摘要
考虑不同长细比、初弯曲和翘曲是否约束的影响,采用有限元软件ANSYS计算L形柱轴心受压时的极限荷载,总结出φ曲线的简便计算公式,进而得到φ-λ曲线与《钢结构设计规范》(GB50017-2003)中曲线的比较,以期为L形柱的合理设计提供参考。
Considering the effects of different ratios of slenderness , initial bending and warping ,ultimate load of the L-shaped column under axial compression is calculated by ANSYS. The simple formulae for φ curve are gained, and the φ-λ^- curves are compared with that of the code. Some conclusions may be referenced for the reasonable design of the L-shaped columns.
