An experimental Study on the Confinement Effect of Concrete specimens confined by Single Spirals

단나선근으로 횡보강된 콘크리트의 횡보강효과

Experimental research was carried out to investigate the confinement effect of concrete specimens confined by single spirals subjected to the concentric axial compressive load. Main variables are the compressive strength of concrete, the spacing of the spiral reinforcement and the yield strength of the spiral reinforcement. Axial stress-strain curves are reported.
