Abstract：

This　paper　presents　an　experimental　investigation　on　circular　concrete-filled　double　steel　tubular　(CFDST)　slender　columns　under　axial　loading.　The　test　parameters　include　the　column　slenderness　ratio　and　the　thickness　of　the　inner　steel　tube.　Test　results　show　that　the　common　failure　mode　of　CFDST　slender　columns　is　the　global　failure　of　the　columns.　It　is　found　that　increasing　the　column　slenderness　decreases　the　ultimate　strengths　of　the　columns　and　the　thickness　of　the　inner　steel　has　an　insignificant　influence　on　the　ultimate　strength　of　the　columns.　The　design　model　specified　by　Eurocode　4　for　conventional　CFST　slender　columns　is　shown　to　overestimate　the　ultimate　strength　of　CFDST　slender　columns　under　axial　loading.　©　2022,　Avestia　Publishing.　All　rights　reserved.
