Structural Design of Shenzhen Stock Exchange Plaza

摘要

Shenzhen Stock Exchange (SSE) plaza, being constructed in Shenzhen of China, is a complex high-rise building with a raised podium above ground level. The podium extends outwards from the tower structure at a maximum cantilever span of 36 meters. The lifted podium is a new concept conceived by architects but a big challenge confronting structural engineers. In this paper, the structural systems, including tower lateral resisting system, podium supporting system, floor system and foundation, are introduced. In order to evaluate the structural performance under the action of three earthquake levels specified by Chinese code, three models using MIDAS, ETABS and ABAQUS have been bui;the results from the three software presented. It has been shown that the performance targets of all three design earthquake levels can be attained.
