| 摘 要： | 研究了在钢筋混凝土构件受拉面上粘贴GFRP板材进行结构加固时的加固程度。参考钢筋混凝土理论对双筋矩形截面梁进行了正截面内力分析，得出了判别加固梁破坏形态的判别标准，并据此推导了避免超加固的最优板厚。

| Abstract: | Studied the strengthened level of the reinforced concrete member when by plastering the GFRP sheets on its tension face. Analyzed internal force of the right section by reference to the reinforced concrete theory. Concluded the discriminating criterion of the damage shape of the strengthened beam. Deduced the optimum slab thickness to avoid over-reinforcement. |
