Many of the existing reinforced concrete structures do not meet the strength and ductility requirements stated by the current earthquake resistant design codes in many countries that are in earthquake prone zones. These types of structures may suffer different levels of damage during major earthquakes. Experimental and theoretical investigations on strengthening these types of structures using new, high strength and easily applicable materials are vitally important to prevent loss of human life and economic loss. In this study, the preliminary results of an experimental study on repaired and/or strengthened concrete cylinders and symmetrically reinforced concrete members with rectangular cross-section that were damaged formerly is presented. Carbon fiber reinforced plastic sheets are used for strengthening, while epoxy injection and high strength repair mortar are used for rehabilitation.
