Abstract: The study represents the local behaviour of strengthened reinforced concrete short corbel by external bonding of Carbon Fibers Reinforced Polymer fabrics. For the experimental program total six corbels were casted with two control sample and four strengthened samples with externally CFRP Fabrics. Strut-n-tie method is used for the design of corbel, which is effective method for analyising forces in the corbel. Comparison for the ultimate load v/s deflection graphs were studied for the control and strengthened specimens. Test results showed improvement in the ultimate load carrying capacity for the strengthened samples with horizontal and inclined wrapping on the faces of the corbel. Full wrapping by the unidirectional CFRP Fabrics in the horizontal manner showed higher results compared with the control and inclined (45˚) orientation of CFRP Fabrics.
