摘　　要：作为一种新兴的高性能材料,纤维增强复合材料(FRP)筋由于高强、耐腐蚀等优点,已经成为传统建筑材料的重要补充,正逐步应用于土木工程领域。因此,FRP筋与混凝土相结合将是未来土木工程领域的热点问题,但是目前对FRP筋混凝土梁的抗剪机理并没有统一的理论,这大大限制了FRP筋在实际工程领域的应用和推广。本文通过对国内外相关研究成果及规范的追溯,从试验研究、数值模拟和理论分析三方面梳理了FRP筋混凝土梁抗剪性能的研究成果,总结了不同研究对象、研究方法下得到的抗剪承载力计算公式,以期为今后FRP筋混凝土梁抗剪的研究与设计提供参考和建议。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.
