The objective of this paper is to investigate the performance of slender square reinforced concrete (RC) columns strengthened with carbon fibre reinforced polymer (CFRP) jackets subjected to eccentric loading. Tests were conducted on eight RC columns strengthened with CFRP jackets, and another eight unstrengthened ones served as reference specimens. The main variables explored in this test programme include: (a) load eccentricity (0–150 mm); (b) with or without CFRP strengthening; and (c) CFRP configuration (unidirectional and bidirectional). Compared to those unstrengthened RC specimens, the test results showed that no obvious strength increase was observed for specimens confined by unidirectional CFRP jackets, while an increase of 22·8–61·8% was obtained for those strengthened by bidirectional CFRP jackets. The longitudinal fibres were effective in enhancing load-carrying capacity of slender RC columns subjected to eccentric loading.
