Experimental Evaluation of Damaged Rectangular RC Beams Repaired with NSM-CFRP

Résumé

An experimental study has been carried out on damaged rectangular reinforced concrete (RC) beams, repaired with near surface mounted (NSM) carbon fiber reinforced polymer (CFRP) materials. A total of 32 specimens were loaded to failure in a 4 points flexural test. The parameters considered are: the rate of damage (20%, 40% and 60%), the rate of strengthening and the type of strengthening materials (rods and strips). Concrete compressive strain, CFRP strain, ultimate strength and load-deflection have been recorded to evaluate the response of the specimens. Results clearly demonstrate that the strengthening with NSM-CFRP can enhance the structural performance of RC beams in terms of both maximum strength and deformation. The effects of test parameters are evidenced and compared.
