ABSTRACT
The results of the experimental program, presented in this paper, establish the effectiveness of CFRP sheets in upgrading deficient exterior beam-column joints. The results of CFRP repaired and strengthened specimens were compared with their corresponding control specimens and, in general, it was observed that CFRP sheets improve the shear resistance and ductility of the RC joints to a great extent. The failure of CFRP upgraded beam-column joints due to debonding (bulging) was examined and it was observed that at higher stage of loading there was significant yielding in beam reinforcing bars that allowed cracks to widen in the beam region which in turn ultimately tore the CFRP sheets.
