Abstract: Huaizhou New City International Exhibition Center is a particularly complex structure，a steel frame-central support structure with a circular plane base is adopted. The large-span and cantilevered roof adopt spatially twisted cross grid and single-layer reticulated shell structure. Based on the grid composition of the structural system and the foundation design, the introduction focuses on the integration of building, structure and curtain wall parameters, resolution of sudden changes in vertical stiffness, comfort of large-span cantilever, and collapse resistance analysis. The overall static, overall stability, seismic performance and BRB special design of the structure were analyzed and the corresponding seismic measures were taken for out-of-limit types. The results show that the whole structure is safe and reliable.
Keywords:Huaizhou New City International Convention Center； complex steel structure； cross grid； single-layer lattice shell； parameter integration； seismic performance-based design
