简要介绍了美国、日本、新西兰和中国相关规范关于钢筋混凝土梁柱节点受剪承载力的计算方法，并基于已有的试验研究数据进行比较分析。计算结果表明：①美国 ACI 规范未考虑轴压力和正交梁空间约束效应对节点受剪承载力的有利影响，对中节点、边节点和空间节点受剪承载力估计偏于保守，安全储备最高。②日本 AIJ 规范对中节点、边节点和空间节点受剪承载力估计均过大，偏于不安全。③新西兰 NZS 规范设计方法考虑了空间节点的约束效应，但计算结果整体偏保守，其中对空间节点的受剪承载力估算最为保守。④中国规范对中节点、边节点和空间节点受剪承载力计算值与试验值整体吻合较好，但相比美国 ACI 规范和新西兰 NZS 规范，安全储备偏低。

Four methods to calculate the shear strength of RC joints prescribed by ACI318-05, AIJ, NZS3101, GB5001-2010 were introduced. The results indicate that the ACI specification dose not consider the positive factors of the axial force and orthogonal beam space constraint, and the shear strength calculation is relatively conservative, which leads to high safety reserve; that the AIJ calcu-lation for all kinds of joint shear is larger, which tends to be unsafe; that the NZS considers the effect of restraint space node, but it provides a conservative calculated results, especially for the space joint; that the numerical results given by GB5001-2010 are in good agreement with the exper-imental results for different joint types with lower safety margin than the ACI and NZS.
