Based　on　the　trial　design　of　composite　arch　bridge　with　steel　webs　and　skeleton　reinforced　concrete(SRC)　flanges,　the　research　on　compression　performance　of　9　specimens　were　carried　out　for　the　composite　column　with　SRC　by　changing　the　parameters　of　diameter-thickness　ratio　and　eccentricity　ratio.　The　results　show　that　most　columns　were　wrecked　by　crushing　the　concrete　outside　the　steel　tube,　and　the　net　crack　distribution　was　dominant.　The　concrete　far　away　from　the　load　was　tensioned　for　eccentric　compression　members.　The　outside　concrete,　steel　tube　and　longitudinal　reinforcement　of　composite　column　with　SRC　work　cooperatively　under　compression.　The　greater　the　eccentricity　ratio,　the　lower　the　bearing　capacity　and　stiffness　of　compressive　members.　The　influence　of　diameter-thickness　ratio　on　bearing　capacity　was　smaller　under　the　axial　compression.　While　for　eccentric　compression　members,　the　capacity　reached　to　extreme　when　the　diameter-thickness　ratio　was　0.5.
