Abstract:Two super high-rise buildings (B&D) of Jiangdong Hexie Square are symmetric twin tower.  Frame-core wall hybrid structure with outriggers is adopted. The frame columns are concrete-filled rectangular steel tube columns. The structural system selection, performance-based seismic design and structural members design were introduced. The design of core wall, frame, story with outriggers and main measures adopted in special out-codes structures were presented. Seismic design and analysis of super high-rise buildings in the region of high earthquake intensity were focused on.
Keywords:super high-rise building; hybrid structure; concrete-filled rectangular steel tube column; seismic design
