Abstract: Shizimen Iconic Tower has an architectural height of 322.9m with total 61 stories. The main structural system is mixed structure with steel reinforced concrete and frame-reinforced concrete of composite frame-core tube with outriggers and belt members. The tower is out-of-code high-rise building with a number of structural irregularity indexes, such as the member of discontinuous, outer frame inclined columns, and frame-core tube with inclined shear wall to achieve cylinder setback. Performance-based seismic design method was used in this tower. The research shows that relevant parameters can meet the code requirements, and the seismic performance of whole structure and each structural member can reach the expected objective.

Keywords: mixed structural system; inclined column; inclined shear wall; story with outrigger and belt member; performance-based seismic design
