Single-layer special-shaped folded-plane latticed shell had been applied in Shenyang culture and art center. In order to analysis its static stability, explore the form of buckling modes and find out its critical load factor, this paper analysis the optimized structure with MIDAS Gen. Eigenvalue buckling analysis and nonlinear buckling analysis showed that the in-plane stiffness of the structure is very large, and the out-plane stiffness is small, the upside structure is prone to instability. The critical load factor for this structure is 10.32, the structural overall stability is fine according to the code. This structures is sensitive to the initial geometric imperfections which could lower structural stability of the system.
