| Abstract: | Through the application of elasticity theory,this article analyzes the pre-and-after conditions of carbon fiber reinforced concrete beams,and considering the whole process of the flexural reinforcement beams under preload it examines the mechanism of carbon fiber reinforced beams.Also,the beam ultimate load bearing capacity is calculated and then the calculation with the experimental results is compared.The findings show that the stiffness of the reinforced concrete beam strengthened by FRP is apparently higher than that of the ordinary reinforced concrete beam,which is of great significance to improve the durability of reinforced concrete beams. |
