Toughness Index and Post-Crack Equivalent Tensile Strength of Steel Fiber Reinforced Concrete

강섬유 보강 콘크리트의 휨 인성지수와 균열 후 등가인장강도

Steel fibers are added to concrete to improve energy absorption, impact resistance and apparent ductility, and to provide crack resistance and crack control. This study is to investigate the toughness index and post-crack equivalent tensile strength of steel fiber reinforced concrete properties on the load-deflection behaviors of the steel fiber reinforced concrete beam model specimens.
