In　order　to　expand　the　application　of　high-strength　recycled　concrete,　five　full-scale　square　high-strength　recycled　concrete　columns　(600　x　600　mm)　were　tested　under　the　experimental　axial　compression　ratio　(ACR)　of　0.54.　The　seismic　behavior　of　reinforced　high-strength　recycled　aggregate　concrete　columns　under　high　ACR　and　the　effects　of　recycled　coarse　aggregate　(RCA)　replacement　ratio　and　ACR　on　the　seismic　behavior　were　analyzed.　The　results　showed　that　the　high-strength　recycled　concrete　columns　have　potential　to　collapse-resistance　capacity　subjected　to　strong　earthquakes.　Under　the　similar　concrete　strengths,　the　mechanical　properties　of　high-strength　recycled　aggregate　concrete　columns　and　ordinary　concrete　columns　were　comparable　even　under　high　ACR.　As　the　ACR　increased　from　0.35　to　0.54,　the　bearing　capacity　increased　by　up　to　12.6%,　while　the　ductility　decreased　by　up　to　32.8%.　The　specimens　with　100%　RCA　were　more　sensitive　to　ACR　than　those　with　50%　RCA.　A　four-fold　restoring　force　model　considering　the　effects　of　axial　load,　reinforcement　ratio,　shear　span,　and　RCA　replacement　ratio　was　established,　which　was　in　good　agreement　with　the　experimental　curves.
