Abstract:The No.2 tower building of Cuihu Xiangshan International Garden in Zhuhai is a  high-rise building, which adopts frame-supported shear wall structure that exceeds B grade height requirement of the code. Combined with the engineering characteristics and out-of-code conditions, a performance-based seismic design method was adopted. The programs of YJK, ETABS and PKPM-SAUSAGE procedures were applied to carry out the performance-based design under  the frequent earthquake, fortification earthquake and rare earthquake. Stress analysis was conducted on the frame-supported transfer in the structure. According to the analysis results, a series of strengthening measures were adopted. The results show that the structure has well seismic performance, and it can realize the performance objective under the rare earthquake.

Keywords:out-of-code high-rise building;  frame-supported shear wall structure; secondary beam transfer; performance-based design; dynamic elasto-plastic analysis; stress analysis
