| Abstract: | External confinement by the wrapping of fiber-reinforced polymer (FRP) sheets is a very effective method for the strengthening
and retrofit of round concrete columns. The stability and strength of concrete columns confined by carbon FRP jackets in which
the fibers are oriented in the hoop direction was studied. Stability tests were conducted on hinged plain and confined concrete
columns of different slenderness. The theoretically predicted critical stress at the on set of in stability was compared with
that obtained experimentally, and a good agreement between them was observed.
