Abstract: 
This paper presents the results of an experimental study on the behaviour of CFRPconfined short concrete columns with low unconfined concrete strengths subjected to eccentric loading. A total of twenty four (24) concrete columns were tested. Three unconfined and three reinforced concrete columns were used as control specimens. Confinement was provided by using CFRP wraps of different heights and spacing. Different confinement schemes were used to determine the effect of schemes on the load carrying capacities of eccentrically loaded columns. All the columns were tested in uniaxial compression, with the load applied at an eccentricity from centre of the column. Results indicate that load carrying capacities of CFRP-confined concrete columns was enhanced in all confinement schemes used during the study and use of CFRP wraps to improve performance of eccentrically loaded concrete columns was found to be an effective method.
