( Suzhou Industrial Park Design & Research Institute Co., Ltd., Suzhou 215021, China)Abstract: Suzhou Modem Media Square Office is high-rise buildings with height of 214. 8m,tower and podium are connected together into a whole, framework-core tube structure system is adopted for the tower. The structural basic design of the project was described. Because there were a number of indicators overrun characteristics, the feasibility of the structural system based on performance-based seismic design method was demonstrated. Beside the conventional structure calculation and analysis, elastic-plastic analysis was used to verify its seisnuc performance. According to above results appropriate technical measures were proposed.
Keywords: frame-core wall; super high rise structure; performance-based; rare earthquake
