| 摘 要： | 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。

| Abstract: | A finite element program designed for the stress analysis of ribbed shells is presented. In this paper, the stiffness matrices and load vectors of the beam elements have been transformed so as to get the nodal displacements of each beam element compatible with those of the adjoining shell elements. The wavefront solution method has been adopted to solve the system of equation, thus the microcomputer may be used to analyze a mediumscale structure. As an example of its applications, the ribbed shell of the astronomical observatory of wuxi children's palace is computed in the way. |
