초록
본 연구는 강섬유보강콘크리트의 인성을 평가하는 기존의 다양한 방법을 검토하고, 인성지수를 규명함에 있어 초기균열하중에 여러 가지 곱을 사용하는 방법의 문제점을 지적하였다. 인성을 규명하기 위해 하중-처짐 곡선대신 하중-CMOD 곡선을 사용하였다. 물/시멘트비(0.35, 0.40, 0.45, 0.50)와 섬유혼입량(0.0%, 0.5%, 1.0%, 1.5%)을 변수로 하여 노치를 가진 강섬유보강콘크리트 시험체를 3등분점 가력하였다.
Abstract
This study reviewed various current methods of evaluating the toughness of steel fiber reinforced concrete specimens and criticized the use of various multiples of first-crack deflection to define toughness indices. The load-CMOD curve to determine toughness, instead of load-deflection curve, was used. The notched steel fiber reinforced concrete specimens with different water/cement ratio(0.35, 0.40, 0.45, 0.50) and fiber volume content(0.0%, 0.5%, 1.0%, 1.5%) were tested under third point bending.
