Twenty-four　concrete　filled　steel　tubular　(CFST)　battened　column　specimens　were　tested.　Parameters　of　column　slenderness,　load　eccentricity,　chord　spacing　and　batten　spacing　were　investigated　in　the　experimental　research.　The　whole　load-bearing　process,　the　failure　modes　and　ultimate　load-carrying　capacities　of　the　specimens　were　analyzed.　Nonlinear　finite　element　models　were　established　on　the　environment　of　software　ANSYS　to　simulate　the　whole　behaviors　of　the　specimens　during　the　test　process.　Using　the　conformed　FEM,　extensive　parametric　study　was　conduced　and　ultimate　load-carrying　capacity　of　the　specimens　calculated　by　FEM　and　estimated　by　China　specifications　of　CFST　structures　were　compared　to　the　tested　results.　Finally,　some　suggestions　were　presented　for　simplified　calculation　of　the　ultimate　load　carrying　capacity　of　CFST　battened　columns.
