In　order　to　study　the　compresion-bending　performance　of　ultra-high-strength　concrete-filled　high-strength　steel　tube　short　columns,　ten　spcimens　subjected　to　different　eccentric　loads　were　carried　out.　The　failure　modes,　load-deflection　curves,　and　load-strain　curves　of　the　short　columns　were　investigated.　The　results　show　that　with　the　increase　of　eccentricity,　the　compressive　failure　characteristics　associated　with　bending　deformation　tend　to　be　less　obvious,　the　bearing　capacity　decreases,　the　plasticity　level　at　the　edge　of　the　tension　and　compression　zone　increases,　and　the　ductility　is　improved　more　significantly.　Before　the　ultra-high-strength　concrete-filled　high-strength　steel　tube　short　column　reaches　the　eccentric　bearing　capacity,　the　composite　section　satisfies　the　plane　section　assumption.　When　the　eccentricity　is　less　than　1.6,　small　eccentric　failure　occurs　in　ultra-high-strength　concrete-filled　high-strength　steel　tube.　With　the　development　of　section　plasticity,　the　hoop　effect　of　high-strength　steel　tube　on　UHSC　at　the　edge　of　the　compression　zone　is　brought　into　play.　By　comparing　the　bearing　capacity　obtained　from　the　test　and　the　predicted　values　of　GB　50936-2014　＇Technical　code　for　concrete　steel　tubular　structures＇,　it　is　found　that　the　reduction　coefficient　considering　the　influence　of　eccentricity　on　bearing　capacity　is　not　applicable　to　ultra-high-strength　concrete-filled　high-strength　steel　tube　short　column　occurred　in　small　eccentric　failure.　Therefore,　a　modified　calculation　method　of　reduction　coefficient　was　proposed　based　on　the　test　results.　©　2021,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
