Premature plate end debonding failure is the main weakness of plate bonded strengthened beams which can be minimized by end anchors. The main objectives of this research were to study the behaviour of steel plate and CFRP laminate strengthened r.c. beams, the effects of U and L shape end anchors to prevent plate end debonding and the effects of L shape intermediate anchors to eliminate premature shear. Nine rectangular beams were tested. Design methods were proposed to obtain the dimensions of steel plate and CFRP laminate. U and L shape end anchors were used on steel plate and...
