Abstract:Super high-rise tower building in AH040223 plot of Pazhou in Guangzhou is a complex high-rise building exceeding B-level requirement of height in the code. There are irregularities including irregular torsion, partial discontinuity of floor, and high-position plane setback. The performancebased seismic design method was adopted in the design. Different performance targets were proposed according to the importance of the structure. The elasticity analysis under frequent earthquakes, the elastic time-history analysis under frequent earthquakes, the performance design under fortification earthquakes, the equivalent elasticity analysis under rare earthquakes and elastic-plastic time-history analysis were performed. The analysis results show that the seismic performance of the whole structure and each component can reach the designed target. For the important components in place of high-position plane setback, the calculation and analysis and various structural measures were used to strengthen the components to ensure that the components meet the  seismic performance targets.

Keywords:super high-rise building; high-position plane setback; performance-based seismic design
