摘要
粘钢加固或纤维增强材料加固钢筋混凝土结构构件是一种广泛采用的技术,用于改造或增强现存的损伤或强度不足的结构构件.加固构件常发生局部粘结锚固破坏,着重研究局部粘结锚固破坏机理及影响因素,并采取桁架机制和梁机制导出粘贴片材的合理锚固长度.
<Abstrcat> Bonding by epoxy resins of metallic or nonmetallic plates to the tension face of a reinforced concrete (RC) member is widely used to strengthen damage d RC structures. The failure of the reinforced member is usually due to delamina tion of plate from the beam. This paper is focused on mechanism of delamination failure and its effect. Beam model and truss model are introduced to obtain reas onable bonded length.
