To　realize　the　assembly　between　beam　and　column　and　the　assembly　between　column　and　column,　a　type　of　bolt-assembled　beam-to-column　and　column-to-column　connections　for　special-shaped　concrete-filled　steel　tubular　columns　and　H-shaped　steel　beams　in　a　prefabricated　multi-story　and　high-rise　steel　structure　was　proposed.　Four　modules　including　the　upper　column,　lower　column,　L-shaped　connectors　and　H-shaped　steel　beam　were　fabricated　in　the　factory　and　assembled　on　site　by　bolts.　The　fast　connecting　between　beam　and　column,　and　between　column　and　column　were　realized.　Four　joints　were　fabricated　by　varying　the　number　of　cover　bolts　and　the　type　of　stiffeners.　Pseudo-static　tests　and　finite　element　analysis　were　performed　on　the　four　joints.　The　hysteretic　loops,　failure　modes,　skeleton　curves,　energy　dissipation　capacity,　load　carrying　capacity,　ductility　were　obtained,　as　well　as　variation　of　the　tensile　force　in　the　bolts.　The　results　show　that　the　hysteretic　loops　of　the　four　connections　are　shuttle-shaped,　indicating　that　the　connections　have　good　seismic　performance　and　energy　dissipation　capacity.　The　bolt-assembled　connections　have　excellent　deformation　capacity,　and　the　plastic　rotation　angles　of　the　four　connections　are　more　than　0.04　rad.　The　yield　load　and　ultimate　load　of　the　connection　increase　significantly　with　the　number　of　cover　bolts.　The　vertical　stiffener　of　the　beam　can　prevent　local　buckling　of　the　beam　flange　and　facilitate　the　post-earthquake　repair.　The　slipping　between　the　cover　plate　and　the　beam　flange　realizes　slip　energy　dissipation,　and　increases　the　ductility　and　energy　dissipation　of　the　connection.　The　finite　element　software　is　used　for　parametric　analysis,　which　shows　that　the　joints　are　rigidly　connected　when　the　thickness　of　the　cover　plate　and　the　thickness　of　the　pallet　vary　within　8-20　mm.　©　2022,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
