In　order　to　study　the　behavior　of　steel　reinforced　recycled　aggregate　concrete　(SRRAC)　composite　columns　under　axial　compression　loading,　23　specimens　are　designed,　and　three　vary　parameters　are　considered,　which　are　the　recycled　coarse　aggregate　replacement　rate,　the　volumetric　percentage　of　stirrups　and　concrete　strength　grade.　Failure　patterns,　the　curves　of　the　whole　force　process,　and　the　ultimate　bearing　capacity　are　obtained,　and　the　influence　of　three　parameters　is　analyzed.　Based　on　the　experiment,　a　strength　formula　of　SRRAC　columns　is　proposed.　The　results　show　that　the　steel　is　yield,　the　recycled　concrete　is　crushed,　and　the　SRRAC　columns　have　good　bearing　behavior.　Three　parameters　have　a　great　influence　on　the　bearing　capacity,　and　an　optimum　recycled　coarse　aggregate　replacement　rate　is　40%.　The　ultimate　bearing　capacity　of　SRRAC　columns　calculated　according　to　the　proposed　formula　is　coincide　with　the　test　results.　The　results　can　provide　a　reference　for　a　further　research　and　engineering　applications　of　SRRAC　composite　structures.
