In this paper, the advanced performance-based seismic theory is introduced, and combining with the seismic codes and high-rise building codes, a performance-based seismic design approach is established for high-rise frame-supported shear wall structure. Firstly, the performance objective is determined, and then calculation under frequent earthquakes, fortification earthquake and rare earthquake is carried out, finally, the performance analysis is carried out to see whether it achieves the predetermined performance objective. Then taking a high-rise frame-supported shear wall structure as an example, based on the performance-based seismic design method, YJK and ETABS software were used to carry out the performance-based seismic design under the action of frequent earthquakes and fortification earthquakes. Next, Perform3D software was used to analyze dynamic elastic-plastic time-history analysis under the action of rare earthquakes. In addition, the analysis of transfer component performance were conducted for quantitative control of the bearing capacity and deformation of reinforced concrete structures and structural members. The calculation results show that relevant parameters can meet code requirements and the seismic performance of the whole structure and components can reach the expected performance objectives. Finally, we present a summary of the proposed seismic strengthening measures and make suggestions for the whole structures, by which the structure can meet the seismic fortification code requirements and be safe and reliable.
