GCPl = -1.5 1) GCPi = 0.18
2e) GCP2e = -2.5
2r) GCP2r = -2.8
3) GCP3 = -3.6
Design Pressures:
1) Field P1 = 35.8*(-1.5—0.18)= -60.2 psf
2e) Perimeter Ridge: P2e= 35.8*(-2.5—0.18)= -96.1 psf
2r) Perimeter Eave : P2r= 35.8*(-2.8—0.18)= -106.8 psf
3) Corner P3 = 35.8*(-3.6—0.18)= -135.5 psf

i
Zone 1: #10 x 1" fasteners spaced at 6" o./c. along nail strip (Method A)
Zone 2r: #10 x 1" fasteners spaced at 5" o./c. along nail strip (Method A),
p g p (M )
Zone 2e: #10 x 17 fasteners spaced at 5" o./c.along nail strip (Method A)
i
Zone 3: #10 x 1" fasteners spaced at 5" o./c.along nail strip (Method A)
Notes: Corners and perimeter area dimension shall not be less than a=9.5' '
Fasteners are installed through the metal flange,not through the pre-punched slots.
All work shall be in compliance with the local building code product control notice of
acceptance and manufacturer specifications and the Florida Building Code 2020.
Wind load calculations based on ASCE 7-16 and information provided by client.
All work shall be inspected by our field engineer or city inspectorp verify compliance
with specifications.
