Input Parameters: Directional Procedure All Heights Building (Ch 27 Part 1)
Basic Wind Speed(V) = 165.00 mph
Structural Category = II Exposure Category - D
Natural Frequency = N/A Flexible Structure - No
Importance Factor 1.00 Kd Directional Factor - 0.85
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 - 75.00 ft Type of Roof - FLAT
RHt: Ridge Ht = 75.00 ft Eht: Eave Height = 75.00 ft

Gust Factor Calculations
Gust Factor Category I Rigid Structures - Simplified Method
Gustl: For Rigid Structures (Nat. Freq.>1 Hz) use 0.85 - 0.85
Gust Factor Category II Rigid Structures - Complete Analysis
Zm: 0.6*Ht = 45.00 ft
lzm: Cc*(33/Zm)^0.167 0.14
Lzm: 1*(Zm/33)^Epsilon = 675.69 ft
0: (1/(1+0.63*((B+Ht)/Lzm)^0.63))^0.5 = 0.87
Gust2: 0.925*I(1+1.7*lzm*3.4*Q)/(1-+1.7*3.9*]zm)) = 0.87
Gust Factor Summary
Not a Flexible Structure use the Lessor o£ Gustl or Gust2 = 0.85
