In this paper experimental investigations were conducted considering the interaction of fiber length fiber volume fraction and matrix strength on the fracture toughness of steel fiber reinforced concrete (SFRC) The method is based on the evaluation of tension softening in the fracture process zone by means of a reverse analysis of the cohesive force model As the result the following aspects were derived Both of the fiber-bridging stress and the fracture toughness in terms of the J-mtegral value of the SFRC increase as the increase in cement-water ratio (C/W) of the matrix and the extent becomes markable with'the longer fiber The interaction of fiber aspect ratio (l_f/d), fiber volume fraction (V_f) and C/W on the, fracture toughness of the SFRC can be expressed by the parameter of (l_f/d)√<V_f>√_<C/W> in the high correlation with the fracture toughness
