To　investigate　the　mode　I　fracture　behavior　of　SFRC　(Steel　Fiber　Reinforced　Concrete)　at　low　temperatures,　3D　meso-scale　models　of　SFRC　specimens　with　different　steel　fiber　volume　fractions　(Vf　=　0.0　%,　0.5　%,　1.0　%　and　1.5　%)　were　developed　by　means　of　finite　element　analysis.　The　corresponding　failure　patterns　as　well　as　fracture　properties　were　obtained　by　three-point　bending　simulations　at　low　temperatures.　SFRC　is　regarded　as　a　multiphase　material　composed　of　mortar,　aggregate,　ITZ　(Interface　Transition　Zone)　and　steel　fiber　at　the　mesoscopic　scale.　The　comparison　between　simulation　results　and　the　test　results　verifies　that　the　meso-scale　numerical　model　could　well　describe　the　mechanical　behavior　of　SFRC.　The　simulation　results　show　that　the　fracture　energy　and　unstable　fracture　toughness　of　SFRC　significantly　increase　with　the　increase　of　fiber　volume　fraction　and　the　decrease　of　temperature.　The　characteristic　length　of　SFRC　decreases　with　decreasing　temper-ature　but　increases　with　increasing　fiber　volume　fraction.　The　initial　fracture　toughness　is　less　affected　by　fiber　content　while　increasing　with　decreasing　temperature.　The　prediction　formulas　were　proposed　which　could　be　used　to　predict　the　fracture　energy,　characteristic　length　and　unstable　fracture　toughness　of　SFRC　at　low　tem-perature,　respectively.
