摘　　要：利用双重非线性壳体有限元方法 ,对偏心受压钢构件在循环荷载作用下的滞回性能进行了计算机模拟 ,分析了H形截面偏心受压构件的滞回特性 ;得出了强烈地震作用下 ,构件翼缘宽厚比、腹板高厚比。Computerized model of hysteretic behavior of the eccentric compressive steel structure members under cyclic loading is carried out based on geometric and material nonlinear finite element method.The hysteretic characteristics of H section eccentric compressive steel structure members are analysed. The impact law of width to thickness ratio of flange,height to thickness ratio of web,axial compression ratio and slenderness ratio on hysteretic behavior of the H section eccentric compressive structure members under a strong seismic action are obtained.
