Abstract:
Data describing the strength and deformation characteristics of repaired concrete beams is limited. A study was undertaken to compare the strength and deformation characteristics of repaired beams to those of the original beams before failure. Seven beams that failed in shear were repaired and tested. The repair technique consisted of straightening the longitudinal steel, chipping out concrete in the failure zone, and placing fiber reinforced concrete in the damaged zone. The repaired beams had a less violent failure in comparison to the original beams, and generally had higher shear strength capacities than in the original beams.
