摘　　要：通过集中荷载作用下五根不同单侧纵筋配筋率的有腹筋约束梁在负筋截断时的试验,研究了在纵筋截断下有腹筋约束梁的受剪破坏全过程及纵筋配筋率对抗剪强度的影响。In this paper, five restrained beams with web and different longitudinal reinforcement ratio as well as above longitudinal reinforcement truncated were tested under static point loads. On this basis, the overall process of cracking development under shear and the effect of longitudinal reinforcement ratio on shear strength was investigated

关 键 词：钢筋混凝土 有腹筋约束梁 负筋截断 纵向钢筋配筋率 受剪性能
