摘要：

In　this　paper,　the　axial　compression　tests　were　carried　out　on　the　concrete　filled　steel　tube　(CFST)　column-reinforced　concrete　(RC)　beam　joints　connected　by　steel　plates　and　studs　after　the　low-cycle　reversed　loading　test.　The　failure　mode,　steel　tube　strain　and　ultimate　bearing　capacity　of　new　types　joints　were　discussed　under　axial　compression　load.　The　comparative　study　with　the　specimen　of　CFST　column　was　conducted.　The　results　showed　that　new　types　CFST　column-RC　beam　joints　maintain　good　axial　compression　performance　after　the　low-cycle　reversed　test　loading　at　the　beam　ends.　The　specimens　were　designed　following　the　principle　of　＇strong　column-weak　beam＇.　The　low-cycle　reversed　loading　had　little　effect　on　the　axial　bearing　capacity　of　the　CFST　column,　but　the　damaged　RC　beams　of　the　joints　had　certain　influence　on　the　failure　mode　of　the　columns　under　axial　compression.　©　2019　IOP　Publishing　Ltd.　All　rights　reserved.
