“…Fiber reinforced polymer (FRP), for the advantages of non-enhanced structural section and deadweight, easy construction, high tensile strength, excellent corrosion resistance, good fatigue strength, non-magnetic and non-conductive properties, wear resistance, easy cutting, low density, etc, has been applied to the reinforcement of local parts of bridge structures [4][5] . The reinforced structure is a new composite structure composed of the existing bridge structure, FRP material, and epoxy resin colloid.…”

Due to the increase of service life, the phenomenon of performance degradation of bridge structures becomes more and more common. It is important to strengthen the bridge structures so as to restore the resistance level and extend the normal service life. CFRP materials are thus used for the assembly reinforcement of bridges for the advantages of high strength, light weight, corrosion resistance and long-term stability of physical and chemical properties, etc. In view of this, based on the previous theoretical study and the established formula of the interfacial shear stress of CFRP reinforced steel beam and the normal stress of CFRP plate, this paper discusses the sensitive parameters that affect the interfacial interaction of CFRP strengthened beam structures. Through the analysis, the priority design indicators and suggestions are accordingly given for the design of reinforced beam structures. The conclusions of this paper will provide guidance for the interfacial damage control of CFRP reinforced steel beam structures.
