本文指出内柱板柱节点的破坏形态和危险截面随节点所传递的不平衡弯矩和剪力之比而变化,分析了影响极限水平剪应力的主要因素,提出了一种新的强度分析方法,并用ACI318-77的方法Y.Kanoh的方法及建议的方法对77个节点试件的试验结果进行了验算对比,结果表明,建议的方法比现有的方法更符合试验结果。

This paper points out that the failure modes and the dangerous sections of inner column-column joints vary with the ratio of the unbalanced bending moment and the shear force transmitted by the joints. The main factors affecting the ultimate horizontal shear stress are analyzed, and a new strength analysis method is proposed. The method of Y. Kanoh and the proposed method of ACI 318-77 were used to compare and verify the test results of 77 node specimens. The results show that the proposed method is more consistent with the experimental results than the existing methods.
