Seven　self-compacting　concrete　short　column　specimens　with　500　MPa　reinforced　bars　were　tested　under　eccentric　compression　load　to　investigate　the　mechanical　behaviors　and　the　co-working　performance　between　high-strength　steel　bars　and　self-compacting　concrete.　The　experimental　results　indicate　that　the　500　MPa　steel　bars　can　work　well　with　self-compacting　concrete,　and　the　average　axial　strains　of　the　specimens　basically　agree　with　the　assumption　of　plane　section　under　the　whole　process　of　eccentric　compression　loading.　Finite　element　(FE)　models　for　the　eccentrically　compressed　short　columns　were　built　by　ABAQUS　software,　and　the　FE　models　were　verified　by　the　test　results.　Furthermore,　numerical　analysis　was　carried　out　to　study　the　influence　of　strength　of　self-compacting　concrete,　initial　eccentricity　and　ratio　of　longitudinal　reinforcement.　The　results　show　that　normal　section　bearing　capacities　of　eccentrically　compressed　self-compacting　concrete　short　columns　with　500　MPa　reinforced　bars　can　be　calculated　according　to　the　current　Chinese　code.　Moreover,　the　design　strength　of　500　MPa　steel　bars　are　suggested　as　fsd=　fsd＇=420　MPa,　and　partial　coefficient　of　the　material　is　suggested　as　γs=1.2.　©　2018,　Engineering　Mechanics　Press.　All　right　reserved.
