This　paper　presents　a　numerical　study　to　evaluate　the　behavior　of　reinforced　concrete　(RC)　columns　with　circular　section　repaired　and　retrofitted　by　high-performance　fiber-reinforced　cement　composites　(HPFRCC)　jackets　and　external　carbon　fiber-reinforced　polymer　(CFRP)　wrapping.　The　column　damage　is　due　to　degradation　of　concrete　and　steel　rebars　for　effect　of　the　corrosion.　Different　HPFRCC　mix　designs　were　considered　to　repair　the　column　assuming　different　fiber　types　(polyethylene,　stainless　steel)　and　volume　contents　(1%　or　2%).　These　HPFRCC　concretes　were　developed　and　tested　experimentally　at　the　lab　of　the　University　of　Roma　Tre　(Salvador　Filho　et　al.　in　Mechanical　properties　of　HPFRCC　reinforced　with　different　types　and　volumes　of　fibres　[1]).　The　numerical　analyses　were　conducted　by　means　of　fiber　models　using　the　software　OpenSees　(OpenSees　structural　software　[computer　software].　Pacific　Earthquake　Engineering　Research　Center,　University　of　California,　Berkeley,　CA,　[2])　applying　a　vertical　load　and　a　displacement　history　(section　rotation).　The　analyzed　sections　represent　the　undamaged　section,　the　section　damaged　for　effect　of　rebar　corrosion,　and　the　repaired　and　retrofitted　sections.　The　first　numerical　results　about　the　section　strength　capacities　for　each　type　of　repair　material　are　discussed.　©　Springer　Nature　Singapore　Pte　Ltd.　2019.
