A　novel　bolted　connection　for　prefabricated　modular　structures　is　proposed.　Five　full-scale　joint　specimens　were　tested　under　cyclic　loads,　and　finite　element　analysis　was　conducted　to　investigate　the　joint　performance.　The　influences　of　the　bolt　diameter,　the　column　flange　thickness,　the　connecting　plate　thickness,　and　the　connection　forms　between　beam　flanges　of　the　upper　and　the　lower　box　modules　were　analyzed,　and　the　joint　rotational　stiffness　was　evaluated.　According　to　the　results,　the　bolted　beam　flanges　can　significantly　improve　the　hysteretic　performance,　yield　resistance,　ultimate　resistance　and　energy　dissipation　capacity　of　the　joint.　A　thin　connecting　plate　can　effectively　prevent　the　yielding　of　the　ceiling　beam　web.　The　joint　can　be　classified　as　a　full-strength　according　to　the　Eurocode.　Simplified　formulas　for　the　yield　and　ultimate　resistances　were　proposed　and　evaluated　to　be　accurate　and　practical　for　performance　predictions　and　design　of　the　proposed　joint.
