This　paper　describes　an　experimental　study　on　the　behavior　of　lateral　impact-damaged　short　columns　and　then　reinforced　with　carbon　fiber　reinforced　polymer　(CFRP).　The　purpose　of　the　study　was　to　evaluate　the　reinforcement　effect　of　wrapping　CFRP　sheet　on　steel　short　columns　with　lateral　impact　damage.　In　this　experimental　study,　thirty-three　short　columns　were　tested　to　study　the　influence　of　the　impact　energy,　the　loading　position　and　the　layer　number　of　CFRP　sheets　on　the　ultimate　strength　of　tested　specimens.　The　ultimate　strength,　initial　stiffness,　ductility　and　failure　modes　of　specimens　were　presented.　The　test　results　show　that　ultimate　strength　of　columns　has　negative　relation　with　lateral　impact　energy.　The　results　also　show　that　the　closer　impact　position　approaches　to　the　end　of　specimens,　the　more　decrease　of　ultimate　strength　shows.　Wrapping　CFRP　sheets　could　improve　the　ultimate　strength　of　specimens　and　delay　local　buckling.　Based　on　the　analysis　of　the　experimental　data,　simplified　formulas　were　put　forward　to　predict　the　ultimate　strength　of　the　tested　specimens,　which　show　a　good　agreement　with　the　experimental　results.　©　2018　Elsevier　Ltd
