摘　　要：在分析归纳近年来国内外抗震框架节点试验研究结果的基础上，首次明确提出将在梁端或柱端纵筋屈服后可能发生剪切失效或破坏的节点的受力特征分为斜拉型、斜压型和斜拉—斜压复合型三类，并给出了这三类受力特征的节点在相对作用剪力和相对配箍率坐标中出现的区域，还对其受力性能随相对作用剪力或（和）相对配箍率变化的规律及原因进行了分析。On the basis of analysis and induction of experimental results on earthquake-resistant frame joint both at home and abroad, it is clearly pointed out that the mechanical characteristics of the joint in which shear failure may occur after yielding of longitudinal rebars at the beam end or at the column end are classified into three types, i. e ., diagonal tension, diagonal compression and a combination of diagonal tension and diagonal compression. A region of these three types of mechanical characteristics in the coordinates composed of relative shear force and relative ratio of transverse reinforcement is given, and the variation law and the corresponding reasons for the mechanical behaviors with the relative transverse reinforcement are analysed.
