钢筋混凝土柱-钢梁（ RCS）组合节点受力复杂，不同的节点构造措施对其破坏模式和承载力影响显著。根据试验和数值模拟结果，分析了8种RCS节点构造措施的传力机理及其对节点承载力的贡献，并提出设计建议。分析了已有节点破坏模式的特征、受力机理、影响因素等；并根据国内外试验，提出了两种新的破坏模式：部分剪切破坏和节点-梁混合破坏。通过分析其破坏特征、发生条件、受力机理等，给出了承载力计算建议。研究成果为进一步建立RCS组合节点的受剪承载力公式提供依据。

The joint of the composite frame system consisting of reinforced concrete column and steel beam ( RCS) is a complex part .The different detailing requirements and failure modes have great effects on the RCS composite joint behaviors .Based on great amount of experimental research and numerical simulations , the in-fluence of eight parameters on the force transfer mechanism and shear capacity were analyzed .Some sugges-tions were presented for design .Two failure modes in RCS joints were introduced and suggestions were also presented for the joint design .In addition, two new failure modes, partial panel shear and beam & panel shear , were proposed .Failure characteristic , failure condition , factor and force mechanism for these two modes were described in detail .Some proposals were presented for joint shear capacity calculation .This paper provides a basis for distinguishing the shear failure modes .The shear capacity formula of RCS joints were pro-vided.
