国家体育馆屋盖模型二维地震反应试验研究
Two-dimensional earthquake test study on roof model of National Gymnasium
【摘要】 国家体育馆双向张弦屋盖模型模拟地震振动台试验是国内外首次进行的如此大尺寸空间结构的试验,作者进行了竖向和水平的二维地震动输入的振动台试验,通过对试验得到的结构在二维地震动作用下的加速度、应变、内力响应的分析,为评价国家体育馆屋盖结构在二维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,同时结果表明双向张弦结构具有良好的抗震性能,是一种具有良好应用前景的新型大跨度结构体系。
【Abstract】 The earthquake table test of the roof model of National Gymnasium is the first time to do the test of so large size of the structure at home and abroad.The vertical and horizontal vibration table tests of the roof model are conducted.The responses of acceleration,displacement and stress of the structure under the two-dimensional earthquake provide the tested data for evaluating the seismic performance of the roof and can be referencd in seismic analysis of similar structure.At the same time,the results indicate that bi-directional beam sting structure have good aseismic capability and is a new-style great structure,which has favorable application in future.
【Key words】 roof model of National Gymnasium bi-directional beam string structure; vibration table test; two-dimensional earthquake; dynamic performance;
