The finite element software Abaqus is used to simulate the reinforcement of the steel box girder with CFRP sheets. The wave anchor anchorage system clamps the carbon fiber (CFRP) sheets and anchors them in the tensile zone at the bottom of the steel box girder. The temperature method is used to simulate the prestress applied to the steel box girder in the actual project, and the stress of the steel box girder in the project example is compared to analyze the mid span deflection of the steel box girder; With the change of stress and strain, the mid span deflection of prestressed CFRP sheet to steel box girder is analyzed; Stress; The improvement of strain sum shows that prestressed CFRP has good reinforcement effect for flexural members.
