Abstract: The Shanghai International Financial Center Project consists of three parts, namely Shanghai Stock Exchange(SSE), China Financial Futures Exchange (CFFEX) and China Securities Depository and Clearing Corporation Ltd(CSDCC). The towers with respective heights of 220m, 200m and 163m are connected by a light bridge construction at floors 07, 08 and 09. Elastoplastic dynamic analyses under rare occurred earthquake are conducted by the Abaqus software. Stmctural performance of the displacement and mechanical behavior are evaluated during analysis on different connection forms of the corridor bridge. The methods and results presented in this article offer reference to the design of this project and can also be used for other similar structural designs.
