摘要：

In　order　to　study　the　mechanical　properties　of　large　diameter　CFST　column-beam　connection　after　earthquake,　axial　compression　test　was　carried　out　on　the　connection　specimens　that　experienced　low　cycle　reversed　loading.　The　failure　shapes,　ultimate　bearing　capacities　and　strains　characteristics　of　the　connection　were　investigated.　The　results　show　that　the　improved　interior　diaphragm　CFST　column-H-shaped　steel　beam　joints　show　waist　drum　failure　modes.　The　column-beam　joints　still　have　high　axial　bearing　capacity　after　cycle　reversed　loading.　The　interior　diaphragms　and　linking　reinforcing　bars　effectively　restrain　the　transverse　deformation　of　the　steel　tube　of　the　connection　zone.　©　2018　Institute　of　Physics　Publishing.　All　rights　reserved.
