摘　　要：为研究带有装配式楼板的新型混合结构体系的抗震性能,设计一个三层两跨缩尺比例为1/4的结构模型,通过不同地震水平的等效单自由度拟动力试验,对模型的耗能能力、刚度退化情况、变形性能等进行分析。结果表明,板底附加X形水平方向斜撑的不加后浇面层楼板的刚性可以保证结构的空间整体性和水平力的有效传递,该结构体系具有良好的抗震性能,因此在高烈度地区可以考虑用不加后浇面层的装配整体式楼板代替现浇楼板。研究结果为该类结构体系的抗震设计提供可靠的理论依据。Seismic behavior of new hybrid structural system with prefabricated floors was studied. A model of three layers two across structure with the scale ratio of 1/4 was designed. Energy dissipation capacity, stiffness degradation, deformation performance and so on of the model were analyzed through equivalent single degree of freedom pseudo-dynamic test under different earthquake levels. The results show that additional X bracing at the bottom of the rigidity of the floor without surface layer can ensure the integrity of the structure and the effective transmission of the horizontal force. The structure system has a good seismic performance. It was proved that the prefabricated floor without surface layer can take the place of east-in-place floor in areas with high seismic intensity. The research results provide a reliable theoretical basis for the seismic design of this kind of structural system.
