To　investigate　the　axial-flexural　behavior　of　high　strength　concrete　columns　made　of　recycled　coarse　aggregate,　this　paper　presents　a　repeated　large　eccentric　loading　test　on　four　large　size　reinforced　concrete　columns.　Two　kinds　of　cross-section　columns　were　included,　one　is　square　cross　section　with　the　size　of　600mm　×　600mm,　the　other　is　circular　cross　section　with　the　diameter　of　675　mm.　The　variable　parameter　is　the　replacement　ratio　of　recycled　coarse　aggregate.　Based　on　the　test,　the　failure　characteristics,　load-bearing　capacity,　stiffness　and　the　regularities　of　development　for　section　strain　were　analyzed.　Results　show　that　the　difference　about　failure　process,　failure　modes,　degradation　of　stiffness　and　the　regularities　of　development　for　section　strain　between　recycled　concrete　columns　and　normal　concrete　columns　are　not　obvious.　The　ultimate　load-bearing　capacity　of　recycled　coarse　aggregate　columns　were　calculated　by　the　related　calculating　formula　in　the　code　for　design　of　normal　concrete　structures.　The　calculated　results　agree　well　with　the　measured　results.　It　is　indicated　that　the　calculated　accuracy　can　meet　the　engineering　requirements.
