Procedure 4-1 Wind Design Per ASCE

Fi = design wind force of section under consideration, i = 1 to n, lb (N) gQ = peak factor for background response, use 3.4 

G = gust effect factor Gf = gust response factor for flexible vessels 

Kd = wind directionality factor, use 0.95 for vessels when using ASCE/SEI 7-10 load combinations Kz = velocity pressure exposure coefficient from Table 4-3a 

Kzt = topographic factor, use 1.0 unless vessel is located near or on isolated hills. See ASCE/SEI 7-10 for specific requirements
