A comprehensive review and analysis of shear strengthening of RC beams with external prestressing bars

Shear failure in reinforced concrete (RC) structures, characterized by their sudden and brittle nature, often results from inadequate shear reinforcement or degradation due to aging or increased loading demands. To increase shear capacity, various retrofitting techniques have been developed, with ex...
