A　new　strategy　that　repairs　severely　damaged　reinforced　concrete　(RC)　columns　after　an　earthquake　is　proposed　as　a　simpler　and　quicker　solution　with　respect　to　the　strategies　currently　available　in　the　literature.　The　external　concrete　parts　are　removed　from　the　column　surface　along　the　whole　plastic　hinge　region　to　uncover　the　steel　reinforcement.　The　transverse　steel　is　cut　away,　and　each　longitudinal　rebar　is　locally　substituted　by　steel　rebar　segments　connected　by　welding　connections　to　the　original　undamaged　rebar　pieces　outside　the　intervention　zone.　The　new　rebar　segments　have　a　reduced　diameter　achieved　by　turning　to　ensure　plastic　deformation　only　in　the　plastic　hinge,　protecting　the　original　rebar　and　the　welding　connections.　The　connection　is　specifically　designed　to　be　effective　and　simple,　and　is　directly　realized　on　column　reinforcement.　Finally,　the　removed　concrete　is　restored　by　a　jacket　built　with　high-performance　concrete　with　steel　or　polymer　fibers.　The　use　of　concrete　with　high　volume　fraction　of　polymer　fibers　to　repair　the　column　is　investigated　for　the　first　time　in　this　paper.　This　concrete　was　characterized　by　compression　and　flexural　tests　in　the　laboratory　and　its　mechanical　characteristics　were　compared　with　those　of　the　concrete　with　steel　fibers,　which　are　being　increasingly　used　in　construction.　The　repair　strategy　was　applied　to　two　RC　columns　(1:6　scaled　bridge　piers),　tested　by　asymmetric　cyclic　tests.　The　results　show　that　the　column　strength,　stiffness,　and　ductility　were　restored,　and　the　energy　dissipation　capacity　improved.　The　experimental　evidence　was　investigated　by　fiber　models　in　OpenSees.
