Four　scaled　specimens　of　RC　frame　beam　column　interior　joints　(two　cast-in-place　beam-column　joints　and　two　assembled　monolithic　beam-column　joints)　were　designed.　The　specimens　were　tested　under　low-cycle　repeated　loading　under　different　axial　compression　ratios(0.3　and　0.4).　The　important　evaluation　indexes　of　failure　modes,　hysteretic　characteristics,　stiffness　degradation,　energy　dissipation　capacity　and　splicing　strain　variation　of　grouted　sleeves　were　studied.　The　results　show　that　the　energy　dissipation　capacity　of　assembled　monolithic　joints　is　slightly　lower　than　those　of　cast-in-place　joints,　and　the　crack　distribution　and　failure　modes　are　different　obviously.　The　cracks　distribution　of　assembled　monolithic　joints　is　centralized.　The　mainly　regions　of　cracks　are　beam-column　interfaces,　grouted　sleeve　regions　and　middle　cross　sections　of　beam,　but　the　cracks　distribution　of　cast-in-place　joints　are　uniform.　The　effect　of　axial　compression　ratio　on　hysteretic　characteristics　is　not　obvious　in　prime　period　of　loading,　but　the　effects　of　axial　compression　ratio　on　slippage　of　reinforcing　bar　and　shear　deformation　are　obvious　in　the　later　loading　stage.　Based　on　the　experimental　results,　a　simplified　method　of　material　equivalent　treatment　is　proposed　and　different　regions　of　specimen　can　adopt　different　section　properties.　There　is　a　good　agreement　between　the　analytical　results　by　OpenSees　and　the　experimental　results.　©　2017,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
