| 摘 要： | 本文介绍了一个鞍形单层网壳的模型试验。试验对该网壳结构内部16个节点采用位移控制法进行比例加载,得到了结构的屈曲后性能。同时,作者又采用分割有限元法编制了适用于网壳非弹性分析的计算机有限元程序,对该结构进行了精确的弹塑性全过程分析。分析与试验结果吻合良好。

| Abstract: | This paper describes the model test of a hyperbolic paraboloid latticed shell. Load was exerted on the 16 interior nodes by displacement control method, In this way the post buckling behavior of this structure was obtained. In order to investigate the elastic-plastic structural behavior, a nonlinear analysis program of latticed shells by using finite segment FEM has been compiled. The complete nonlinear process of the tested model is thoroughly studied by using this program. Analytical and experimental results agreed well with each other. |
