This paper presents the results of an experimental investigation on the structural performance of corrosion damaged reinforced concrete beams strengthened with UDCGFRP. A total of five beam specimens 150 X 250X 3000 mm were cast and tested for the present investigation. One beam specimen was neither corroded nor strengthened to serve as a reference. Two beams were corroded to serve as a corroded control. A reinforcement mass loss of approximately 10% and 25% were used to define medium and severe degrees of corrosion. The remaining two beams corroded and strengthened with GFRP. The experimental results showed distinct enhancement in ultimate strength by 86% and ductility by 62%.
