摘　　要：为研究跨裂缝粘钢加固对裂缝截面抗剪能力的提高幅度及内在作用机理,探讨跨裂缝粘钢抗剪加固承载能力的计算方法。通过12根短梁的直剪破坏试验研究,以粘贴位置、端头锚固条件、裂缝界面状况为主要相关因素,对跨裂缝粘钢加固混凝土构件裂缝截面的抗剪承载力、抗剪破坏特征进行了研究。To study the effectiveness and internal function mechanism of binding steel plate across the crack to improve its shear capacity and study its calculation formula,direct shear experiments on 12 short beams were done,with binding position,head condition of adhesive joint,crack interface condition being the main related factors.Investigation was also held on the shear capacity and shear failure modes of cracked sections of these short beams.

关 键 词：裂缝 粘钢加固 抗剪承载力
