摘　　要：根据钢筋混凝土柱-钢梁(RCS)组合节点的破坏模式,分析了节点的受力机理。RCS组合节点的传力机构大致分为四种:钢梁腹板框架-剪力墙机构、内部混凝土斜压机构、外部混凝土斜压机构及桁架机构,同时分析各传力机构能够承担的抗剪承载力贡献值。根据国内外研究资料,考虑节点区混凝土受力机理不同,重点介绍了RCS组合节点抗剪承载力公式的研究进展,为后续RCS组合节点抗剪承载力研究提供参考。Based on the failure modes of reinforced concrete column-steel beam（ RCS） composite joints, the force mechanism of the joint was analyzed. Force transferring mechanisms of RCS composite joints are divided into four categories,including steel beam web prame-shear wall mechanism,internal concrete inclined compression mechanism,external concrete inclined compression mechanism and truss mechanism. The contribution of each force transferring mechanism to the shear capacity was analyzed. According to the domestic and foreign research data, taking into consideration of different force mechanisms of concrete in node regions,the research progress of shear bearing capacity formula of RCS composite joints was focused on,providing reference for subsequent study on shear bearing capacity of RCS composite joints.
