Abstract:The high-rise building on plot C-02 in Tianjin Xiangluowan is 238 meters high with 54 stories above\|ground. The building is supported by concrete-filled steel tube frame-RC core system. Strengthened stories with outriggers are set at refuge stories and roof story. The structural arrangement and earthquake resistance objectives, main results of calculation and analysis, measures to strengthen the structure under earthquake were introduced. The structural design of the tower has satisfied the requirements of the building beyond-code, which can ensure the safe and economic the structure. The preliminary design of the project has gone through the seismic examination.
Keywords:high-rise building beyond-code; composite structure; concrete\|filled steel tube; strengthened story; outrigger
