Abstract: Zhengzhou International Cultural Exchange Center is a complex out-of-code high-rise building with a novelarchitectural shape, it includes a large-span arch-supported structure at the main entrance, and multi-stories withlarge-span floors in the interior space to connect the nearby structural units with large-span connected structural units. Themain building adopts steel frames with concentrically braces structural system. The structural scheme selection and thedesign strategies against the out-of-code characteristics were mainly introduced, the structural designs points of the giantarch at the main entrance, the connected viewing platform and the connected structural units in the air were emphasized.The corresponding structural analysis softwares were used to carry out the seismic actions at different levels, seismicperformance analysis, giant arch stability analysis and key joint analysis for the structure. The analysis results show that theforce transfer of the structural system is clear, and the overall structure is safe, reliable and economic.

Keywords:Zhengzhou International Cultural Exchange Center; giant arch; connected structural unit; steel frames withconcentrically braces; performance-based design
