Semi-prefabricated FRP (Fiber Reinforce Plastic) bar concrete ductile simply supported beam

The utility model relates to a semi-prefabricated FRP rib concrete ductility simply supported beam. Simply supported beam, the beam comprises a beam body and an FRP rib framework embedded in the beambody, the beam body comprises a main beam body and an ECC ductile block obtained through prefabrication, a reserved cavity used for containing the ECC ductile block is formed in the portion, corresponding to a pressed area of the beam body, of the main beam body, the ECC ductile block is embedded into the reserved cavity after the main beam body is poured, and the FRP rib framework is embedded into the main beam body. Compared with the prior art, the concrete on the pressed side of the plastic hinge area is replaced by the ECC ductile block restrained by the large-strain composite material cloth; the ductile block is a prefabricated part. The replaceability of the plastic hinge can be realized; improving repairability, large-scale dismounting caused by the fact that an original structure cannot be repaired due to
