Abstract: China Yellow Sea Wetland Museum is reconstructed based on the original railway station. The lower structureadopts a frame + BRB structure, and the upper roof adopts a large-span truss-reinforced reticulated shell structure. Thesimplified model was compared for the type selection and optimization of large-span roof. The two schemes of hinged andrigid connection at the bottom of the lattice column were discussed. The overrun judgment and counter measures, theoverall stability of steel roof and ability to resist continuous collapse, and the reinforcement scheme of lower main structurewere introduced. The results show that the truss-reinforced reticulated shell structure combines the advantages of truss andreticulated shell structure and the overall stability and continuous collapse resistance of steel roof are good. The vertical andhorizontal stiffness of the saddle-shaped roof is much greater than the flat roof. The advantages of the truss-reinforcedreticulated shell structure and the saddle-shaped shape are fully utilized in the design to achieve a large-span space using asmall height of the structure.

Keywords:China Yellow Sea Wetland Museum; large-span space structure; truss-reinforced reticulated shell structure;overall stability; continuous collapse resistance; arch foot thrust; structural reinforcement
