摘　　要：利用有限元软件ANSYS对圆管钢结构进行了稳定性分析,并且界定出该分析方法的适用范围,为该类钢结构稳定性的数值分析和设计提供了依据。分析主要采用特征值屈曲方法,将经ANSYS特征值屈曲分析得出的结果与经验公式和欧拉公式得出的结果相比,发现ANSYS屈曲分析方法必须在一定条件下才适用于解决稳定性分析问题。The finite elements software ANSYS was applied to stability analysis on tubular steel,and the applicability of the method was defined.It provides some experience to the buckling analysis of these kinds of steel structure.The main research method was eigenvalue buckling analysis.The results were then compared with eigenvalue buckling analysis and euler formulas.It was found that eigenvalue buckling analysis is available to solve the buckling problems under the limit of certain conditions.

关 键 词：圆管钢 特征值屈曲 非线性屈曲
