The structural height of its main roof is 148.7m, and the height of core wall is 157.1m. The height is beyond the height limit of grade A (130m) concrete structure 18.7m, about 14.4%, but under grade B height limit (180m), and the height limit of mixed structure (160m). General elastic analysis under frequent earthquake are performed by SATWE and MIDAS BUILDING, the bearing capacity of the structure under fortified earthquake is checked, the elastic-plastic time-history analysis under rare earthquake is carried by MIDAS BUILDING. The floor span between two core walls is 16.1m, using the MIDAS GEN to analyze its comfort level. Based on the analysis, the corresponding structural measures are used to reach the target of performance-based seismic design. At present, the project has passed the preliminary design and construction drawing review.Keywords：Steel frame-reinforced concrete core wall; comfortable degree; performance-based seismic design
