Experimental Study on the Seismic Behavior of Damage RC Frame Structure Strengthened with Carbon Fiber Reinforced Polymer (CFRP) and Steel Plate
In this test, three models of concrete frame structure are made with the same dimension. The experiment of the models under low-cycle repeated load is studied. One of them is not reinforced for reference, and others are damaged to one certain degree then reinforced with CFRP and steel plate in completely uninstall cases respectively. This test is to study the effects of the two reinforcement methods to the seismic behavior of damaged concrete frame structure. Research shows that: the role steel plate in improving bearing capacity and rigidity of the damaged concrete frame structure is better than CFRP. Comparing with steel plate the CFRP can improve well damaged concrete frame structure ductility and energy dissipation capacity.
