Abstract [en]

The repair of reinforced concrete (RC) beams with carbon fiber reinforced polymers (CFRP) is experimentally investigated in this study. The four T-section reinforced reactive powder concrete beams with many locations of circular opening were repaired by CFRP and investigated under pure torsion. The repairing beams were tested to obtain the effect of the amount of CFRP laminate on beams cracking and ultimate torque behavior, angle of twist and failure modes. The results obtained from the adopted repairing technique showed a significant effect of external high strength CFRP laminates on effectively restore of section solid of 85% of crack torsional strength effectively restored. In addition, the results show that effectively restoring of section opening by 82%-80% of crack torsional strength, and the adopted repairing technique gives a good strength to the beams.
