Test Research on Stiffness of Loaded Concrete Beams Strengthened with Prestressed CFRP Sheets

Abstract:

In order to investigate the mechanical properties of concrete beams strengthened with CFRP sheets under load conditions, according to the reinforcement ratio, three groups of twelve concrete beams were made, each group included an common concrete beam and three prestressed CFRP sheets reinforced beams. Then the test with two-point loading was completed and the test date were obtained. On the basis of the test data, load state of concrete beams strengthened with prestressed CFRP sheets can effectively improve the ultimate bearing capacity, limit crack development and ameliorate the section stiffness.
