中文摘要：

受控摇摆式钢筋混凝土框架结构（controllable rocking reinforced concrete frame,简称CRRCF）是一种新型减震耗能结构。通过对摇摆节点及整体框架进行的低周反复加载试验,研究其滞回特性。根据整体摇摆框架的滞回曲线得到了受控摇摆式钢筋混凝土框架的等效黏滞阻尼比。通过摇摆节点试验及理论分析,提出了摇摆节点的恢复力模型。利用有限元软件ABAQUS对受控摇摆式钢筋混凝土框架结构进行数值模拟,得到了不同节点刚度水平下结构的地震动力响应,并分析得出摇摆节点刚度的合理弱化程度。通过受控摇摆式钢筋混凝土框架和常规钢筋混凝土框架（RCF）的动力响应对比,可以发现CR-RCF结构可以有效降低结构的层间剪力与加速度响应。与RCF结构相比,CR-RCF结构的剪力与位移响应沿楼层分布较为均匀,这有利于防止层间变形过于集中,使各层材料都能得到充分利用。在受控摇摆式钢筋混凝土框架结构中设置耗能阻尼器,进行时程分析可以发现结构的位移响应可以得到有效的控制。

英文摘要：

The controllable rocking reinforced concrete frame （CR-RCF） structure is a new type of earthquake-re- sisting structure with energy-dissipation. Through the reversed cyclic loading test, the hysteretic behavior of the rocking frame and rocking joint was studied. According to the hysteresis curve of the CR-RCF, the equivalent vis- cous damping ratio was calculated. By reversed cyclic test and theoretical analysis of the rocking joints, this paper proposes the restoring force model of the rocking node. By using finite element analysis software ABAQUS, dynamic characteristics of the CR-RCF structure are obtained and the joints are weakened in different levels, and the reason- able degree of rocking joints stiffness weakening is analyzed. By comparing the dynamic response of conventional reinforced concrete frame with the CR-RCF structure, it can be found that the CR-RCF structure can effectively re- duce the structural shear and acceleration response. Compared with the RCF, shear and displacement responses of the CR-RCF are more evenly distributed among the floors, which is helpful in preventing excessive concentration of interlayer deformation, so that every layer＇ s components can be fully utilized. After installing metal dampers is the structure, the displacement response of the CR-RCF can be effectively controlled.
