This　paper　presents　a　series　of　tests　conducted　on　axial　compression　of　concrete-filled　steel　tubes　with　double　inner　circular　steel　tubes　(DIC-CFST)　stub　columns.　The　DIC-CFST　stub　columns　are　composed　of　four　elements:　an　outer　circular　steel　tube,　two　inner　hollow　circular　steel　tubes　arranged　symmetrically　along　the　diameter　of　the　outer　tube,　and　concrete　filling　the　space　between　the　three　steel　tubes.　A　total　of　27　specimens　with　varying　eccentricity　ratio　(e),　hollow　ratio　(psi),　and　concrete　strength　(C)　were　subjected　to　the　tests.　The　results　indicate　that　under　axial　compression,　noticeable　local　buckling　failures　occur　in　both　the　inner　and　outer　steel　tubes.　Concrete　failure　manifests　as　vertical　through　cracks　and　circumferential　crushing　zones.　The　load-deformation　curve　of　the　specimens　remains　essentially　the　same　as　that　of　a　full-section　concrete-filled　steel　tube.　A　general　positive　correlation　exists　between　the　ultimate　bearing　capacity　and　the　strength　of　concrete,　and　the　range　of　eccentricity　ratio　and　hollow　ratio　significantly　influences　the　relationship　between　these　two　parameters　and　the　ultimate　bearing　capacity　of　the　specimens.　As　the　concrete　strength　increases,　the　initial　stiffness　exhibits　a　noticeable　increase.　Conversely,　the　initial　stiffness　experiences　a　significant　reduction　with　an　increase　in　the　hollow　ratio.　The　ductility　decreases　with　increasing　concrete　strength　and　eccentricity　ratio.　Furthermore,　in　comparison　to　the　AISC　360-10　Specification,　Eurocode　4,　and　Han＇s　method,　the　calculation　formula　proposed　in　this　paper　for　determining　the　ultimate　bearing　capacity　of　DIC-CFST　stub　columns　has　exhibited　superior　accuracy.
