Abstract
Abstract In the present study, a comparison has been conducted to investigate the efficiency of using the near-surface mounted steel bars technique for strengthening and repairing the damaged reinforced concrete corbels. Three configurations for installing the steel bars have been considered; horizontal, diagonal, and combined. Results revealed that is better to use this technique within the early stages of loading. Moreover, results proved that the strengthening by the diagonal scheme yielded a better response in terms of cracking and failure loads with values of 166 and 95% relative to the control specimen. Also, it is found that for damage of 45%, the horizontal arrangement yielded the highest failure load of 99% whereas for damage of 65%, the diagonal system yielded the optimum value of 50% relative to the control specimen.
