Abstract:Huamin Imperial Tower adopts the frame-corewall hybrid structural system with outriggers. Concrete-filled rectangular steel tube(CFRT) columns and steel reinforced concrete(SRC) columns are used in the periphery. The structural system characteristic, performance-based seismic design principle and method, the main results of elasticity analysis, Pushover analysis under the action of rare earthquake and the design of building foundation were introduced systemically. Some key problems were expounded, including the core wall with concealed bracings and SRC, SRC frame and CFRT structure in the periphery, inclined columns transfer structure with CFRT member and story with outriggers.

Keywords:super-high hybrid structure; performance-based seismic design; Pushover analysis; transfer story
