Circular　hollow　centrifugal　concrete-filled　steel　tubes　(HCCFSTs)　are　employed　widely　as　structural　components,　such　as　power　station　structures　and　building　foundations,　in　virtue　of　their　exceedingly　good　structural　performance　features.　It　is　essential　to　comprehend　the　compressive　behavior　of　circular　HCCFST　columns　and　suitably　evaluate　their　compressive　strength　for　practical　engineering　design.　However,　limited　researches　on　HCCFST　columns　have　almost　not　resulted　in　the　development　of　appropriate　design　formulae　in　current　international　standards.　This　paper　aims　to　propose　a　practical　formula　for　estimating　the　compressive　strength　of　circular　HCCFST　stub　columns　that　have　a　wide　range　of　parameters.　A　new　confinement　coefficient　reflecting　the　confinement　effect　of　concrete　strength　in　circular　HCCFST　short　columns　is　proposed,　and　using　the　proposed　confinement　coefficient,　a　novel　strength　design　formula　is　developed　to　estimate　the　compressive　strength　of　circular　HCCFST　short　columns.　The　proposed　formula　is　investigated　using　collected　experimental　data　from　literature　and　finite　element　analysis　results.　It　is　shown　that　the　proposed　confinement　coefficient　can　reflect　the　interaction　effect　between　the　steel　tube　and　infilled　concrete,　and　the　developed　axial　capacity　formula　in　this　paper　offers　better　predictions　of　compressive　strength　than　current　design　formulae.
