Experimental Research Of Prestressed Reinforced Concrete Shear T Beam Using Self-anchorage CFRP Of U Shape

According to the prestressed CFRP reinforced belt stick their precariously anchor structure, it is easy to have the problem of detachment, this research subject developed a new type of mechanical anchorage. Through the T-shaped prestressed beams CFRP shear reinforcement, the reaserch aims to verify the reliability of the anchor. Acquisition test data, and talking about peak ling reinforced concrete beam around the u-shaped "T" of prestressed CFRP shear reinforcement test data are compared, the main work and results are as follows:1. In the test, compared with circle "U" shape of CFRP without adhering shear reinforcement, shear reinforcement of prestressed concrete continuous beam can significantly improve the shear capacity and stiffness level;2. In the test, observing the shear failure process and pattern of the u-shaped prestressed CFRP without cohering shear reinforce continuous concrete beam in the negative moment section, and discuss the shear mechanism;3. The research mainly analysis the factors preloading level,value of prestressed and soforth, affecting the damage form and the performance of reinforced beam, and setting up a corresponding calculation formula of shear capacity, and compared with the value is used in the comparison.
