| Abstract: | The mechanism of the reinforced concrete structure strengthening by carbon fiber reinforced polymer is analyzed. It is pointed out that the main effects of carbon fiber reinforced polymer are to resist pull, confine crack, and enlarge the effective press area of concrete. A new and practical strengthening design and calculation is proposed through integrating the calculation theory of the bearing capacity of bending component of reinforced concrete. The method is proved to be correct and reliable through comparison with experimental and actual application. So it can be used in the design of actual project. |
