In　order　to　promote　the　application　of　recycled　concrete　in　structural　members,　the　effect　of　recycled　coarse　aggregate　(RCA)　replacement　ratio　and　inner　steel　on　seismic　performance　of　high-strength　recycled　concrete　columns　under　high　axial　compression　ratio　was　investigated.　Low　frequency　cyclic　loading　tests　on　6　column　specimens,　including　3　steel　reinforced　recycled　concrete　(SRRC)　columns　and　3　reinforced　recycled　concrete　(RRC)　columns,　with　a　600　mm　x　600　mm　cross　section　were　carried　out.　Results　show　that　high-strength　RRC　columns　under　high　axial　compression　ratio　have　reliable　seismic　performance.　The　seismic　performance　of　RRC　columns　is　improved　by　adding　inner　steel,　especially　for　specimens　with　high　RCA　replacement　ratio.　The　replacement　ratio　of　RCA　has　no　obvious　effect　on　SRRC　column　bearing　capacity　and　ductility,　but　for　RRC　columns,　it　slightly　reduces　bearing　capacity　and　energy　consumption.　When　the　specimen　is　damaged,　the　reinforcement　and　flange　section　in　the　compression　zone　yields,　while　the　reinforcement　in　the　tension　zone　approaches　yielding.　According　to　the　plane　assumption　and　considering　the　confining　effect　for　the　concrete　provided　by　stirrup　and　steel,　the　crack　load,　yield　load,　and　peak　load　are　calculated,　and　calculated　values　are　in　good　agreement　with　experimental　values.　This　study　provides　a　reference　for　the　application　of　high-strength　recycled　concrete　columns　in　practical　engineering.
