木-混凝土组合梁剪力连接件的研究现状

木-混凝土组合梁是利用各种不同的剪力连接件把木和混凝土这两种材料结合而成的一种新型整体受力构件。木梁与混凝土板的交界面上存在着纵向剪力,由混凝土与木梁之间的抗剪连接件承受。文章总结了国内外木—混凝土组合结构的相关研究内容,详细地介绍了国外木—混凝土组合梁剪力连接件的研究现状,并提出现阶段我国在木结构相关领域的研究方向。

Review on Shear Connectors in Wood-concrete Composite Beams

In wood–concrete composite beams,a wood beam is connected to a concrete slab.The approach is to pour fresh concrete over the wood.Mechanical linkage between concrete and wood is provided through various sorts of shear connectors which bear the longitudinal shear force between wood beam and concrete slab.This paper reviewed worldwide research on the performance of shear connectors in wood–concrete composite structures.The current status of research on connectors used in wood–concrete composite structures was summarized and the future trend was also discussed.It is believed that this study would provide some insight and suggestions for a further research program on shear connectors in China.
