一、组合结构的总体弹性屈曲分析 结构的稳定性分析是工程结构设计中的一个十分重要的问题。对于形状或外荷载复杂的结构,尤其是组合结构,往往不易甚至不可能用经典的解析方法求得其精确解答。因此,用有限元法进行组合结构的屈曲分析是一条有力的途径。本文在多单元组合结构分? First, the overall elastic buckling analysis of the composite structure Structural stability analysis is a very important issue in the engineering structure design. For structures with complex shapes or external loads, especially composite structures, it is often difficult or even impossible to obtain a precise solution using classical analytical methods. Therefore, the buckling analysis of the combined structure using the finite element method is a powerful approach. This paper is divided into multiple unit combinations.
