PRESTRESSING ANCHORAGE SYSTEM OF A CARBON FIBER REINFORCED POLYMER PLATE FOR FLEXURAL STRENGTHENING OF A CONCRETE STRUCTURE, CAPABLE OF EFFECTIVELY PRESTRESSING A CFRP PLATE

摘要

PURPOSE: A prestressing anchorage system of a carbon fiber reinforced polymer plate for flexural strengthening of a concrete structure is provided to effectively repair and reinforce a concrete structure, and to improve bearing capacity.;CONSTITUTION: A prestressing anchorage system(200) of a carbon fiber reinforced polymer plate for flexural strengthening of a concrete structure comprises a test object(110), a carbon fiber plate(120), a moving end(130), a fixed end(140), a hydraulic device(150), and a movable end. The test object is composed of a concrete beam or a slab. The carbon fiber plate is attached on the surface of the test object as a reinforcing material. The moving end controls prestressing force, and applies the prestressing force to the carbon fiber plate. The fixed end fixes the end of the carbon fiber plate. The hydraulic device is installed in the moving end to apply the prestressing force to the carbon fiber plate, and is fixed to the movable end. After the prestressing force is applied to the carbon fiber plate, the movable end is coupled to the test object.;COPYRIGHT KIPO 2010
