This　paper　is　an　attempt　to　study　the　cyclic　performances　of　recycled　aggregate　concrete　(RAC)-filled　steel　tubular　Columns.　Thirteen　specimens　with　circular　section.　including　10　RAC-filled　steel　tubular　(RACFST)　columns　and　3　reference　normal　concrete-filled　steel　tubular　(CFST)　columns.　were　tested　under　constant　axial　load　and　cyclically　increasing　flexural　loadings.　The　parameters　in　the　test　are:　(1)　concrete　type:　normal　concrete　and　recycled　aggregate　concrete:　and　(2)　axial　load　ratio　(n),　from　0.05　to　0.52.　It　was　found　that.　generally,　the　performances　of　RACFST　columns　under　constant　axial　load　and　cyclically　increasing　flexural　loadings　are　similar　to　the　corresponding　normal　CFST　columns,　and　RACFST　columns　can　also　exhibit　high　ductility　levels　and　energy　dissipation　abilities.
