Abstract: 
Research has shown that steel fibre reinforced concrete (SFRC) can enhance many of the properties of concrete, including improved post-cracking tensile capacity, enhanced shear resistance and increased ductility. The improved toughness, ductility and damage tolerance of SFRC make it an ideal candidate for use in the blast resistant design of structures. There is limited research on the behaviour of SFRC under impact and blast loading and some of this data is conflicting, with some researchers showing that the additional ductility normally evident in SFRC is absent or reduced at high strain loading. On the other hand, other data indicates that SFRC can improve toughness and energy-absorption capacity under extreme loading conditions. This paper presents the results of an ongoing experimental program which is examining the behaviour of SFRC columns under simulated blast loading. In the experimental program half-scale SFRC columns were constructed and exposed to different simulated blast pressure–impulse combinations using state-of-the art shock-tube testing facilities at the University of Ottawa. The columns were designed according to CSA A23.3 (Canadian) standard as first-story columns and were constructed using a self consolidating concrete mix and varying quantities of steel fibres (0-1.5%).
