| 摘 要： | 对TRC薄板加固RC梁粘结界面应力状态进行了理论分析,得出结论:粘结界面上存在剪应力,该剪应力大小与截面上弯矩成正比,并且和加固层与原混凝土梁之间的弹性模量比相关;提出改善加固梁破坏形态、提高加固效果的措施。

| Abstract: | Flexural bonding interface stress theoretical analysis of reinforced concrete beams strengthened with textile reinforced concrete sheets. The results show that: Exists on the shear stress in the bonding interface, and is proportional to the section on bending moment, and is related to elastic modulus ratio between the reinforced concrete sheets and the old concrete Beams; Propose measures to improve reinforcement beams failure modes and the reinforcing effect. |
