Except　for　service　loadings,　concrete　or　steel　fiber　reinforced　concrete　(SFRC)　may　be　subjected　to　some　extreme　loadings,　such　as　fire,　impact,　blast　or　their　combinations　during　occasional　events.　In　order　to　capture　the　mechanical　behavior　of　SFRC　subjected　to　both　high　temperature　and　high　strain　rate,　three　SFRC　mixtures　with　different　steel　fiber　volume　fractions　were　experimentally　tested　using　both　resistance　furnace　and　SHPB　apparatus.　The　exposure　temperatures　included　25　degrees　C,　200　degrees　C,　400　degrees　C,　600　degrees　C　and　800　degrees　C,　while　the　strain　rate　range　was　from　36　s(-1)　to　185　s(-1).　For　the　comparison　purpose,　quasi-static　tests　were　carried　out　at　corresponding　temperatures.　The　results　indicate　that　under　temperatures　no　higher　than　600　degrees　C,　the　addition　of　steel　fiber　can　effectively　inhibit　SFRC　specimens　from　crushing　into　fragments　when　subjected　to　dynamic　compressive　loadings.　Both　quasi-static　and　dynamic　stress-strain　curves　have　similar　shapes,　and　they　become　flatter　and　flatter　with　respect　to　temperature.　Under　elevated　temperatures,　dynamic　compressive　strength　of　SFRC　still　displays　obvious　strain　rate　sensitivity.　The　exposure　to　high　temperature　reduces　strength　and　elastic　modulus　of　SFRC　while　increases　its　critical　strain.　Peak　toughness　increases　firstly　and　then　decreases　with　increasing　the　temperature.　The　amount　of　steel　fiber　has　a　quite　slight　effect　on　strength,　critical　strain,　elastic　modulus　and　toughness　of　SFRC　in　high　temperature　conditions.　(C)　2019　Elsevier　Ltd.　All　rights　reserved.
