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 performance test of 1:10 large-scale model of the Olympic badminton court building was completed by the nine-son array system. The multi-order natural frequency, mode shape and damping ratio of the model were measured by artificial sinusoidal excitation and environmental excitation. Through the shaking table test, the acceleration, displacement, strain response and response of the model under the action of ground motion are obtained. The test results show that the material is always in the elastic phase under the action of 8 degree earthquake and the structure has good anti-seismic performance.
