Abstract: In recent years, many bridges have been built and put into operation. Many problems have ap-peared in the operation. Therefore, the strengthening of bridges is particularly important. This article mainly introduces the composition and performance of FRP materials, and the application of FRP materials in rein-forcement technology. The role of the new FRP reinforcement technology in reinforced concrete beams and columns has also been analyzed, particularly in terms of resistance to bending, shear resistance, and durability. It also explains some of the existing technical, construction and management issues. And how should we deal with and solve these problems in order to achieve a better grasp of this new type of reinforcement technology.

Keywords: FRP reinforcement technology; Durability; Bending resistance; Shear resistance
