Hybrid　steel-BFRP　reinforced　concrete　(HRC)　beams　have　demonstrated　their　ability　to　meet　the　rigorous　demands　for　both　strength　and　serviceability.　However,　the　mechanical　properties　of　HRC　beams　under　fire　accompanied　by　impact　loadings　are　not　yet　clear.　In　order　to　delve　into　the　impact　resistance　of　HRC　beams　under　high　temperatures,　a　three-dimensional　numerical　model　was　crafted　to　account　for　both　the　effects　of　strain　rate　and　temperature　degradation.　The　study　aimed　to　examine　how　the　impact　resistance　of　HRC　beams　is　influenced　by　varying　area　ratios　and　arrangements　of　BFRP　bars.　The　model＇s　reliability　was　ascertained　through　a　comparison　between　its　simulation　outcomes　and　the　results　of　physical　tests.　The　results　show　that　HRC　beams　exhibit　a　significant　reduction　in　stiffness,　impact　and　internal　force　under　fire　conditions　(39　%,　38　%　and　72　%　for　a　fire　duration　of　45　min,　respectively).　Furthermore,　the　damage　is　concentrated　in　the　midspan.　The　impact　performance　of　HRC　beams　at　room　and　high　temperatures　is　between　those　of　pure　steelRC　beams　and　pure-BFRP　beams.　The　variations　under　the　same　fire　conditions　in　the　displacement　and　internal　force　of　beams　with　different　BFRP　bars　area　ratios　reach　70　%,　while　with　different　arrangements　of　BFRP　bars　do　not　differ　much　(within　20　%).　The　dynamic　to　static　stiffness　ratio　and　ultimate　load　ratio　is　reduced　following　the　growth　of　BFRP　bars　area　ratio　(max.　gap　up　to　56　%　and　25　%)　and　fire　time　(max.　gap　up　to　15　%　and　20　%).　Therefore,　specimen　design　prioritizes　the　bar　arrangement　with　better　corrosion　resistance.　Additionally,　the　residual　bearing　capacity　of　HRC　beams　is　only　10-40　%　of　the　original　under　45　min　fire　duration.　The　association　of　residual　load　capacity　and　displacement　with　fire　time　shifted　from　linear　to　nonlinear　with　rising　temperature.
