利用ANSYS模拟桥墩滞回性能的建模方法

Modeling Methods on Simulation of Hysteretic Behavior of Bridge Piers Based on ANSYS Software

基于钢筋混凝土桥墩低周反复荷载试验结果,利用ANSYS有限元分析软件,建立了桥墩的有限元计算模型,并对其进行了低周反复荷载试验下全过程的非线性有限元分析,得到了桥墩的滞回曲线、骨架曲线以及桥墩在不同受力阶段的破坏形态。将计算结果与试验结果进行对比,发现计算得到的桥墩滞回曲线和骨架曲线与试验结果吻合较好,对于桥墩破坏形态的模拟,也取得了比较理想的结果。

Based on the low-cycle reversed loading tests, three RC bridge piers were modeled with ANSYS software and the low-cycle reversed loading tests were non-linearly simulated. The hysteretic curves, skeleton curves, and the failure mode of the bridge piers in different experiment stages were obtained. The calculated hysteretic curves and skeleton curves were corresponding well with experimental results, the failure mode obtained by analysis were also agreed well with experimental results.
