摘　　要：通过对 6组共 1 2个预留洞口的钢筋混凝土框架结构迭合主次梁节点的破坏试验 ,研究了不同预留洞口高度和不同配筋形式对节点抗剪性能的影响 ;分析了节点次梁端部的破坏机理 ,并在此基础上提出了次梁节点抗剪强度计算公式。A failure test is carried out on the primary and secondary beam nodes totalled 12 in preformed holes of composite frame structure An influence of the height of preformed holes and reinforcing mode on nodes' shear strength is discussed and reasons for failure of the ends of secondary beams are analyzed Based on the mechanism above,a formula for calculating their shear strength is established

关 键 词：框架结构 剪切强度 主次梁节点 钢筋混凝土
