摘要以普查地区典型的住宅楼建筑为试验体原型，在轴压比一致相似的前提下，开展几何相似比为1/8的高层剪力墙振动台试验研究。通过对模型输入不同地震动，分析结构的加速度、位移等动力响应，研究了剪力墙结构体系损伤破坏路径、剪力墙及连梁构件的破坏特点。根据试验现象和试验结果分析，研究结构体系的频率衰减、刚度退化、层间位移角等地震响应特性变化规律。研究结果表明：原结构与模型的折算后周期最大误差为5.4%，结构在经历7、8度罕遇地震后结构频率降低17.43%，刚度退化严重，长墙出现斜向裂缝，短墙出现水平弯曲裂缝，结构的各层加速度放大系数降低。对于规则结构可以按照单向输入地震动进行结构弹性设计，顶层的加速度放大系数为2.6-3，顶层结构的层间剪力较大，设计中不可忽略。试验表明长墙可作为整体结构体系第一道抗震防线，可有效的耗散地震能量，层间位移角可满足高层混凝土技术规程的限值要求，21世纪初建立的短肢剪力墙结构可以很好的实现抗震三水准要求，不需要进行加固与改造。

Abstract：Taking a typical residential building in the survey area as the prototype, the shaking table test of high-rise shear wall with geometric similarity ratio of 1/8 was carried out under the premise of uniform and similar axial compression ratio. By inputting different ground motions into the model, the dynamic response of the structure, such as acceleration and displacement, are analyzed, and the failure path of the shear wall structure system, the failure characteristics of the shear wall and the connecting beam members are studied. Based on the analysis of the experimental phenomena and results, the seismic response characteristics of the structural system, such as frequency attenuation, stiffness degradation and inter-storey displacement angle, are obtained. The results show that the maximum period error between the original structure and the model is 5.4%. The structural frequency decreases by 17.43% after the rare earthquake of 7 and 8 degrees, meanwhile, the stiffness degrades seriously, the long wall appears oblique crack, then the short wall appears horizontal bending crack, and the acceleration amplification coefficient of each layer of the structure decreases. For regular structure, structural elastic design can be carried out according to unidirectional input ground motion. The acceleration amplification coefficient of the top floor is 2.6-3, and the shear force of the top floor structure is large, which can not be ignored in the design. The test results show that the long wall can be used as the first seismic defense line of the whole structure system, which can effectively dissipate seismic energy, and the displacement angle between floors can meet the limit requirements of the technical regulations of high-rise concrete. The short-leg shear wall structure established in the early 21st century can well meet the seismic three-level requirements, and there is no need for reinforcement and reconstruction.
