Axial　compression　experiments　of　four　full-scale　reinforced　concrete　columns　of　two　groups　were　carried　out.　One　group　of　three　columns　used　high-strength　steel　with　the　yield　strength　of　1000MPa　as　reinforcement　hoops,　and　the　second　group　used　the　ordinary-strength　steel　with　yield　strength　of　400MPa.　The　axial　compressive　performances　between　these　two　groups　were　assessed.　Compared　to　the　specimen　using　the　ordinary-strength　steel,　the　axial　compressive　bearing　capacity　of　using　the　high　strength　steel　dose　not　increase　significantly,　while　the　deformation　ability　increases　greatly.　The　results　also　indicate　that　the　stress　redistributions　of　the　hoops　and　the　concrete　sections　are　obvious,　and　long-lasting　when　specimens　achieve　the　ultimate　bearing　capacity　after　the　yield　of　the　rebar　and　local　damage　of　concrete　materials,　at　this　time　the　strain　of　the　specimens　develops　a　lot,　especially　stress　-　strain　curves　of　specimens　with　high-strength　hoop　all　show　a　wide　and　flat　top.
