Abstract: This project is located in Wuhua district of Kunming city, and Tower A is a general irregular super high-rise building with a structural height of 149.8 meters, which adopts reinforced concrete frame-core wall structure with a outrigger story. According to the selected seismic performance objective, performance analysis was conducted for the structure under different seismic performance levels. The analysis result shows that with appropriate measures, the performance objectives of the structure can meet the predetermined levels at different stages. Additional calculation and analysis were conducted for the floors with big opening, the cross-layer columns, temperature conditions and the outrigger truss. Specific strengthening measures were proposed according to the analysis result at different levels. The study of this paper can provide reference to the structure design of similar super high-rise buildings in the regions with seismic fortification intensity of 8 degree.

Keywords: performance-based seismic design of structure; frame-core wall structure; story with outriggers
