针对脚手架工程常用的钢管进行了有限元模拟,用ANSYS有限元软件模拟了该杆件在特定工况下的失稳情况,并进行了特征值理论计算、特征值屈曲计算及非线性屈曲分析,进而得出不同程度初始缺陷对杆件稳定性能的影响程度。%This paper carries out finite element analysis for the steel pipe used in scaffold engineering,simulates instable condition of the member under certain working condition by using ANSYS finite element software,and carries out eigenvalue theory calculation,eigenvalue buckling calculation and nonlinear buckling analysis,and obtains the influential degree of preliminary defect with different degrees upon the member stability performance.
