Abstract
The report reviews research studies relevant to structural strengthening existing reinforced concrete members and frames. The majority of these studies dealt exclusively with restoring or improving seismic resistance of concrete columns and frames. A number of case histories where various strengthening techniques were applies in practice are reviewed. Most studies identified ultimate failure in the strengthened structures as primarily due to failure of the joining elements. Improved load resistance and ductility in concrete structures have been reported in most of these studies.
