Abstract

This paper aims to evaluate the improvement of load carrying capacity of reinforced concrete beams strengthened by Carbon Fiber Reinforced Polymer (CFRP) strips. Sixteen reinforced concrete beams with a cross section of 120x200 mm and a total length of 2300 mm, were fabricated, strengthened, and loaded up to failure. The results showed that the externally bonded CFRP strips increase the flexural and shear capacities of reinforced concrete beams. For example, the flexural capacity of strengthened beams increased by 12-40%, while the shear capacity increased by 10.5-52.6%. The stiffness enhancement varied from 10 10 79% depending on the applied strengthening mode. A reduction in deflection for all strengthened beams was observed and recorded.
