Abstract:
A short method based on crack arrest concept has been proposed for the prediction of the cracking stress of continuous wire reinforced concrete. The comparison of theoretical and experimental results has demonstrated the validity of this method. The method is further extended to the case of the cracking stress of three dimensional randomly distributed steel fibre reinforced concrete. In this regard, first the effective spacing of short fibres is determined by considering their directional efficiency and length efficiency in restraining the crack propagation. The theoretical cracking stresses for various volume fractions of steel fibres are determined and compared with the experimental results.
