Review of Research on Fiber Reinforced Polymer(FRP)Reinforced Concrete Structures
Because of the characteristics of high tensile strength,low density and excellent corrosion resistance,the new building material of fiber reinforced polymer(FRP)is a promising engineering material.At present,the tradi-tional reinforced concrete structure has the problem of easy corrosion of steel bars,which cause great economic losses to the society and high costs of maintenance and repair.That replacing steel bars with FRP bars in specific environ-ments can not only effectively solve the durability of reinforced concrete structures,but also further optimize the working performance,prolong the service life and reduce maintenance costs.Firstly,the research progress of FRP reinforced concrete structures at home and abroad are briefly described in the paper.And then,the characteristics of FRP bars,FRP reinforced concrete and prestressed FRP reinforced concrete structures are expounded.Finally,the important development issues of FRP reinforced concrete structures are summarized,and the development prospects are prospected in future.
