截面校核
腹板: h0/tw = 46.67 < 74.80 = (h0/tw)max; 翼缘: bef/t = 9.70 < 13.00 = (bef/t)max [5.4] 短截面
N/An + My/(gy*Wny) = 3.47 < 215.00 = f [5.2.1]
Tauz,max = 0.75 < 125.00 = fv [4.1.2]
构件稳定校核
Lamy = 30.91 < 150.00 = Lamy,max Lamz = 82.66 < 150.00 = Lamz,max [表5.3.7]
N/(Fiy*A) + Bmy*Mmaxy/(gy*W1y*(1-0.8*N/N'ey)) = 3.50 < 215.00 = f [5.2.2-1]
