ANTI-SEISMIC PERFORMANCE EXPERIMENT ABOUT THE SUSPENDOME STRUCTURE OF BADMINTON GYMNASIUM FOR 2008 OLYMPIC GAMES

The seismic behaviors experiments of the Olympic Games badminton gymnasium suspendome structure 1∶10 model by the multiple vibration table array system were conducted in this paper. Frequencies of different mode steps，modes and damp ratios of the model were tested by ambient excitation method and sine excitation method. The responses and rules of acceleration，displacement and stress of the structure under the earthquake were gained. The experiment results indicated that material of the structure was in elastic phase，and had good anti-seismic performance under 8 degree strong earthquake.
