摘　　要：为改善混凝土装配结构的抗震性能,提出了混凝土挂柱挂板组合墙装配框架结构体系,并通过设计1/2缩尺模型对混凝土挂柱挂板组合墙装配框架结构的抗震性能进行了振动台试验研究,通过白噪声扫描和输入地震波强度逐步增加的加载试验方法,研究了整体结构的动力特性变化规律、整体结构的动力响应规律、局部组合墙体与主体结构相互作用以及退化规律。研究结果表明:挂柱挂板组合墙与主体结构的连接以及挂板挂柱之间具有较好的连接性能,能保证整体结构的抗震性能;挂柱挂板组合墙对整体结构的刚度贡献随着地震强度的增加先增加后减小;整体结构首先在挂板挂柱出现裂缝,随后挂柱挂耳两端逐步损伤压碎,最后主体结构逐渐屈服,表现出良好的整体连接性能和抗震性能。In order to improve the seismic performance of precast concrete structures, frame precast structure con- taining concrete hanging column and hanging slab composite wall was proposed in this paper, and shaking table tests on 1/2 scale model of the proposed frame structure were performed to study the seismic performance. Through the test method of noise scanning and seismic wave intensity increasing gradually, the dynamic characteristics of the whole structure, the dynamic response characteristics of the overall structure, and the interaction and degradation of local wall and the main structure were analyzed. The research results indicate that the connection between hanging- column-hanging-slab composite wall and the frame structure works well, as well as the connection between hanging slab and hanging column, which ensure the seismic performance of the whole structures. The stiffness contribution of the composite wall on the whole structure increased firstly and then decreased with the increase of the earthquake strength. In the whole precast, the hanging slab and column cracks firstly, then the hanger on the hanging column crushed progressively on their both ends, and the structure yield gradually after that, the whole structures showed good connection and seismic performance.
