In this paper, shear strengthening of RC beams with insufficient shear reinforcement by a new proposed technique, Prestressed Embedded Through-Section Bars (PETSB), was studied experimentally. This technique consist of boring holes through beam web and embedding steel bolt and tightening the bolt to the pre-determined prestressing force. In order to investigate the influence of the proposed strengthening method, a test program including 10 RC Beams with dimensions of
considerably more effective in ductility and energy dissipation improvement.
