摘　　要：通过对一组 11根钢筋混凝土圆形截面无腹筋梁抗剪性能的试验研究 ,探讨了此类构件在剪跨区内斜裂缝的开展及其破坏的过程和形态特征 ,在此基础上 ,建立了圆形截面无腹筋梁抗剪承载力的计算公式 ,为进一步研究此类构件的抗剪性能提供一定的参考意见。By analyzing the test data of eleven reinforced concrete circular beams without stirrups,the developing,destroying and shape\|characteristics of inclined cracks in shear span section have been studied.A formula for calculating the shear strength of circular members is derived on the basis of the analysis.Thus,advisory opinion is provided for deeply studying the shear bearing of the similar members.
