| Abstract: | In this paper, the nonlinear FEM is used to analyze the general stability of torsional shell and torsional reticulated shell with original imperfections. The modality of stability and the critical loads at critical condition are obtained. Through the analysis of examples, some regularity has been found and may be used as a reference in engineering. |
