钢-混凝土组合梁与钢筋混凝土柱连接节点的试验研究

Experimental research on joint between steel-concrete composite beam and reinforced concrete column

依托实际工程,通过两个钢-混凝土组合梁与钢筋混凝土柱连接节点的缩尺模型试验,提出了以对拉钢筋代替钢梁翼缘穿过节点核心区的梁柱节点做法。试验证明,此类节点构造合理,传力可靠,施工方便,具有良好的承载能力和抗震性能。在试验研究基础上,提出了节点的抗剪承载力及构造措施,为该类节点的设计与施工提供参考。

Based on a real case,design concept and constructional details of the joints between steel-concrete composite beam and reinforced concrete column were introduced through the experiment of two models,in which steel beam flanges were substituted with reinforcement in the case design of a conference building.The test results indicate that the joint is comparatively safe and rational.Shear capacity and construction methods are also advanced which provide reference for the project design and construction.
