Prestress shear-resistant reinforcing method and shear-resistant bearing capacity calculation method for reinforced concrete beam

The invention discloses a prestressed shear reinforcement method and a shear bearing capacity calculation method of a reinforced concrete beam. The shear-resistant reinforcement method comprises the steps of chiseling and grooving, FRP rib tensioning and glue filling and TRC reinforcement. The shear bearing capacity calculation method comprises the following steps: determining the distance and the diameter of FRP bars on the side of a reinforced concrete beam and stirrups in the beam after reinforcement, the number of TRC layers and the specification of a fiber woven mesh, and determining the geometric dimension of a component; determining mechanical parameters of the carbon fiber bars, the stirrups, the fiber woven meshes and the reinforced concrete beams; and a shear bearing capacity calculation model of the reinforced concrete beam after TRC composite embedded prestress FRP shear reinforcement is established, and the shear bearing capacity of the reinforced concrete beam after reinforcement is calculated.
