Tests　of　24　concrete-filled　steel　tubular　(CFST)　battened　columns　were　carried　out.　The　experimental　parameters　were　column　slenderness,　load　eccentricity,　chord　spacing　and　batten　spacing.　The　whole　load-carrying　process,　failure　modes　and　ultimate　load-carrying　capacities　of　the　specimens　were　analyzed　in　this　paper.　The　mechanical　behaviors　of　batten　members　and　their　effects　on　ultimate　load-carrying　capacities　of　the　specimens　were　discussed　in　detail.　Test　results　show　that,　bending　moment　is　dominate　force　in　battens　of　the　specimens　unlike　axial　force　in　lacing　bars　in　the　laced　column,　and　strains　of　battens　are　much　larger　than　those　of　lacing　bars.　Chord　spacing　and　batten　spacing　of　batten　column　affect　load-carrying　capacity　obviously.　With　the　increase　of　slenderness　the　column　behavior　shifts　towards　slender　column　from　stub　column.　Eccentricity　and　slenderness　are　parameters　affecting　the　load-carrying　capacities　of　CFST　battened　column　independently　which　can　be　used　as　subentry-parameter　multiplication　formula　for　the　corresponding　effect　both.　The　stability　coefficient　and　eccentricity　reduction　coefficient　of　CFST　battened　column　are　adopted　by　the　same　method　of　laced　column,　but　the　effect　on　load-carrying　capacities　for　deformation　in　shear　is　greater　than　the　latter.　A　calculation　method　for　equivalent　slenderness　ratio　by　a　graphical　method　is　presented.
