In　order　to　deal　with　mechanical　properties　and　semi-rigid　characteristics　of　joint　of　steel-concrete　composite　beam　of　CFST　(concrete-filled　steel　tubular)　column　with　stiffening　ring,　the　4　specimens　with　a　scale　of　1:3　are　tested　by　monotonic　loading　and　cyclic　loading.　The　finite　element　models　of　the　CFST　joints　are　analyzed　by　the　finite　element　package　ABAQUS.　The　proposed　finite　element　model　is　validated　by　comparing　the　computed　values,　such　as　strains　and　deformations　of　measuring　points,　with　available　experimental　results.　Based　on　the　models,　a　relative　moment-rotation　curve　of　the　joint　is　proposed.　An　acceptable　correlation　is　observed　through　the　computed　and　experimental　results　obtained　from　the　composite　joint.
