Nonlinear Stability Analysis for Schwedler Reticulated Dome
On the base of finite element linear Eigen value analysis,overall stability analysis of Schwedler reticulated dome has 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 safer to adopt the nonlinear buckling analysis for structure.These can provide a valuable reference for the design and analysis of the similar special latticed shell.
