摘要: 对比国内外三部混凝土规范中计算框架梁柱节点受剪承载力的公式，通过已有的40个节点试验结果的对比，分析各规范公式的优缺点、安全性以及适用性。结果表明：对于矩形柱节点，GB50010《混凝土结构设计规范》对边节点受剪承载力的估计偏大，对中节点受剪承载力计算值与试验值较为吻合；ACI318M《美国房屋建筑混凝土结构规范》对边节点和中节点的计算方法偏安全，安全储备较高；AIJ《钢骨钢筋混凝土结构计算标准及解说》对边节点和中节点的计算方法偏不安全。
Abstract: Shearing capacity formulas of RC Joint from codes of different countries are compared. The ad-vantages and disadvantages, safety of different formulas and the applicability of the various for-mulas are analyzed by comparing 20 experimental results of joints existed. The results show that according to rectangular column, GB50010-2010 calculation is larger for exterior joint shear, but close to interior joint shear. ACI318M calculation is safe for both, but with higher safety reserve. AIJ calculation tends to be unsafe for both.
