Abstract

Enhancement of properties of reinforced concrete beams involves strengthening of existing members to carry higher ultimate loads or to satisfy certain serviceability requirements. In structural engineering the introduction of advanced composite materials, particularly adhesive bonded Kevlar fabric as externally bonded retrofit materials, has offered many benefits (i.e. corrosion free, excellent strength to weight ratio, ease for site handling, flexibility to conform to any shape). The use of Kevlar fabric will enhance the flexural behavior of concrete beams. Two point loading test has to be conducted on controlled and strengthened beams by varying the wrapping system. The experimental results are compared with the analytical. The merits and demerits of application of adhesive bonded Kevlar fabric are also discussed.
