（中国建筑设计研究院，北京 100044）[摘要] 混凝土与木混合结构将混凝土框架与轻型木楼盖结合在一起，适合在多层结构中应用。为了研究混合结构中轻型木楼盖与混凝土框架在水平力作用下的协同工作性能，对于一个一层的混凝土框架木楼盖混合结构模型进行了水平单向弹性加载试验和往复加载破坏试验。结果表明：当混合结构在弹性受力范围内，木楼盖体现出了良好的平面内刚度，能够协调各榀混凝土框架柱顶位移、分配各柱水平力；当混合结构达到塑性时，木楼盖具有较高的水平承载力，保证结构整体的延性、耗能能力以及极限承载能力。[关键词]混合结构;混凝土框架;木楼盖;单向加载;往复加载中图分类号：TU398 文献标识码：A 文章编号：1002-848X(2013)S1-0731-05Test of one storey hybrid structure with concrete frame and timber floor under lateral loadLi Shuo（China Architecture Design & Research Group, Beijing 100044, China)Abstract: Concrete-timber hybrid structure is composed by concrete frame and wood diaphragm, which could be used in multi-storey residential buildings. In order to get a better understanding of the performance of hybrid structure under horizontal load, a one storey structural model which constructed by concrete frame and timber diaphragm, was tested under monotonic horizontal load and cyclic horizontal load. Results showed that: in the elastic range, wood diaphragm maintained high in-plane rigidity which made it possible to distribute the lateral force in concrete columns. In the plastic stage of the structure, the wood diaphragm had high in-plane bearing capacity which guaranteed the whole structure with good ductility, energy consumption ability and ultimate bearing capacity.Keywords: hybrid structure; concrete frame; wood diaphragm; monotonic load; cyclic load
