This　paper　presents　the　results　of　tests　conducted　on　ten　ultra-high-strength　concrete-filled　steel　tube　(CuFShT)　short　columns　subjected　to　different　eccentric　loads.　The　study　investigated　failure　modes,　load-deflection　curves,　and　load-strain　curves　of　these　short　columns.　The　findings　reveal　that　the　bearing　capacity　decreases　while　ductility　significantly　improves　with　increasing　eccentricity.　Before　reaching　its　eccentric　bearing　capacity,　the　CuFShT　short　column　satisfies　the　flat　section　assumption.　As　section　plasticity　develops,　the　hoop　effect　of　the　high-strength　steel　tube　on　ultra-high-strength　concrete　at　the　edge　of　the　compression　zone　comes　into　play.　Through　a　comparison　between　the　tested　bearing　capacity　and　the　predicted　values　from　the　Chinese　code,　a　modified　reduction　coefficient　is　proposed.
