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 the actual project, the method of using steel bars to replace the beam-column joints of the steel core through the core area of the joint was proposed by means of the scaling model test of two steel-concrete composite beams and the connection of reinforced concrete columns. Experiments show that such nodes are reasonable in structure, reliable in force and convenient in construction, and have good bearing capacity and seismic performance. Based on the experimental study, the shear capacity and the construction measures of the joints are put forward to provide reference for the design and construction of such joints.
