Basic Wind Speed(V) = 170.00 mph
Structural Category = II Exposure Category = D
Natural Frequency = N/A Flexible Structure = No
Importance Factor = 1.00 Kd Directional Factor = 0.85
Damping Ratio (beta) = 0.01
Alpha = 11.50 Zg = 700.00 ft
At = 0.09 Bt = 1.07
Am = 0.11 Bm = 0.80
Cc = 0.15 1 = 650.00 ft
Epsilon = 0.13 Zmin = 7.00 ft
Pitch of Roof = 0 : 12 Slope of Roof(Theta) _ .00 Deg
h: Mean Roof Ht = 200.00 ft Type of Roof = MONOSLOPE
RHt: Ridge Ht = 200.00 ft Eht: Eave Height = 200.00 ft
OR: Roof Overhang at Eave= .00 ft Overhead Type = No Overhang
Bldg Length Along Ridge = 180.00 ft Bldg Width Across Ridge= 80.00 ft
Gust Factor Calculations
Gust Factor Category I Rigid Structures - Simplified Method
Gustl: For Rigid Structures (Nat. Freq.>1 Hz) use 0.65 = 0.85
Gust Factor Category II Rigid Structures - Complete Analysis
Zm: 0.6*Ht = 120.00 ft
lzm: Cc*(33/Zm)^0.167 = 0.12
Lzm: 1*(Zm/33)^Epsilon = 763.83 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)) = 0.87
Gust Factor Summary
Not a Flexible Structure use the Lessor of Gustl or Gust2 = 0.85
