摘要
本文采用大位移带刚臂梁－柱单元，分析并研究了结构节点刚性对由杆系拱加强的单层柱面网壳的稳定性的影响。文中对杆系拱－单层柱面网壳这种杂交结构体系进行了考虑及不考虑节点刚性的非线性大位移分析，并与试验曲线作了比较。结果表明，结构节点体系的刚性对单层网壳结构的稳定性的影响是值得注意的。
Abstract The effect of joint stiffness on stability of the single layer cylindrical reticulated shells reinforcedwith bararch is presented in this paper, in which the large displacement beam-column elements with rigidarms are use.The two structure cases, whether the joint stiffness is considered or not,are computed.Com-pared with test results, it is proved that the effect of joint stiffness on the structures should not be neglected.
