Abstract:The main tower of Zhuhai Onelink World Center is 340-6m high. The concrete-filled steel tubular column frame and concrete-filled steel tubular corewall structural system with strengthened story and high-level transfer layer was adopted. The project is located in the coastal area with strong wind, and the project has large aspect ratio, high-level transfer, and concrete-filled steel tubular shear wall. In the course of structural design, analyses were conducted such as the  elastic analysis under frequent earthquake, stability analysis, axial compression ratio analysis of steel tubular shear wall, wind load analysis, high-level transfer story analysis, shear bearing capacity analysis between stories, and dynamic elastic-plastic analysis under rare earthquakes. The performance-based design method was adopted for structural seismic design, which realized the preset C-level seismic performance target.

Keywords:Zhuhai Onelink World Center; out-of-code high-rise building; concrete-filled steel tube; aspect ratio; overall stability; high-level transfer; strengthened story
