A　stiffened　bolted　flange　splice　joint　configuration　with　connecting　plates　and　rebar　hooks　for　concrete-filled　steel　tubular　columns　is　proposed　for　high-rise　prefabricated　steel　structures.　Four　full-scale　specimens　with　different　flange　thickness　or　different　stiffener　layouts　were　tested　under　cyclic　loads,　and　the　hysteretic　behaviors,　performance　indicators,　ductility　and　stiffness　were　analyzed.　Compared　with　conventional　joints,　the　bolted　flange　splice　joints　with　connecting　plates　and　rebar　hooks　show　higher　yield　moments　and　stiffness.　Finite　element　models　that　were　verified　by　test　results　were　established　and　adopted　to　further　analyze　the　seismic　performance　of　these　proposed　joints.　The　rotation　capacity　and　stress　distribution　were　analyzed,　and　the　stiffened　joints　with　connecting　plates　and　rebar　hooks　could　be　regarded　as　rigid　for　high-rise　structures　based　on　the　stiffness.　Parametric　analysis　was　conducted　to　analyze　the　influences　of　connecting　plate　or　rebar　hook　parameters,　proposing　design　recommendations　accordingly.　Formulas　of　the　yield　moments　for　these　stiffened　joints　were　proposed,　and　the　calculated　results　have　good　agreements　with　that　of　tests　and　the　FE　analysis,　indicating　that　the　formulas　could　be　used　in　the　practical　design.
