摘要
以有限元分析软件ANSYS为工作平台,基于非线性板壳有限元分析理论,采用大挠度弹塑性分析方法,对轻型门式刚架中H型钢梁相关屈曲性能进行了深入的研究,主要考察了残余应力对等截面H型钢梁相关屈曲性能的影响,获得到了一些有价值的结论。
Based on the finite element method, the interactive buckling of straight H-section steel beams used in portal frame structures are analyzed by ANSYS, in which geometric non-linearity and material non-linearity are considered and shell element is adopted. According to the load-deflection curves obtained, the effect of residual stress on the interactive buckling of straight H-section steel beams are discussed. Some valuable conclusions are drawn.
