( Suzhou Industrial Park Design & Research Institute Co., Ltd., Suzhou 215021, China)Abstract: The high-rise apartment building twin-towers were used outside the double frame-core tube structure system, the structure of tlurd layers of steel structure truss tower set conjoined as between the horizontal transport hub. According to the structure gauge, using the method of performance based seismic design and bearing capacity and deformation, calculated structure and component seismic performance under rare occurred earthquake. According to the results of the analysis, put forward corresponding design measures to making that structure can aclueve predetemuned performance target. This paper can provide technical reference for similar high rise structure.
