An Experimental Study on the Improvement of Structural Performance of Steel Fiber Reinforced Concrete Beam Using Early Age Concrete
강섬유보강 초기재령 철근콘크리트 보의 구조성능 개선에 관한 실험적 연구
Abstract
The purpose of this study is to evaluate the structural performance of Reinforced steel fiber concrete structures using early age concrete. Reinforced concrete structures using early age concrete are result in the degradation of structural performance due to crack, overload, unexpected vibration and impact load. Specimens, designed by the over 0.75% of steel fiber incorporated, were showed the ductile behavior and failed slowly with flexure and flexure-shear. Increasing the percent of steel fiber incorporated(0.25~2.0%), the ultimate shear stress of each specimen were increased 12~40% than that of specimen SSS.
