To　explore　the　mechanical　behavior　of　SFRC　beams　subjected　to　both　impact　and　fire　loadings,　4　beams　were　tested　with　high-performance　drop-weight　test　system,　four　point　bending　test　machine　and　assembled　electric　furnace.　The　beams　were　firstly　subjected　to　impact　loadings　and　then　exposed　to　fire　with　a　constant　load.　During　the　test　process,　the　crack　patterns　of　beams　were　observed　while　the　time　histories　of　mid-span　deflections　and　rebar　strain　were　recorded.　Then,　the　fire　resistance　of　these　beams　was　discussed.　Based　on　the　experiment,　three-dimensional　macroscopic　finite　element　numerical　model　considering　the　effects　of　strain　rate　and　high　temperature　was　established.　The　impact　loading　process　was　simulated　firstly;　and　then　taking　simulation　results　as　the　initial　state,　SFRC　beams　subjected　to　both　fire　and　constant　loading　were　simulated　with　a　sequentially　coupled　thermal-stress　analysis　method.　Moreover,　considering　the　heterogeneity　of　concrete＇s　internal　structure,　a　meso-scale　simulation　was　also　conducted　with　the　procedures　similar　to　that　in　macroscopic　simulation.　Good　agreement　between　both　the　macro-/meso-scale　simulation　results　and　the　test　results　illustrates　the　rationality　and　effectiveness　of　the　present　numerical　analysis　methods.　The　advantages　of　mesoscopic　model　were　indicated　through　the　comparison　of　macro-/meso-scopic　results.　It　has　been　found　that　when　the　impact　energy　is　low,　the　local　concrete　is　cracked　but　a　small　overall　deformation　is　remained.　Nevertheless,　this　degrades　the　fire　resistance　of　SFRC　beams　to　some　ex-tent.　When　the　steel　fiber　dosage　increases,　resulting　in　an　increasing　shear　strength　of　concrete　matrix,　the　coexistence　phenomenon　of　bending　and　shear　cracks　of　beams　under　the　impact　load　is　changed　to　bending　cracks　as　a　dominant.　Moreover,　when　subjected　to　elevated　temperatures　with　a　constant　load,　the　distribution　of　cracks　on　the　impact-damaged　SFRC　beams　is　relatively　concentrated　and　a　brittle　failure　occurs.　©　2019,　Editorial　Staff　of　EXPLOSION　AND　SHOCK　WAVES.　All　right　reserved.
