A　finite　element　analysis　method　is　proposed　for　Concrete-Filled　Steel　Tubular　(CFST)　lattice　columns.　Calculation　results　from　using　the　ANSYS　software　agree　well　with　the　test　results.　The　influences　of　eccentricity,　slenderness　ratio　and　constructional　parameter　on　the　ultimate　load　carrying　capacity　are　analyzed.　Calculation　results　from　three　design　criteria　for　CFST　structures　in　China　(CECS　28:90,　JCJ　01-89,　DL/T　5085-1999)　are　compared　with　those　from　FEM　analysis.　The　results　indicate　that　the　calculation　method　for　eccentricity　reduction　factor　in　CECS　28:90　is　reasonable.　Steel　type　and　concrete　strength　of　longitudinal　elements　greatly　influence　the　stability　factor.　A　calculation　method　for　material　modification　coefficient　is　presented　in　the　calculation　of　equivalent　slenderness　ratio.　Constructional　parameters,　for　example,　angles　of　diagonal　lacing　tubes,　have　little　influence　on　the　ultimate　load　carrying　capacity　of　CFST　laced　columns,　which　attests　to　the　rationality　of　the　simplified　enlarging　parameter　method　for　calculating　the　equivalent　slenderness　ratio.　Suggestions　are　provided　for　modifying　the　equivalent　slenderness　ratio　in　the　three　China　design　criteria　on　CFST　structures.　A　rational　method　for　calculating　the　ultimate　load　carrying　capacity　of　four-element　CFST　laced　columns　is　also　presented.
