摘　　要：将粘钢板、碳纤维、玻璃纤维等加固材料的加固方案统一归类为“粘贴加固”.结合试验观察结果,将粘贴加固受弯构件破坏分为3类破坏形态,并给出各自的承载力计算公式和使用范围.通过对比发现计算结果与试验结果基本一致,这表明粘贴加固技术是可以用统一的计算公式来取代现有的几种加固公式.这将有助于设计人员根据各种加固材料特性,结合工程实际选择最优的加固方案.This paper submits such methods which sticking high strength materials to flexural member’s edge as sticking reinforcement. Combined with the conclusion of test. The writer classifies the design destructive forms of bonded-strengthened beams into three categories, and gives the relevant integrated formula for calculating flexural capacity and applied boundary. By means of the comparison, it can be found that the paper’s formula had the same result with tests’. It also indicates that the flexural capacity of sticking reinforcement members can be taken as only one formula. This will help designers based on each of sticking material’s characteristic and engineering’s condition to choose the best of reinforced method.
