Prefabricated　steel　structure　systems　have　become　a　new　trend　in　the　development　of　steel　structures.　In　particular,　earthquake-resilient　steel　structures　have　become　a　hot　issue　in　the　field　of　structural　seismic　research.　Based　on　the　idea　of　damage　control　and　a　new　kind　of　energy-saving,　material-saving　and　environmentally　friendly　sinusoidal　corrugated　web,　this　paper　put　forward　a　new　type　of　earthquake　resilient　prefabricated　sinusoidal　corrugated　web　beam-column　joint　(PSCWJ).　Then,　its　constitution,　its　mechanics　mechanism　and　its　seismic　design　requirements　are　introduced.　After　considering　the　influence　of　the　bolt　binding　coefficient,　the　overall　bending　of　the　binding　section　and　the　overall　instability　of　the　flange　cover　plate,　the　design　theory　of　the　earthquake-resilient　PSCWJ　is　established.　Through　55　examples　of　PSCWJs,　the　rationality　of　the　design　theory　proposed　in　this　study　is　verified,　and　a　reasonable　value　range　of　the　middle　bolt　interval　on　the　flange　cover　plate　is　determined.　During　the　process　of　theoretical　derivation,　the　influences　of　many　design　parameters　are　considered,　such　as　the　section　parameters　of　the　sinusoidal　corrugated　web　beam　and　cantilever　beam,　the　thickness　of　the　flange　cover　plate,　the　material　properties　of　the　flange　cover　plate,　the　diameter　of　bolts,　the　middle　bolt　interval　and　the　weaken　rate　of　the　cover　plate.　Research　shows　that　the　design　theory　proposed　in　this　paper　can　predict　the　yield　load　of　PSCWJ　accurately　and　effectively　control　the　ultimate　bearing　capacity　of　PSCWJ.　The　PSCWJ　designed　through　this　theory　has　good　bearing　behaviour　and　ductility,　which　can　make　sure　the　main　members,　such　as　the　beam　and　the　column,　remain　in　an　elastic　range　and　meet　the　requirements　of　earthquake　resilience.　(C)　2017　Elsevier　Ltd.　All　rights　reserved.
