Abstract: The tower building of a super high-rise office building in Nanjing Jiangbei New Area adopts steel reinforcedconcrete frame-reinforced concrete core-wall structural system. The plane of the project is relatively regular, and there is noobvious mutation in the vertical stiffness and bearing capacity. Meanwhile, it is an out-of-code mixed structure with severalirregular items, such as torsional irregularity, concave convex irregularity and local irregularity. Combined with the factorssuch as seismic fortification category and intensity, structure system and height, different seismic performance objectiveswere formulated based on different performance levels during design. The overall stress condition of the structure wereanalyzed and the key components and jointing nodes such as bifurcated columns were designed. The analysis results showthat the overall structure of tower building is safe, reliable, economical and reasonable, and each key component andjointing node can meet the design requirements.
Keywords: super high-rise building; mixed structure; out-of-code structure; bifurcated column; inclined column;performance-based seismic design
