摘要
本文首先提出了结构做有限元剖分后的网络化方案,利用文中所定义的边刚度矩阵的概念,分析了节点力平衡和变形协调条件的表达式,导出了与有源网络节点方程完全相同的总刚度方程,并论证了方法的合理性。实现了网络方法与结构有限元方法的结合。
This paper firstly proposes a scheme of network representation for discreted structure, then analyses representative formulation of nodal forces equilibrium condition and displacement compatibility condition with the concept of edge-stiffness matrix which is defined in this paper.According to such as above, the total stiffness equation,which is the same as the nodal equation of active network, is derived. This gives a way to conjugate the finite elements method with the network analysis mothod.
