Abstract:Super high-rise structure of Guangzhou Financial City is a complex high-rise building exceeding B-level requirement of height in the code. There are irregularities including irregular torsion and partial discontinuity of floor. The performance-based seismic design method was adopted in the design. Different performance targets were proposed according to the importance of the components. The elasticity analysis under frequent earthquakes, the elastic time-history analysis under frequent earthquakes, elastic-plastic time-history analysis and stress analysis of the structure floor were performed. The analysis results show that the seismic performance of the whole structure and each component could reach the design target, and the structure system is safe and feasible. Finally the joints relevant to the concrete filled steel tube column designed in this project were introduced.
Keywords:super high-rise building; elastic-plastic time-history analysis; seismic performance; concrete filled steel tube
