| 摘 要： | 利用有限元法对L形截面钢异型柱轴心受压构件,在考虑非弹性和初始缺陷的基础上,进行了特征值屈曲分析和非线性屈曲分析,并将分析结果与规范柱子曲线进行了比较,从而证明了利用有限元法对实际L形截面钢异型柱进行分析是有效的。

| Abstract: | It was carried out an analysis of L-section steel column under axial load with the finite element method. Considering the influence of non-elasticity and initial imperfections,the buckling analysis of characteristic root and nonlinear buckling analysis have been conducted.The results of the buckling analysis have been compared with the column curve of the code.The finite element analysis of L-section steel column is proved to be effective. |
