The　experimental　results　on　sixteen　concrete-filled　steel　tube　column-steel　beam　joints　with　external　ring　subjected　to　cyclic　lateral　load　are　generally　introduced　in　this　paper.　It　shows　that　dimension　of　the　ring　influences　the　location　of　plastic　hinge　and　the　failure　model.　It　was　found　that　the　2/3　dimension　of　ring　of　CFSTJR　in　existing　design　code　for　concrete-filled　steel　tubular　structure　is　adoptable,　on　the　base　of　analysis　the　influence　of　the　dimension　of　ring　on　the　bearing　capacity,　strength　and　Rigidity　degradation,　dissipated　energy.　At　last,　some　reasonable　advices　for　design　are　proposed.
