In　order　to　reveal　the　mechanical　behavior　of　recycled　aggregate　concrete-filled　circle　steel　tube　column　under　axial　compression　loading.　22　specimens　were　designed　for　test.　The　specimens　parameters　are　recycled　coarse　aggregate　replacement　percentage　and　steel　confine　coefficient.　According　to　the　test,　the　failure　process　and　patterns　were　obtained,　the　whole　process　curve　of　stress-　strain　and　secant　modulus-stress　were　measured,　and　some　important　parameters,　such　as　the　peak　stress　and　peak　strain　were　analyzed,　the　study　indicates　that　the　recycled　aggregate　concrete-filled　circular　steel　tube　columns＇　failure　patterns　are　similar　to　ordinary　concrete-filled　steel　tube　column.　With　the　recycled　coarse　aggregate　replacement　percentage　increasing,　the　peak　stress　has　slightly　increased.　In　the　end,　the　bearing　capacity　calculation　method　is　discussed.　©2010　IEEE.
