摘要(Abstract):

通过对24个缺口梁试件的试验,研究了配置不同类型的抗剪钢筋对缺口梁抗剪强度的影响效果、缺口边抗剪钢筋的有效作用范围和缺口高度对抗剪强度的影响等内容;分析了缺口梁端部的破坏机理,并在此基础上提出了缺口梁抗剪强度计算公式和合理的端部构造要求.
Based on shear test taken on 24 RC notched beams, this paper studies and analyzes the effect of various stirrup upon shear bearing capacity, the effective range of stirrups, the effect of height of notched end on shear bearing capacity and the failure mechanism of notched beam. Finally, a series of formulae for calculating limiting shear bearing capacity of notched beam are presented.
