摘　　要：钢框架钢筋混凝土筒体结构在高烈度区的抗震性能和地震剪力在钢框架和混凝土筒体之间的分配比例是这种体系抗震性能研究的重点。模型的振动台试验表明,该结构体系的破坏集中于混凝土筒体,钢框架没有出现明显的破坏现象,结构整体的延性较好;而混凝土筒体结构承担了绝大部分的地震剪力。建议在混凝土筒体内预埋尺寸较小的构造用钢柱、钢梁,以改善筒体延性。The seismic performance of steel frame-concrete core wall structure in high seismic area and the distribution ration of earthquake force between the steel frame and concrete core wall structure are the two important problems in the steel frame-concrete core wall structure system research. The shaking table test of a model shows that the damage mainly concentrates in the concrete core wall structure and there are no obvious damage in the steel frame. The ductility of the whole structure is good and the earthquake force is mainly carried by the concrete core wail structure. Some simple steel columns and beams are suggested to be constructed in the concrete wall to improve its ductility.
