摘　　要：文章通过对一组不同剪跨比、不同混凝土强度等级下的圆形截面钢筋混凝土无腹筋梁 在集中荷载下的抗剪试验研究，分析总结了此类构件斜裂缝及次生裂缝出现和发展的规律和特 征以及斜截面破坏过程、形态的规律和特点。为进一步研究圆形截面构件的抗剪性能提供参考意 见。By testing and studying 11 concentrated and loaded concrete circular reinforced concrete beams without web reinforcement in varying shear span effective depth ratio and strength of concrete, the paper analyzes and summarizes the developing regular pattern characteristics of cracks and shear failure characteristics. It also puts forward suggestions for further study on the shear strength of circular reinforced concrete members.

关 键 词：圆形截面 剪切破坏特征 钢筋混凝土无腹筋梁
