Structural Performance of Corrosion Damaged Reinforced Concrete Beams with Glass Fibre Reinforced Polymer Laminates

摘要

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 × 250 × 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%.
