【摘要】 对一个大比例低配筋圆端型桥墩模型进行了拟动力试验研究,获得了该桥墩在实际地震波作用下的地震反应及破坏形式,对该桥墩的抗震性能进行了分析,得到了该桥墩能够承受的实际地震动水平,对其抗震能力进行了评估;同时得到了其滞回曲线,为低配筋桥墩的抗震设计、评估与加固提供了依据。更多还原

【Abstract】 A large scale round-ended pier model with low ratio of reinforcement is made,and the seismic performance of pier model is studied by pseudo dynamic test.The seismic responds and hysteretic curve of pier acted by real earthquake wave are gained.The seismic performance of pier model is analyzed and the enduring actual level of earthquake is given.更多还原
