State : FL Proj Location : 5720 Spanish River Rd.
Ft. Pierce, FL 34951
Input Parameters: Directional Procedure All Heights Building (Ch 27 Part 1)
Basic Wind Speed(V) = 170.00 mph
Structural Category = II Exposure Category = C
Natural Frequency = NIA Flexible Structure = No
Importance Factor = 1.00 Kd Directional Factor = 0.85
Alpha = 9.50 Zg = 900.00 ft
At = 0.11 Bt = 1.00
Am = 0:15 Bm = 0.65
Cc = 0.20 1 = 500.00 ft
Epsilon = 0.20 Zmin = 15.00 ft
Pitch of Roof = 2.865672 12 Slope of Roof(Theta) = 13.43 Deg
h: Mean Roof Ht = 25.00 ft Type of Roof = HIPPED
RHt: Ridge Ht = 33.00 ft Eht: Eave Height = 17.00 ft
OH: Roof Overhang at Eave= 2.00 ft Overhead Type = OH w/ soffit
Bldg Length Along Ridge = 140.00 ft Bldg Width Across Ridge= 130.00 ft
Length of Hipped Ridge = 50.00 ft Roof Slope on Hip End = 18.80 Deg
Gust Factor Calculations
Gust Factor Category I Rigid Structures - Simplified Method
Gustl: For Rigid Structures (Nat. Freq.>l Hz) use 0.85 = 0.85
Gust Factor Category II Rigid Structures - Complete Analysis
Zm: 0.6*Ht = 15.00 ft
lzm: Cc*(33/Zm)^0.167 = 0.23
Lzm: 1*(Zm/33)^Epsilon = 427.06 ft
Q: (1/(1+0.63*((B+Ht)/Lzm)^0.63) )^0.5 = 0.87
Gust2: 0.925*( (1+1.7*lzm*3.4*Q)/(1+1.7*3.4*lzm)) = 0.85
Gust Factor Summary
Not a Flexible Structure use the Lessor of Gustl or Gust2 = 0.85

*Window Replacement using existing shutters to comply with impact protection will require the
existing shutters to meet the requirements of the 2010 FBClResidential R301.2.1.2
TOTAL GLAZED OPENING AREA FOR 8TRUCTRE: 8.F.
PERCENTAGE OF NEW GLAZED AREA:
(TOTAL INSTALLED GLAZED AREA DIVIDED BY TOTAL GLAZED OPENINGS FOR STRUCTURE)
NOTE:The replacement of more than 25 of the aggregate area of exterior glazing(windows&doors)in one&two family
dwellings within a 12 month period will require impact protection on all proposed glazed opening replacement(approved shutters
or impact resistant glazing)as per 2010 FBCI EXISTING BUILDING 606.1.
