【摘要】 在有限元线性屈曲分析基础上,采用有限元非线性分析理论对施威德勒型球面网壳结构的整体稳定进行了全过程分析。应用弧长法求解非线性方程,得到了该球面空间网壳结构整体稳定的全过程荷载-位移曲线,为此类网壳的设计和分析提供了有价值的参考。更多还原

【Abstract】 On the base of finite element linear eigen value analysis,overall stability analysis of Schwedler reticulated dome have been conducted by means of the nonlinear finite element method.The arc-length method was utilized to solve the nonlinear equation systems,and the load-displacement curves of the spatial latticed shell structure were obtained.It is a valuable reference for the design and analysis of the similar special latticed shell.更多还原
