Long-Term Performance Research on Reinforced Concreted Beams with Pre-Stressed CFRP Plate
With the continuous development of science and technology, the method of using the pre-stressed carbon fiber on the concrete structure, in particular on the bridge structure has become a research direction by the domestic and foreign scholars. In this paper, it has done the long-term test for the civil carbon fiber in the library on the base of the research of reinforced concreted beams with pre-stressed CFRP plate, and has observed the slip of the carbon fiber fixed on the side of the tension anchor. The results showed that: when put 50% of the ultimate stress of the carbon fiber on the carbon fiber, under the action of long-term tension, the variation of carbon fiber and the slip of the carbon fiber fixed on the side of tension anchor can all achieve intended purpose of the experimen ,which provides the theoretical data on the long-term performance research of the civil carbon fiber reinforced on the concrete structures.
