The pullout behavior of steel fibers has a significant influence on the overall mechanical properties of steel fiber reinforced concrete. The embedment length of steel fiber is one of the principal factors which influence the pullout properties of a single fiber. In this study, therefore, the effect of embedment length of fiber, being the principal factor, was examined experimentally. The effect of the matrix concrete strength for both high strength and normal strength and that of the fiber geometry were examined as well. From the experimental results a pullout model is derived taking the embedment length as a parameter.
