| 摘 要： | 以4个呈弯曲破坏形态的圆形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,建立了相应的桥墩滞回分析纤维单元模型。由模拟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,表明了模型的有效性。

| Abstract: | Based on the pseudo-static test of 4 R/C bridge columns,which are circular-section and flexural failure,the BeamwithHingesElement in OpenSees is applied to model the hysteretic behavior of R/C bridge columns subjected to cyclic loading.The comparison between computed results and experiment results shows that the fiber element model in OpenSees can accurately stimulate the skeleton curves,hysteretic curves of the columns,and also describe their stiffness,strength degradation in the cyclic loading process. |
