国家体育馆屋盖模型模拟地震振动台试验研究
|
摘要
传统的模拟地震振动台试验,由于受振动台台面尺寸的限制,平面尺寸一般不大,作者利用多子台振动台台阵系统对国家体育馆双向张弦梁结构屋盖模型(平面尺寸11.4m×14.4m)进行了竖向地震动振动台试验,通过试验得到了该结构在竖向地震动作用下的加速度、位移、应变响应及其响应规律,为评价国家体育馆屋盖结构在竖向地震作用下的抗震性能及今后同类结构的抗震设计提供了试验数据和依据.
Due to the limitation of the shake tables size,the model of traditional earthquake table test did not have the large size.This paper conducted a study on vertical vibration table test of the bi-directional beam string structure of the national gymnasium(plane size of 11.4 m×14.4 m)by the multiple vibration table array system.The responses and the rules of acceleration,displacement and stress of the structure under the vertical earthquake are gained,which can provide test data and basis to evaluate the seismic performance of national gymnasium roof and can be a reference for seismic analysis of similar structure in future.
