The　present　paper　is　an　attempt　to　study　the　cyclic　behaviours　of　self-consolidating　concrete　(SCC)　filled　hollow　structural　steel　(HSS)　columns.　The　test　parameters　include　the　sectional　types,　the　strength　of　concrete　and　steel　and　the　axial　load　level　(n).　Eighteen　self-consolidating　concrete　filled　hollow　structural　steel　(SCCHSS)　column　specimens,　including　10　specimens　with　circular　sections　and　8　specimens　with　square　sections　were　tested　under　constant　axial　load　and　cyclically　increasing　flexural　loading.　It　was　found　that,　in　general,　SCCHSS　columns　exhibit　very　high　levels　of　energy　dissipation　and　ductility,　particularly　when　subjected　to　high　axial　loads.　The　features　of　SCCHSS　columns　under　constant　axial　load　and　cyclically　increasing　flexural　loading　are　similar　to　those　of　normal　concrete-filled　HSS　columns.　Comparisons　are　made　with　predicted　column　strengths　and　flexural　stiffness　using　the　existing　codes　such　as　AIJ-1997,　AISC-LRFD-1994,　BS5400-1979　and　EC4-1994.
