Stability analysis of a new type reticulated shell

The elastic and elastic-plastic overall stability problems are analyzed for the reticulated shell used in 2010 Shanghai Expo-axis, and studies are made to contrast and analyze the calculated results corresponding to different parameters so that the effects on the overall stability of structures caused by the material model assumption and initial geometric imperfections are obtained, and at last the paper presents the deficiency of current specifications when used for the new type reticulated shell and points out some pressing problems.
