To　investigate　the　axial　compressive　behavior　of　reinforced　concrete　columns　with　close　confinement,　a　total　of　seven　full-scale　reinforced　concrete　columns　with　stirrup　characteristic　values　in　the　range　0.22　~0.47　and　section　dimension　600　mm　×　600　mm　were　tested　under　concentric　compression　loading.　The　test　results　indicated　that　all　specimens　failed　in　a　similar　way.　The　longitudinal　bars　were　buckled　in　compression;　the　peripheral　stirrups　were　bowed　out　and　several　stirrups　were　fractured.　The　cover　concrete　in　the　mid-height　section　of　specimens　were　spalled　seriously.　However,　the　core　concrete　of　specimens　was　not　crushed.　The　axial　compressive　bearing　capacity　and　deformation　ability　of　reinforced　concrete　columns　could　be　improved　by　close　confinement.　When　specimens　reached　the　ultimate　bearing　capacity,　the　longitudinal　reinforcement　was　yielded　and　provided　axial　bearing　capacity　for　specimens.　The　transverse　reinforcement　reached　tensile　yield　strength　and　provided　effective　confinement　for　the　core　concrete.　The　stress-strain　relationship　before　peak　stress　and　the　peak　stress　were　well　predicted　by　existing　stress-strain　model　based　on　small　size　specimens,　but　the　peak　strain　and　the　deformation　ability　after　peak　stress　may　be　overvalued.
