Influence of Using CFRP on Damaged Columns Repaired with Two Different Materials

In this work, the behavior of reinforced concrete columns under biaxial bending is studied. This work aims at studying the repairing of columns by using carbon fiber reinforced polymer (CFRP). The experimental work includes investigation of six reinforced concrete columns (150*150*500mm) tested under several load conditions. Variables considered in the test program include; effect of eccentricity and effect of repairing material (Epoxy and Sika repair). Test results are discussed based on load – lateral deflection behavior and ultimate load. The CFRP reinforcement enhances the behavior of damaged columns. The using of Epoxy material was more significant effect than the Sika repair material Keywords: Repaired, RC Columns, Biaxial Bending, CFRP, Experimental
