摘　　要：分析了 CFRP 加固梁粘结破坏机理及相应的计算模型,在前人研究的基础上,根据混凝土二轴破坏准则(Tasuji-Slate-Nilson 准则)推导出四点加载情况下的 CFRP 抗弯加固梁粘结破坏极限荷载的计算公式,并由试验资料回归出计算公式中的待定系数。最后,将计算方法与其它三种计算方法及试验值进行对比,提出的计算方法可以得到更加合理的计算结果。In this paper, bond failure mechanism of strengthened beams and calculation model is analysed. According to Tasuji-Slate-Nilson Rule, the formula of calculating ultimate strength of strengthened beams damaged due to bond failure is deduced on the base of research results of predecessores, and coefficients in this formula are confirmed based on testing data. Finally, calculating method proposed in this paper is contrasted with three other methods and testing data, and more reasonable results can be gained.
