Gust Factor Calculations.'
Gust Factor Category I Rigid Structures - Simplified Method
r
Gustl: For Rigid Structures (Nat. F eq.>1 Hz) use 0.85 = 0.85
y
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 = 0.93
Gust2: 0.925*((1+1.7*lzm*3.4*Q)/(1+1.7*3.4*lzm)) = 0.89
Gust Factor Summary
Not a Flexible Structure use the Lessor of Gustl or Gust2 = 0.85

Notes Applying to MWFRS Reactions:
Note (1) Per Fig "27.4-1, Note 9, Use greater of Shear calculated with or without roof.
Note (2) X= Along Building ridge, Y = Normal to Building Ridge, Z = Vertical
Note (3) MIN = Minimum pressures on Walls - 9.6 psf and Roof = 4.8 psf
Note (4) MIN area is the area of the surface onto a vertical plane normal to wind.
Note (5) Total Roof Area (incl OH Top) = 1849.35 sq. ft .
