摘要：

Dynamic　compressive　tests　of　steel　fiber　reinforced　concrete　(SFRC)　specimens　with　different　fiber　content　(1%　and　2%)　at　different　temperature　(20,　200,　400,　600　and　800)were　carried　out　by　using　the　split　Hopkinson　pressure　bar　and　resistance　heating　stove.The　dynamic　stress-strain　curves　at　different　temperature　were　obtained,　and　the　corresponding　dynamic　compressive　strength　and　peak　strain　were　presented.　The　test　results　show　that　SFRC　has　obvious　strain　rate　strengthening　effect　and　temperature　damage　effect.　At　the　different　test　temperature,　the　dynamic　compressive　strength　of　SFRC　increases　with　the　increase　of　strain　rate.　At　the　same　loading　speed,　the　dynamic　compressive　strength　of　SFRC　is　greatly　reduced　with　the　increase　of　test　temperature.Compared　with　normal　concrete,　the　impact　resistance　of　SFRC　is　greatly　improved.　©　2019,　Editorial　Office　of　Journal　of　Vibration　and　Shock.　All　right　reserved.
