STUDY ON PERFORMANCE-BASED SEISMIC DESIGN OF SHANGHAI WORLD FINANCIAL CENTER TOWER

摘要

The height of 101-storey Shanghai World Financial Center Tower is 492m above ground. According to the philosophy of performance-based seismic design, the seismic performance design objectives and corresponding parameters were proposed for the structure under various seismic actions from frequent to rare earthquake levels. Analytical studies including refined finite element analysis, nonlinear time-history analysis, and stress distribution analysis on the important joint have been conducted to evaluate the structural seismic performance. Along with the analytical studies, shaking table model test and the important joint tests have been carried on in order to verify the accuracies of the analytical results as well as to complement the analytical studies. The results obtained from the studies demonstrate that the structural system meets the performance-based design objectives presented in the paper.
