柱端铰型受控摇摆式钢筋混凝土框架抗震性能的振动台试验研究

柱端铰型受控摇摆式钢筋混凝土框架结构，是经过特殊节点设计与结构控制理论相结合而形成的一种新型消能减震结构体系。通过对一个缩尺比1/3的三层三跨摇摆框架模型和一个同尺寸的常规钢筋混凝土模型进行模拟地震振动台对比试验，研究模型结构在不同水准地震作用下的动力特性、加速度响应、位移响应，分析结构的抗震性能。试验结果表明柱端铰型受控摇摆式钢筋混凝土框架集中耗能机制明确,地震作用后能自主复位，主体承重构件在大震下保持完好，是一种免损伤的新型结构体系。

Shaking Table Test Study on the Seismic Performance of a Controllable Rocking Reinforced Concrete Frame with Column-end-hinge Joints

The controllable rocking reinforced concrete frame (CR-RCF) with column-end-hinge Joints is a new type seismic-reducing structural system with special design for the column-beam joints and the application of structural control theory and technology. Based on the comparative shaking table tests of a 1/3 scale 3-story-3-span CR-RCF with column-end-hinge Joints and a same size conventional reinforced concrete frame, the dynamic characteristics, acceleration reponse and displacement response of the model structures under different earthquake levels are discussed to validate the seismic performance of CR-RCF with column-end-hinge Joints. Test results indicate that the CR-RCF with column-end-hinge Joints has a definite centralized energy dissipation mechanism, excellent self-centering capability during earthquake and it is a damage-free structural system with the main bearing component remaining intact under major earthquake.
