摘要:
地震荷载作用下钢筋混凝土桥墩易发生严重破坏,模拟桥墩在循环荷载作用下的非线性滞回反应是桥梁抗震研究的重要内容.以8个发生弯曲破坏的钢筋混凝土桥墩抗震拟静力试验结果为依据,基于OpenSees中的非线性梁柱单元、零长度转动弹簧单元和零长度剪切弹簧单元,建立了考虑弯曲、粘结滑移和剪切变形的桥墩抗震数值分析模型.将模拟得到的试件滞回曲线,墩顶弯曲、粘结滑移和剪切变形等成分、初始刚度和残余位移与试验结果进行了对比.结果表明,所建模型对各桥墩的滞回曲线、各变形成分、初始刚度和残余位移有较好的模拟效果.
Abstract:
Reinforced concrete (RC) bridge piers are vulnerable to seismic effects and simulation of the hysteretic behavior of RC bridge piers is an important issue for seismic design of bridges. Based on 8 seismic quasi-static test results of RC bridge piers failed in flexural mode, the hysteretic analysis model for RC bridge piers was built by OpenSees program. The nonlinear beam-column element, zero-length rotational spring element and zero-length shear spring element were used to model flexural, bond-slip and shear deformation, respectively. The simulated hysteretic curves, flexural, bond-slip, shear deformations, initial stiffness and residual displacement of the pier were compared with test results. It is found that the simulated hysteretic curves, each deformation component, initial stiffness and residual displacement of the pier agree well with test results.
