PROJECT: Island Dunes Country Clubhouse — Entegra Bella High "S"
ADDRESS: 8735 S Ocean Drive Jensen Beach, Florida
2017 FBC/ASCE-7 DESIGN PRESSURE CALCULATIONS
Proiect Information:
Mean Roof Height = 25' Exposure: D Basic/Ultimate Wind Speed: V it 170 mph
Length= 36'to 101' Category: 11 Nominal Wind Speed: V.d=Vint*40.6
Width = 23' to 85' Slope: 3/12 to 6/12 (asd = allowable strength design)
Parapet Wall: N/A Clubhouse & = 1.12, Kzt =1.0, Kd = 0.85
Note: The most conservative dimensions were utilized for the design calculations below.
Design Calculations:
Velocity Pressure: q = 0.00256*K KzXdV2
Velocity Pressure (,do: q=0.00256(1.12)(1.0)(0.85)(170)2] = 70.43 psf
Velocity Pressure (.d): q=0.00256(1.12)(1.0)(0.85)(170*40.6)2] = 42.26 psf
Width of Pressure Coefficient: 0.1(85') = 8.5'
0.4(25') = 10.0' } use: 8'6"
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

Onshore Roofing
Island Dunes Country Clubhouse
Sloped Tile (Bella High "S") Roof
8735 S Ocean Drive; Jensen Beach, Florida:
Design Pressures Based on Vasd:
1) Field Pl = 42.26*[(-0.9) — (0.18)] = -45.6 psf
2) Perimeter P2 = 42.26* [(-1.7) — (0.18)] = -79.4 psf
3) Corners P3 = 42.26* [(-2.6) — (0.18)] = -117.5 psf
Attachment Requirements Per RAS 127 (Entegra Bella High "S" Tilel:
Tile System: Moment Based
Aerodynamic Multiplier: 0.378 f0 (Direct Deck Application - Table 1)
Restoring moment due to gravity: Mg = 6.51 ft. lb (Table 2)
Attachment resistance expressed as a moment: Mf= 94 ft-lb Polyset AH-160 Adhesive
Set (Table 4, Independent Large Paddy 63g)
1) Field : Mrl = ( 45.6*0.378) — 6.51 ft. lb =10.7 ft. lb. < 94 ft. lb = PASS
2) Perimeter: Mr2 = ( 79.4*0.378) — 6.51 ft. lb = 23.5 ft. lb. < 94 ft. lb = PASS
3) Comers : Mr3 = (117.5*0.378) — 6.51 ft. lb = 37.9 ft. lb. < 94 ft. lb = PASS
System is acceptable as approved with single independent large paddy (63g) placement of
Polyset AH-160 (by ICP Adhesives and Sealants) based on the requirements of Florida
Product Approval FL7804-R10.
Notes: Corners and perimeter area dimension shall not be less than a = 8'6"
