Abstract
In this paper, the compressive strength and ductility enhancement of concrete by lateral confinement of carbon-fiber sheets(CFS) have been studied experimentaly with cylinder specimens and square short columns reinforced externally by CFS. Test variables were amount of lateral reinforcement by CFS and space of hoop bars. Test results showed that lateral reinforcements by carbon-fiber sheets provided lateral confinement successfully for the concrete specimens and were more effective for ductility enhancement than for strength increase, and that the lateral confinement coefficient of cabon-fiber sheets increased according to narrowing the space of hoop bars in the double lateral confinement made by CFS and hoop bars.
