Abstract
In this paper, reinforced concrete columns test has been conducted under repeated lateral load reversals. The test columns have been reinforced with outside lateral confinement members in addition to transverse reinforcements. For this purpose, a strainless steel and a GFRP have been employed for the lateral confinement members. Primary parameters are types, thickness and spacing of the lateral confinement members. Experimental results reveal that columns reinforced with lateral confinement members exhibit improved ductility and energy dissipation capacity in comparison with those unreinforced. It is thus concluded that the present approach can be of a useful scheme for the seismic retrofitting of reinforced concrete columns.
