| Abstract: | In order to improve the shear capacity of concrete beam,a new composite reinforcement technique that pasting CFRP on both side of the end of the concrete beam and prestressed CFRP at the bottom was used. This paper designed five concrete beams without web reinforcement to carry out static loading experiment and analyzed oblique cross-section mechanical properties of the beams which reinforced by prestressed CFRP through experiment, researched the impact of concrete beams on the shear strength in different reinforcement and made a technical conclusions and recommendations which had a certain practical value. |
