薄壁结构力学性能分析的一维模型,用于分析一些框架结构的初始后屈曲性能。该模型以一种非常简单的方式考虑了翘曲的初始边界条件,而且被证明是分析薄壁框架结构的一种有效模型。基于多物理场耦合分析软件的有限元法,给出许多L型框架的数值分析结果。
A one-dimensional model of mechanical properties analysis of thin-walled structures was used to analyze the initial post-buckling performance of some frame structures. The model considers the initial boundary conditions of warping in a very simple way and has proven to be an effective model for the analysis of thin-walled frame structures. Based on the finite element method of multi-physics coupling analysis software, numerical results of many L-shaped frames are given.
