| 摘 要： | 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,建立桥墩的有限元计算模型,并对其进行承载力验证及低周反复荷载试验下全过程的非线性有限元分析,与相应试验结论吻合较好.通过施加温度场模拟钢筋锈胀力对混凝土桥墩的作用,进一步研究钢筋锈蚀后桥墩在不同锈蚀率下滞回曲线、骨架曲线以及桥墩耗能能力.分析比较表明:用温度场模拟钢筋锈胀力对混凝土桥墩的作用可以取得令人满意的结果.本方法可供锈蚀桥墩的抗震性能研究参考.

| Abstract: | Based on the low-cycle reversed loading tests,reinforce bridge piers were modeled with ANSYS software and the low-cycle reversed loading tests were non-linearly simulated.The calculated hysteretic curves of the finite element mode by analysis were also agreed well with experimental results.The corrosion effect of steel bar to bridge pier were simulated by temperature field.The hysteretic curves,skeleton curves,and energy dissipation capacity of the bridge piers in different corrossion rate were obtained.It ... |
