Abstract: Aiming at the problems of large calculation error of bearing capacity and low accuracy of bending performance analysis in the analysis of bending mechanical properties of carbon fibre reinforced reinforcement, an analysis method of bending mechanical properties of carbon fibre reinforced reinforcement under reciprocating load is studied in this paper. Firstly, the secondary reinforcement and carbon fibre cloth are selected as reinforcement materials, and the elongation of carbon fibre cloth is determined to complete the carbon fibre reinforcement of reinforcement. Then, the elastic modulus, bearing capacity and deflection parameters of CFRP reinforcement under reciprocating load are calculated; Finally, the convergence conditions of the flexural mechanical properties of the reinforced steel bar are set to complete the flexural mechanical properties analysis of the carbon fibre reinforced steel bar under reciprocating load. The experimental results show that the analysis accuracy of bending mechanical properties of this method is up to 98%.
