摘要
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。
A controllable rocking reinforced concrete frame（ CR-RCF） with column-end-hinge Joints is a new type seismic-reducing structural system with special design for column-beam joints and the application of structural control theory and technology. Based on the comparative shaking table tests for a 1 /3 scale 3-story-3-span CR-RCF with columnend-hinge Joints and a conventional reinforced concrete frame with the same sizes, the dynamic characteristics,acceleration reponses and displacement responses of the model structures under different earthquake levels were studied to validate the aseismic performance of CR-RCF with column-end-hinge Joints. Test results indicated that the CR-RCF with column-end-hinge Joints has a definite centralized energy dissipation mechanism,and an excellent self-centering capability during earthquake; it is a damage-free structural system with the main component keeping intact under major earthquake.
