| 摘 要： | 在地震荷载作用下,钢筋混凝土桥墩是最易破坏的桥梁构件,如何较可靠地模拟钢筋混凝土桥墩在循环荷载作用下的非线性滞回反应是桥梁结构抗震研究的重要内容。以呈弯曲破坏形态的钢筋混凝土桥墩的拟静力试验结果为依据,基于OpenSees中的Beamwith Hinges Element单元,分别建立了圆形墩和矩形墩的滞回分析纤维单元模型。由计算结果与试验结果对比可知,所建立的纤维单元模型对桥墩的骨架曲线及滞回曲线都有良好的模拟效果,且能体现桥墩在反复加载过程中刚度、强度退化现象。

| Abstract: | Reinforced concrete bridge pier is the most easily destroyed bridge member under seismic loading,how to reliably simulate nonlinear hysteretic response of reinforced concrete bridge pier under cyclic loading is an important content in seismic resistance of bridge structure research field.Based on the pseudo-static test of RC bridge piers which have flexural failures,the BeamwithHingesElement in OpenSees program was used to model the hysteretic behaviors of circular sectional and rectangular sectional bridge... |
