An　appropriate　hybrid　form　of　steel　and　fiber-reinforced　polymer　(FRP)　bars　in　reinforced　concrete　members　can　prevent　steel　corrosion　and　ensure　capacity　and　ductility.　To　investigate　the　impact　resistance　of　concrete　beams　reinforced　with　hybrid　steel　and　basalt　FRP　(BFRP)　bars,　a　three-dimensional　numerical　model　was　developed　that　takes　into　account　the　strain-rate　strengthening　effect.　The　validity　of　the　numerical　model　was　first　verified.　Subsequently,　drop　hammer　impacts　were　simulated　on　10　concrete　beams　reinforced　with　hybrid　steel-BFRP　bars　to　determine　the　influence　of　the　BFRP　bar　proportion　and　position　on　their　impact　resistance.　The　results　indicated　that　the　level　of　concrete　damage　in　the　hybrid　bar-RC　beams　is　between　those　of　the　concrete　beams　with　steel　bars　and　concrete　beams　with　BFRP　bars.　As　the　proportion　of　BFRP　bars　increased　from　0　to　1,　the　peak　impact　force　and　internal　force　of　the　beams　linearly　decreased　by　20%,　the　reaction　force　linearly　declined　by　50%,　while　the　peak　midspan　displacement　linearly　increased　by　20%.　Except　for　the　midspan　deflection,　the　comparable　degree　of　damage　among　beams　with　four　different　bar　configurations　indicates　the　equivalent　impact　resistance　of　the　beams.　The　change　in　the　frequency　of　the　hybrid　bar-RC　beams　before　and　after　impact　loading　can　reflect　their　impact　resistance.　©　2023　American　Society　of　Civil　Engineers.
