摘要: 为研究钢筋混凝土柱墩的抗震性能，进行了箱型截面混凝土柱墩水平双向往复拟静力试验，利用ABAQUS有限元分析软件在PQ-Fiber子程序的基础上进行了pushover数值模拟，模拟结果与实验基本吻合。在实验基础上截断部分钢筋进行双塑性铰的模型分析，表明可以在墩底形成双塑性铰，通过对比单双塑性铰柱墩的骨架曲线、滞回曲线、应变曲线等，表明双塑性铰柱墩承载力没有明显变化，而极限变形能力明显提高，桥墩的抗震能力得到增强。
Abstract: In order to study the seismic performance of reinforced concrete column piers, the horizontal two-way reciprocating pseudo-static test of box-section concrete column piers was carried out. The finite element analysis software of ABAQUS was used to simulate the pushover performance based on the PQ-Fiber subroutine. The simulation results were basically consistent with the experiment results. Partial reinforcement is cut off on the basis of the experiment, and the model analysis of the double plastic hinges is carried out, which shows that the double plastic hinges can be formed on the column pier. The skeleton curves, hysteresis curves and strain curves of the single and double plastic hinges piers are compared. It shows that the double plastic hinges improve the ultimate deformation capacity of the pier, and the seismic capacity of the pier is enhanced.
