我们编制了用于肋壳结构分析的有限元程序。本文对梁单元的刚度矩阵和载荷向量进行了变换,以实现各个梁单元的节点位移同与其连接的壳单元的节点位移的协调。采用波前法解方程组,因此可用微机分析中等规模的结构。应用该程序对无锡少年宫天文台的肋壳结构进行了计算。
We have compiled a finite element program for the analysis of the shell structure. In this paper, the stiffness matrix and the load vector of the beam element are transformed to realize the coordination of the node displacement of each beam element with the joint displacement of the shell element connected with it. The wavefront method is used to solve the equations, so a medium-sized structure can be analyzed with a microcomputer. This program was used to calculate the rib structure of the Wuxi Children’s Palace Observatory.
