The　behavior　of　concrete-filled　steel　tubes　(CFST)　subject　to　local　axial　compression　is　analyzed　by　using　the　ABAQUS　software.　Load-deformation　relationship　curves　of　CFST　under　local　compression　are　calculated　and　analyzed.　The　calculated　curves　agree　well　with　the　experiment　curves.　The　influence　of　local　compression　area　ratio,　steel　ratio,　strength　of　steel　and　concrete,　rigidity　of　end　plates　and　so　forth　on　CFST　local　compression　behavior　are　analyzed.　The　results　indicate　that　the　core　concrete　bearing　strength　and　plasticity　would　increase　in　the　local　compression　influence　zone,　which　is　0.8　times　the　diameter　or　1.0　times　the　side　length　of　the　section　of　the　local　compression　end.　This　influence　region　decreases　with　the　increase　of　local　compression　area　ratio.　The　bearing　strength　and　the　plasticity　increase　with　the　increase　of　steel　ratio　and　steel　strength.　The　bearing　strength　increases　with　the　enhanced　concrete　strength,　and　the　plasticity　decreases　with　the　enhanced　concrete　strength.　The　behavior　of　CFST　member　under　local　compression　tends　to　approach　that　of　the　fully　compressed　ones　with　the　increasing　of　end　plate　rigidity.　Finally,　based　on　a　systematic　parameter　analysis,　a　method　of　calculating　the　CFST　local　compression　bearing　capacity　is　proposed.
