摘要:
为了建立钢筋混凝土箱型墩在双向地震作用下弹塑性响应的简化分析模型,对其在双向反复荷载作用下的荷载-位移恢复力特性进行了研究.首先介绍了钢筋混凝土箱型墩双向拟静力试验的基本情况及其破坏模式.其次,结合双向压弯作用下钢筋混凝土箱型截面的弯矩曲率分析,建立了箱型墩构件峰值位移、极限位移和残余变形的计算方法,并提出了钢筋混凝土箱型墩荷载-位移三折线骨架曲线和卸载刚度的计算公式,建立了相应的理论恢复力模型.最后,利用试验结果,对理论恢复力模型进行分析和验证.结果表明,钢筋混凝土箱型墩在双向荷载作用下以弯曲破坏为主,实测和计算骨架曲线、滞回曲线吻合良好,考虑双向荷载作用的理论恢复力模型能够反映钢筋混凝土箱型墩的基本抗震性能.
Abstract:
To establish the simplified analysis model for elastoplastic seismic response of reinforced concrete box piers subjected to bidirectional seismic excitation, the load-displacement restoring force characteristics subjected to the bidirectional cyclic load were analyzed. First, the basic situation and the failure mode of the biaxial quasi-static test were introduced. Secondly, the calculation methods for the peak displacement, the ultimate displacement, and the residual deformation of the box pier were established combined moment curvature relationship analysis of the box section under the biaxial compression and bending load. The calculating formulas of the three-segment-line load-displacement skeleton curve and the unloading stiffness were further presented, and the corresponding theoretical bidirectional restoring force models were developed. Finally, the theoretical bidirectional restoring force models were analyzed and verified by testing results. The results show that the bending failure is the main failure mode of the reinforced concrete box pier under the bidirectional cyclic load. The theoretical load displacement skeleton curve and the hysteresis curve agree well with the test ones, and the theoretical restoring force model considering the bidirectional cyclic load can reveal the basic anti-seismic performance of reinforce concrete box piers.
