Mechanical Properties on the Pull-Out Response of Steel Fibers Embedded in Cementitious Matrices

시멘트 매트릭스 내 강섬유의 매입 일반에 관한 성능

The main objective of this study is to provide a parametric evaluation of the pull-out response of steel fibers embedded in cementitious matrices. The various parameters controlling the behavior of the bond stress versus end slip relationship are analyzed; their effects on the entire pull-out load versus end slip response and the corresponding pull-out energy up to total pull-out are investigated. Also discussed are the effects of the fiber length, the water/binder ratio of the mixtures and embedded length.
