Existing reinforced concrete (RC) columns that do not conform to current seismic detailing requirements carry the risk of non-ductile failure that can lead to catastrophic failure of the structure. The behavior of such non-ductile columns can be significantly improved by FRP jacketing to enhance the plastic hinges performance and shear strength of the columns, achieve ductile behavior of the structure, and minimize the potential collapse risk.
