( Xian Dai Architectural Design Group, Shanghai Institute of Architectural Design & Research Co. , Ltd., Shanghai 200041, China)Abstract: The Tian' an peninsula project was a multi-tower structure based on a whole podium, which was out of the range of Chinese aseismic code. The analysis method and earthquake resistant constructional measure was introduced. Some analysis processes were described in detail, including elastic time-history analysis, pushover analysis and the enlarged base floor slab stress analysis. The experience in this project could be an useful reference for similar structure.
Keywords: multi-tower structure; enlarged base; static elasto-plastic analysis; aseismic design methods
