Results from tests of one rectangular and one T-beam are reported. The beams were strengthened by epoxy-bonding a 1/4 in. (6 mm) thick Glass Fiber Reinforced Plastic plate along the tension face. It is shown that the nominal load carrying capacity of the beams was significantly increased. The parametric study presented indicates that the method is most effective when applied to beams with low flexural steel reinforcement ratios.
