| 摘 要： | 为了研究钢管混凝土梁柱节点受剪承载力,对钢管混凝土梁柱节点的剪切破坏机理进行了深入的讨论,分别对核心区混凝土、钢管以及加强环对节点的抗剪贡献进行了分析,提出了考虑轴压力、柱端弯矩、梁端竖向剪力等因素的梁柱节点受剪承载力计算模型,通过实例验证了公式的合理性。

| Abstract: | In order to study the shear bearing capacity of concrete-filled steel tube beam-column joints, shear failure mechanism of concrete-filled steel tube beam-column joints was discussed. The shear contribution of core concrete, steel tube and reinforcement ring to joint was analyzed. Calculation model on shear bearing capacity of concrete-filled steel tube beam-column joints considering axial load ratio, bending moment of column, and vertical shear of beam is proposed, and the rationality of the formula is verified by an example. |

| Keywords: | steel tube concrete beam column joint shear bearing capacity computation model |
