Abstract—Combined with the research results of scholars, analyze and summarize the research status of FRP from the main factors affecting reinforcement effect, the calculation formula of shear bearing capacity, bond-slip relationship, nonlinear finite element analysis. Then analyze and consider the practical application of FRP in the bridge reinforcement. The analysis concludes: (1) FRP type, spacing, binder, effective anchorage length, FRP number, the strength of concrete will affect final reinforcement effect; (2) the calculation formula in the existing FRP specification should be revised in practical application; (3) the relationship of the bond-slip will have an effect on the reinforcement and analysis of bridge; (4) the finite element analysis of FRP can be more accurate to analyze the effect of bearing capacity of strengthened bridge. With the study deeply of the performance characteristics and application methods of FRP, it will be applied more in the bridge reinforcement and the reinforcement effect will be greatly improved.
Index Terms—FRP, shear reinforcement, finite element analysis, application.
