In　order　to　investigate　the　eccentric　compressive　behavior　of　high-strength　concrete　columns　with　HRB600　steel　bars　to　promote　their　engineering　application,　nine　high-strength　concrete　columns　with　cross-section　dimensions　of　600　mm×600　mm　were　tested　under　monotonic　compression;　the　strength　grades　of　concrete　in　the　columns　were　C60-C100.　HRB600　steel　bars　were　used　as　longitudinal　bars　of　seven　of　the　nine　columns,　while　HRB400　steel　bars　were　used　for　the　other　two　columns.　The　influence　of　design　parameters　such　as　the　strength　of　steel　bars,　concrete　strength,　volume　ratio　of　stirrups　and　load　eccentricity　on　the　eccentric　compressive　behavior　of　high-strength　concrete　columns　was　discussed.　The　results　show　that　the　failure　characteristics,　deflection　curve　and　cross-sectional　strain　distributions　of　high-strength　concrete　columns　with　HRB600　steel　bars　are　basically　the　same　as　those　of　high-strength　concrete　column　with　HRB400　steel　bars.　Under　the　large　eccentric　compression　condition,　the　compressive　bearing　capacity　of　high-strength　concrete　columns　with　HRB600　steel　bars　is　8.55%　higher　than　that　of　HRB400　steel　reinforced　concrete　columns,　and　the　load　decreases　gradually　after　the　peak.　With　the　increase　of　concrete　strength　grade,　volume　ratio　of　stirrups　and　stirrup　strength　grade,　the　compressive　bearing　capacity　of　high-strength　concrete　columns　with　HRB600　steel　bars　increases.　It　is　reliable　to　use　the　relevant　formulae　in　the　current　concrete　structure　design　codes　to　calculate　the　compression-bending　capacity,　the　average　crack　spacing　and　the　maximum　crack　width　of　high-strength　concrete　columns　with　HRB600　steel　bars.　©　2019,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
