摘　　要：为研究劲性装配式框架核心筒体结构整体抗震性能,进行1∶3的缩尺模型振动台试验,获得结构体系在地震作用下整体抗震性能与结构破坏模式,并考证叠合梁与钢管混凝土柱、叠合梁与抗震墙、楼板等连接节点在地震作用下的可靠性。结果表明,该结构体系具有较高的承载力及良好的整体抗震性能,节点连接形式总体能满足现行规范抗震设防要求。A 1/3 scale model was constructed and subjected to a series of earthquake excitations to investigate the seismic behaviors of precast frame-core tube structures with reinforced concrete （RC） beams and concrete filled steel tubular （CFST） conlums. The seismic behaviors of this type of structures, including the seismic responses, the reliability of connections, and the failure mechanisms were studied. The test results show that ： this type of structures has excellent bearing capacity and seismic behavior, and the connections could generally satisfy the requirement in the structural design codes.
