As　a　kind　of　impact　resistant　material,　steel　fiber　reinforced　concrete　(SFRC)　has　a　good　ductility　and　energy　dissipation　capacity　by　improving　the　tensile　strength　and　impact　toughness.　To　explore　the　dynamic　mechanical　behavior　of　SFRC　beams　subjected　to　impact　loading,　12　simply-supported　SFRC　beams　with　different　stirrup　ratios　(0%,　0.253%　and　0.502%)　and　different　volume　fractions　of　steel　fibers　(0%,　1%,　2%　and　3%)　were　tested　with　free-falling　drop-weights　impacting　at　the　mid-span　of　specimens.　The　failure　patterns　were　observed　and　videoed,　and　simultaneously,　the　time　histories　of　the　impact　force,　the　reaction　force,　and　the　mid-span　deflection　were　recorded.　Moreover,　the　influences　of　stirrup　ratio　and　volume　fraction　of　steel　fibers　on　the　impact　resistant　behavior　of　the　SFRC　beams　were　preliminarily　analyzed　and　discussed.　The　results　indicate　that　the　impact　resistant　performance　of　SFRC　beams,　such　as　crack　pattern,　ductility,　energy　consumption　capacity,　and　deformation　recovery　capacity　can　be　improved　by　the　addition　of　steel　fibers　and　stirrups.　The　required　static　capacity　of　these　beams　were　calculated　based　on　the　analysis　of　reaction　force　vs.　displacement　loop　and　impact　force　vs.　displacement　loop　as　well　as　absorbed　energy　ratio.　For　further　understanding　the　experimental　results,　finite　element　simulation　of　SFRC　beams　subjected　to　impact　loading　were　carried　out.　The　rationality　and　accuracy　of　the　finite　element　model　was　illustrated　by　the　good　agreement　between　the　test　observations　and　the　numerical　results.
