Abstract: As a new kind of high performance material, fiber reinforced composite (FRP) bars have become an important supplement to traditional building materials due to the advantages of high strength and corrosion resistance, and are gradually applied in the field of civil engineering. Therefore, the combination of FRP bars and concrete will be a hot topic in the field of civil engineering in the future. However, there is no unified theory on the shear mechanism of FRP reinforced concrete beams, which greatly limits the application and promotion of FRP bars in the field of practical engineering. In this paper, the research results of the shear performance of FRP reinforced concrete beams are sorted out from three aspects, namely experimental research, numerical simulation and theoretical analysis by tracing the relevant research results and norms at home and abroad. The calculation formulas for shear bearing capacity obtained under different research objects and methods are summarized, expecting to provide reference and suggestions for the future research and design of FRP reinforced concrete beams.

Key words: concrete beam, FRP bars, shear performance, standard formula, composites
