Large　rupture　strain　(LRS)　fiber-reinforced　polymers　(FRP)　composites　with　an　elongation　greater　than　5%　offer　an　attractive　solution　for　seismic　strengthening　of　reinforced　concrete　(RC)　columns.　For　a　quick　and　reliable　design　of　LRS　FRP-strengthened　RC　columns,　this　paper　presents　a　simplified　plasticity　damage　model　for　LRS　FRP-confined　concrete　under　cyclic　axial　compression.　This　model　consists　of　two　parts:　(a)　a　recent　monotonic　LRS　FRP-confined　concrete　model　developed　by　the　authors’　group　as　an　envelope　curve　and　(b)　a　simplified　linear　plasticity　damage　cyclic　rule　for　predicting　unloading　and　reloading　paths.　To　solve　the　cyclic　model　deviation　induced　by　concrete　softening　under　a　large　axial　strain,　a　pseudo-plastic　strain　was　proposed,　based　on　which　the　damage　degradation　of　FRP-confined　concrete　can　be　quantified.　The　model　comparisons　show　that　although　the　proposed　model　sacrificed　some　precision　when　directly　applied　for　the　cyclic　axial　compressive　behavior　of　FRP-confined　concrete,　it　can　give　similarly　accurate　predictions　as　a　complex　model　does　for　the　behavior　of　conventional　or　LRS　FRP-jacketed　RC　columns　under　a　combined　axial　load　and　cyclic　lateral　load.　Thus,　this　simplified　plasticity　damage　model　serves　as　a　promising　basic　model　for　simulation　of　the　seismic　performance　of　FRP-strengthened　structures.　©　2021　Elsevier　Ltd
