| 摘 要： | 运用大型有限元软件ABAQUS对局部钢管约束钢筋混凝土桥墩的有限元计算模型进行低周反复荷载作用下全过程的非线性有限元分析,通过分析滞回曲线、骨架曲线及等效刚度退化曲线的特点发现,局部钢管约束钢筋混凝土高桥墩具有很好的延性性能,可以作为桥墩延性抗震设计的一种备选方案。

| Abstract: | RC bridge pier packaged with steel tube partially were simulated with ABAQUS software under low cyclic loading. Based on study of the hysteretic, skeleton and the stiffness degradation curves of the bridge piers, it is discovered that the reinforced concrete piers packaged with steel tube partially has a better ductility, and can provide an possible option for ductile seismic design of bridge pier. |
