An experimental study is conducted and a theoretical solution is proposed in the present study to investigate the ductile/brittle failure mode of reinforced concrete (RC) beams strengthened with an external steel plate. In the present experimental study. 6 steel plate-strengthened RC beams and 1 non-strengthened RC beam are fabricated and tested under 4-point bending loads.
