Abstract: Taking the design of Hainan Ball for example, the key points of the overall structural design and calculation were summarized for the schwedler type single-layer lattice shell structure. The structural type selection, stability of the single-layer lattice shell, seismic performance and the reinforcement solution of a large hole opened in the project were discussed. The nonlinearoverall stability analysis of the project was carried out, and the impact of the amplitude of initial imperfection on the overall stability was analyzed. Some recommendations of the reasonable value of the amplitude of initial imperfection were given.

Keywords: schwedler type single-layer lattice shell; initial imperfection; nonlinear-overall stability analysis
