Five　Concrete　Filled　Steel　Tubular　(CFST)　laced　columns　and　two　steel　tube　laced　columns　subjected　to　eccentrically　loads　were　tested　with　of　eccentricities.　Test　results　indicate　that　the　ultimate　load　carrying　capability　of　laced　columns　decreases　with　the　increase　of　eccentricity.　Longitudinal　elements　in　the　loading　side　of　all　specimens　are　subjected　to　eccentrically　forces　with　small　eccentricity　during　the　whole　process,　while　those　away　from　the　load　are　subjected　to　forces　from　small　eccentricity　to　large　eccentricity　with　the　increase　of　whole　eccentricity　of　the　columns.　The　ultimate　load-carrying　capacity,　stiffness　and　deformation　capability　of　CFST　specimens　are　all　larger　than　those　of　hollow　steel　tubes.　The　influence　of　eccentricity　to　ultimate　load-carrying　capacity　of　CFST　laced　columns　is　analyzed.　Finally,　calculation　methods　in　design　criteria　for　CFST　structures　are　discussed.
