This　article　investigates　the　axial　compressive　performance　of　concrete-filled　double　steel　tubular　(CFDST)　short　columns　composed　of　circular　section　loaded　concentrically.　An　experimental　program　comprised　of　compression　tests　on　short　columns　is　carried　out　to　examine　their　structural　performance.　Axial　compression　tests　on　conventional　concrete-filled　steel　tubular　(CFST)　columns　and　double-skin　concrete-filled　steel　tubular　(DCFST)　columns　are　also　performed　for　comparison　purposes.　The　test　parameters　include　the　diameter-to-thickness　of　the　outer　and　inner　steel　tubes,　concrete　strength,　and　diameter　ratio.　The　test　results　exhibit　that　CFDST　short　columns　composed　of　the　circular　section　have　improved　structural　performance　compared　to　its　CFST　and　DCFST　counterparts.　A　theoretical　model　is　also　presented　to　simulate　the　test　ultimate　strengths　and　load-axial　strain　relationships　of　CFDST　columns.　The　existing　design　models　proposed　including　the　codified　design　specifications　are　evaluated　against　the　collected　test　data　for　predicting　the　axial　compressive　strengths　of　circular　CFDST　columns.　It　is　seen　that　the　existing　codified　design　models　cannot　yield　their　ultimate　axial　compressive　strengths　accurately.　A　practical　artificial　neural　network　(ANN)　model　is　proposed　to　estimate　the　ultimate　load　of　such　columns　loaded　concentrically.
