摘　　要：通过5根不同开孔尺寸和不同补强方式的框架梁端开圆孔的钢筋混凝土梁的试验,研究了梁端开孔梁的破坏特点,根据试验结果,参照我国现行规范,对目前国内部分学者提出的框架梁端开圆孔的钢筋混凝土梁孔处受剪破坏的承载力计算公式进行了分析探讨.The experimental testing of five reinforced concrete frame beams with different end circular opening size and reinforced method are carried out, and the failure characteristics of the reinforced concrete frame beam with end opening is studied. According to the results of the experimental testing, and refering to the China current specifications, the beating capacity calculation of shear failure at circular opening in the end of the reinforced concrete frame beam presented by other scholars is analyzed and discussed.
