The　design　for　traditional　steel　rigid　connections　cannot　fully　meet　the　desired　seismic　requirements,　though　beam-column　connections　with　weakened　beam　end　can　approximately　realize　the　concept　of　＇strong　column-weak　beam＇,　in　which　the　local　buckling　in　the　weakened　zone　and　the　overall　lateral　may　occur　in　strong　earthquakes　and　have　insufficient　capacity.　A　replaceable　steel　connection　with　low　yield　point　metal　was　proposed,　based　on　the　concept　of　earthquake-resilient　structures.　In　this　connection,　the　weakened　parts　in　the　flange　slab　and　web　plate　were　filled　with　low　yield　point　metal,　which　yields　then　dissipates　sufficient　energy　in　earthquakes.　Thus,　damage　to　the　main　parts　in　the　connection　was　slight,　and　the　yield　point　metal　could　be　replaced　after　the　earthquake.　The　low　yield　point　steel　was　selected　as　the　replacement　material,　and　the　material　constitutive　relationship　was　obtained　by　a　performance　test.　The　seismic　performance　of　the　three　types　of　connections,　which　include　the　traditional　connection,　beam　end　weaken　connection,　and　replaceable　connection　under　low　cycle　reciprocating　load,　were　studied　using　the　finite　element　method.　In　addition,　the　energy　dissipation　capacity　and　damage　characteristics　of　different　connections　were　compared.　The　multi-scale　finite　element　models　for　the　steel　frames　with　different　connections　were　analyzed　by　the　inelastic　time-history　method.　Both　the　computational　efficiency　and　accuracy　were　assured.　The　analysis　results　approve　that　the　replaceable　connection　can　confine　major　damage　in　the　replacement　material　and　have　better　energy　dissipation　ability,　safety　reserves　and　resilience.　©　2016,　Editorial　Department　of　JVMD.　All　right　reserved.
