Abstract: The exterior steel structure of Museum of Contemporary Art and Plamung Exhibition of Shenzhen is an irregular lattice shell, and for lattice shells, especially for the single-layer lattice shells, the stability of lattice shells have become a key issue in the design. Based on the actual project, eigenvalue buckling analysis and all course tracing of the stability with ABAQUS generally finite element analysis program were carried out, and then considering initial imperfection, load cases and material nonlinearity on the influence of structural stability in this process. Finally a contrast analysis was done for the exterior steel structure before and after optimum design, and the conclusions and reasonable suggestions are given.
Keywords: stability; eigenvalue buckling analysis; lattice shells; initial imperfection; nonlinear
