Reinforced　concrete　(RC)　bridge　piers　damaged　after　a　strong　earthquake　are　repaired.　The　damaged　concrete　and　the　steel　reinforcement　parts　are　replaced　by　rebar　segments　connected　to　the　existing　rebar　parts　by　welding　connections　and　by　a　self-compacting　concrete　jacket　respectively.　A　modest　transverse　steel　reinforcement,　not　sufficient　to　improve　the　seismic　pier　capacity,　is　used　to　simplifies　the　concrete　cast　in　modest　volumes.　After　the　repair,　a　carbon　fiber　reinforced　polymer　(Carbon　FRP)　reinforcement　is　applied　to　enhance　the　pier　ductility　and　the　shear　strength.　Three　RC　circular　columns,　representative　of　piers,　were　repaired　and　reinforced　by　the　proposed　strategy　to　be　tested　in　lab　applying　a　deformation　history　due　to　a　strong　earthquake.　The　piers　were　able　to　sustain　very　strong　seismic　demand　and　therefore　the　proposed　repair　and　retrofitting　interventions　are　effective.　The　strain　distribution　of　the　Carbon　FRP　reinforcement　was　measured　and　discussed　to　increase　the　very　modest　database　presented　in　the　literature.
