为研究钢筋混凝土空心桥墩的抗震性能，采用开源有限元软件OpenSees进行了建模和非线性动力分析，分析了不同轴压比、配筋率和高度的桥墩的抗震性能，分析结果表明此类钢筋混凝土空心桥墩抗震性能良好，各特性参数对其抗震性能均产生不同程度的影响，研究结果对于桥梁抗震设计具有一定参考价值。

英文摘要：

In order to study the earthquake resistance of hollow pier, models with different axial compression ratio, reinforcement ratio and heights were built, and nonlinear dynamic time-history analysis was carried out through the finite element analysis software OpenSees. The results indicate that the seismic performance of these hollow piers is impressive, and that the specimen properties affect the performance more or less. The findings of this paper can be used in bridge engineering.
