This　paper　reports　nine　test　results　of　concrete　filled　steel　tube　reinforced　concrete　(CFSTRC)　columns,　which　were　tested　under　constant　axial　load　and　cyclically　increasing　flexural　loading.　The　main　parameters　varied　in　the　experiments　were　axial　load　level　and　cross-sectional　type.　The　influence　of　these　parameters　on　strength,　ductility,　stiffness　and　energy　dissipation　was　investigated.　It　was　found　that,　in　general,　CFSTRC　columns　exhibit　favourable　energy　dissipation　and　ductility,　even　when　the　columns　were　subjected　to　high　axial　loads.　This　type　of　composite　column　is　adoptable　in　practical　engineering,　particularly　in　regions　of　high　seismicity.　(C)　2009　Elsevier　Ltd.　All　rights　reserved.
