Experimental works are reported to assess the response of reinforced concrete (RC) beams under repeated loading, with different reinforcing bars. A three-point loading was done with increasing loading magnitudes and comparisons are made on crack recovery capabilities and feasibility of activated network healing, of three different types of reinforced concrete beams; first with the steel deformed bars, secondly with steel threaded bars and finally with superelastic alloy (SEA) threaded bars. Strong crack recovery and effective self-repair was achieved for the SEA-RC beam specimens.
