The use of discontinuous steel fibres in concrete as non-conventional mass reinforcement has long been recognized that ameliorates the post-cracking characteristics of concrete, provides for crack propagation control and increases energy absorption capability in the tensile regime (Karayannis 2000a). The ability of SFC to overcome to some extent the limitations of concrete and to convert its brittle behaviour to a ductile one has well been established. SFC beams under flexure (Ashour et al. 1993, Chalioris 2013a), shear (Kwak et al. 2002, Chalioris et al. 2011, Chalioris 2013b) and torsion (Chalioris et al. 2009, Karayannis 2000b) have been tested to assess the favourable influence of the used steel fibres.
