A　three-dimensional　numerical　model　was　established　to　investigate　the　impact　resistance　of　concrete　shear　walls　reinforced　with　fiber-reinforced　polymer　(FRP)　bars,　considering　the　strain　rate　effect　of　FRP　reinforcement　and　concrete　materials.　After　validating　the　numerical　model,　the　failure　mechanism　of　concrete　shear　walls　reinforced　with　glass　fiber-reinforced　polymer　(GFRP)　bars　under　impact　load　was　studied.　The　influence　of　impact　velocity　and　axial　load　ratio　on　the　impact　resistance　of　GFRP-reinforced　concrete　shear　walls　was　discussed.　The　results　showed　that　GFRP-reinforced　concrete　walls　have　similar　behavior　to　conventional　reinforced　concrete　walls　under　impact　loadings.　The　former　experienced　more　considerable　deformation　due　to　the　lower　elastic　modulus　of　GFRP　bars.　The　peak　and　residual　displacement　at　the　center　of　the　wall　increased　linearly　with　the　impact　energy.　In　addition,　the　peak　value,　plateau　value,　impulse,　and　duration　of　impact　force　grew　linearly　with　respect　to　impact　velocity.　The　proportion　of　energy　absorbed　by　concrete　increased　in　the　cases　of　larger　impact　velocity.　From　the　perspective　of　the　internal　force　envelope　along　the　wall　height,　the　dangerous　sections　under　impact　were　located　at　both　ends　of　the　wall　under　axial　load.　The　peak　value　of　the　internal　force　improved　with　an　increase　of　the　axial　load　ratio.　When　the　axial　load　ratio　was　between　0.3　and　0.4,　the　impact　force　of　the　wall　reached　the　largest,　and　the　minimum　deformation　occurs,　indicating　the　best　impact　resistance　of　the　shear　walls.　As　the　axial　load　ratio　increased　from　0.1　to　0.5,　the　total　energy　consumption　increased　from　68%　to　89%,　among　which　the　external　force　work　is　57　times　that　of　the　0.1　axial　load　ratio,　aggravating　the　failure　of　walls.
