型钢混凝土剪力墙恢复力模型研究
|
摘要
通过8个型钢混凝土剪力墙的低周反复加载试验,重点研究轴压比、配钢率、配箍特征值对剪力墙滞回性能的影响。根据试验结果,通过理论分析,提出了以开裂点、屈服点、峰值点和极限点为特征点并考虑刚度退化的四线型荷载-位移恢复力模型,给出了各特征点参数以及各阶段刚度计算公式。分析结果表明,用该文恢复力模型所得计算滞回曲线与试验滞回曲线符合较好。该文的恢复力模型既反映了主要因素的影响,又便于进行结构非线性动力分析,可供型钢混凝土剪力墙非线性地震反应分析和工程设计应用。
To study the seismic behavior of shear walls,eight steel reinforced concrete(SRC) shear walls were tested under reversed cyclic lateral loads with varied axial load ratio,steel ratio and stirrup characteristic value.Their effects on the hysteretic characteristics were investigated.Based on the experimental results,the restoring force model of SRC shear walls is established.A four-linear skeleton curve model including stiffness degradation was proposed,which was defined through cracking point,yield point,peak point and ultimate point.The formula to calculate these points are recommended through theoretical analysis.The results show that the calculated restoring model agrees well with the experimental result,which can be conveniently applied to nonlinear dynamic analysis of SRC shear wall buildings.
