钢压弯构件截面的选择方法

Method for choosing the section of press-bending steel member

通过对压弯构件的强度、平面内和平面外稳定性计算公式联立求解,得出对截面主轴的强轴截面惯性矩Ix,结合假定长细比试选压弯构件的截面,计算工作量较小,可供设计参考。

By solving the combined formulas on strength and stability for both inside and outside plane of pressbending steel member, obtain the crosssection inertia moment (Ix) to the main axis, then try to choose the section of pressbending steel member in conjunction with assumed slenderness ratio, with less amount of calculating work, it may be referred in design
