Distortion And Stiffness Analysis Of CFRP Reinforced Concrete Beam

According to the statistically analyzing on the experiment results of crack, stiffness and deformation of carbon fiber reinforced concrete beam at home and abroad, systematically theoretical analysis and finite element analysis computer simulation have been carried out to study concrete beams reinforced by carbon fibersheet in this paper. The details are as followings.(1) This paper researches on the mechanism of crack, and gets crack spacing andcrack width formula on the base of theoretically analysis. The theory results can be thought right by comparing them to the experiment results and simulation results.(2) This paper researches on the stiffness of carbon fiber reinforced concrete beams. This paper takes into consideration both the steel yield and not, and achieves the stiffness formula to calculate carbon fiber sheet reinforced concrete beams. This paper researches on the deformation of the carbon fiber reinforced beams based on the stiffness formula given in this paper. This paper compiles programs with Visual C++ to calculate crack spacing, crack width, stiffness and deformation.(3) This paper does finite element analysis on the beams, gets the crack distribution, strain figures and load-displacement curves of the beams reinforced with different carbon fiber sheet layers. This paper discusses the effect of slip.(4) Finally, this paper summarizes the whole thesis and gives construction design suggestions and deficiency...
