Column axial force of dead loads Na=1.5x3203.78=4806kN; Nb= Nc = 1X3203.78=3204kN; Nd=0.5x3204=1602kN; Ne=2x3204=6408kN 3. Column axial force of wind load in main wind direction, Nb=Ne=0 4.5Ndx60x0.305=20x47.84x8x3mx80x0.305x12m, Nd=Nc=81.65kN,Na=0.5x81.65=40.83kN 4. Column axial force of wind load in another direction if Na=x,Ne=Nc=3x,Nd=7x, 60x0.305x24x12x20x47.84=2Nax0.305(7x140+5x100+3x60+1x20) Na=4.92kN, Ne=Nc=14.76kN, Nd=34.44kN, 0.5Nb=34.44x2/1.5/2=22.96kN 5. Column axial force of wind load in another direction 1.5Nbx60x0.305+1.5(Nb/3)x20x0.305=60x0.305x24x12x20x47.84, 0.5Nb=0.5x(180.69)=90.34kN Therefore Nb=22.96+90.34=113.3kN, Ne=0.5x180.69/3+0.5x14.76x2/1.5=30.12+9.84=39.96kN Na=90.34+0.5x4.92x2/1.5=93.62kN 6. The Maximal Wind Load: Na=93.62kN, Nb=113.3kN,Nc=81.65kN,Nd=81.65kN,Ne=39.96kN
