| Abstract: | Many bridges in service are suffering defects and design inadequacy, which can not meet the needs of modern traffic. Aimed at the high-strength and light characteristics, carbon fiber is applied to bridge strengthening. The paper put forward the calculation theory of the bending beam of the carbon fiber reinforcement and focuses on the analysis of the balanced-reinforced beam. |
