（中國建筑設(shè)計研究院，北京 100044）[摘要] 混凝土與木混合結(jié)構(gòu)將混凝土框架與輕型木樓蓋結(jié)合在一起，適合在多層結(jié)構(gòu)中應(yīng)用。為了研究混合結(jié)構(gòu)中輕型木樓蓋與混凝土框架在水平力作用下的協(xié)同工作性能，對于一個一層的混凝土框架木樓蓋混合結(jié)構(gòu)模型進(jìn)行了水平單向彈性加載試驗和往復(fù)加載破壞試驗。結(jié)果表明：當(dāng)混合結(jié)構(gòu)在彈性受力范圍內(nèi)，木樓蓋體現(xiàn)出了良好的平面內(nèi)剛度，能夠協(xié)調(diào)各榀混凝土框架柱頂位移、分配各柱水平力；當(dāng)混合結(jié)構(gòu)達(dá)到塑性時，木樓蓋具有較高的水平承載力，保證結(jié)構(gòu)整體的延性、耗能能力以及極限承載能力。[關(guān)鍵詞]混合結(jié)構(gòu);混凝土框架;木樓蓋;單向加載;往復(fù)加載中圖分類號：TU398 文獻(xiàn)標(biāo)識碼：A 文章編號：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
