摘　　要：利用九子台阵系统完成奥运羽毛球馆弦支穹顶结构1:10大比例模型的抗震性能试验。利用人工正弦激励和环境激励两种方法测得模型的多阶自振频率、振型、阻尼比。通过振动台试验得到模型在地震动作用下的加速度、位移、应变响应及响应变化规律。试验结果表明:场馆在8度大震作用下,材料始终处于弹性阶段,结构具有良好的抗震性能。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.
