| 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. |
