Through the experiment of reinforcing and reinforcing RC beams with 9 carbon fiber sheets, this paper mainly studies the effects and the effects of the amount of carbon fiber sheets on the flexural behavior of RC beams. Experimental results show that the method of using carbon fiber cloth to improve the normal section bearing capacity of RC bent members is effective. The flexural bearing capacity of test beam is obviously improved after carbon fiber cloth is affixed. In addition, a computer analysis program is also developed for theoretical analysis, and a simplified calculation method of flexural capacity is proposed. The method is in good agreement with the experimental data and theoretical analysis to meet the requirements of the actual engineering design.
