Abstract: Chongqing Tower is a super high?rise building with a total height of 430m. The architectural shape is large at thebottom and small at the top. It adopts a concrete?filled steel inclined column frame?core tube?ring belt truss structure systemwithout outrigger reinforcement. The characteristics of the engineering structure and the selection of the structural systemwere expounded, and the corresponding seismic measures and seismic performance targets were put forward for theover?limit situation. According to relevant specifications and wind tunnel tests, the structural design scheme and overallperformance were studied in detail. The conversion of inclined wall, comparison and selection of reinforcement layers,calculation of length of large?diameter concrete?filled steel column, and analysis of anti?continuous collapse were discussed.The results show that the seismic performance of the whole structure and its components can reach the expected targets, theresults of progressive collapse analysis meet the requirements, the structure system is safe and feasible.
Keywords:concrete?filled steel inclined column; ring belt truss; conversion of inclined wall; reinforcement layer;anti?continuous collapse
