摘要
设计了10层的框架结构模型,进行了单向及双向作用时不同频谱地震波输入下的振动台试验,对试验结果进行了对比分析,揭示了结构的动力特性及地震反应之间的联系。结果显示:加速度、层间位移和应变在地震波作用下的变化趋势是一致的,结构的层间位移和加速度沿层高的分布不一样;双向作用下结构的反应并不一定比单向作用时的反应大。并依据试验过程当中的测试数据,进行了相应的数值模拟,与实测结果进行了对比,吻合较好,可以为后续类似的研究工作提供借鉴。
This paper designed a ten-story frame structure model and carried out shaking table test under different spectrum seismic wave input when unidirectional and bidirectional action. The results of the test are compared and analyzed. Relationship between structural dynamic characteristics and seismic response is revealed. The results show that the trend of acceleration, inter story drift and strain under action of seismic waves is consistent. The inter story drift and acceleration distribution along the height of the structure are different. And reaction of the structure under bidirectional action is not necessarily greater than that of one way reaction. According to the test data, the corresponding numerical simulation is carried out. It is in good agreement with the measured results. This can be used as a reference for similar research work in the future.
