AN EXPERIMENTAL INVESTIGATION ON FLEXURAL PERFORMANCE OF RC BEAMS WITH TENSION SIDES STRENGTHENED WITH SIFCON PLATE

Experimental investigations were conducted on flexural performance of reinforced concrete (RC) beams with tension sides strengthened with slurry infiltrated fiber concrete (SIFCON) plate. As a result, we reached the following conclusions: (1) Ultimate load of RC beams can be raised nearly twice as large as that of un-strengthened RC beams by this strengthening method. (2) Peeling of SIFCON plate can be prevented up to ultimate load only by adhesive bonding. (3) There is a problem that RC beams strengthened with carbon fiber reinforced plastic plate fail brittlely due to plate-peeling. However, this technique has a possibility of solving the problem.
