The Investigation of Blocks on High Strength Concrete
고강도 콘크리트 부재의 응력블록에 관한 검토
Abstract
The object of this study was to investigate the flexural stress blocks of High Strength Concrete Members under monotonic loading. Such a stress block should be clearly idealized before High Strength Concrete can be used with confidence in Structural Members. The principal test variables were the Compressive Strength of Concrete, the percentage of longitudinal reinforcement and the spacing of confinement reinforcement. The rectangular stress block of the present ACI Building Code was found to give acceptably conservative flexural strength predictions over the entire range of concrete strength from 280kg/crd (4Ksi)to 1050kg/crd( 15Ksi)
