Compared　with　the　traditional　steel　rigid　connection,　the　beam-column　connections　with　weakened　beam　end　have　better　ductility,　but　the　local　buckling　in　the　weakened　zone　and　the　overall　lateral　deformation　may　occur　in　strong　earthquake.　The　replaceable　steel　connection　with　low　yield　point　metal　is　proposed　based　on　the　concept　of　earthquake　resilient　structure.　In　this　connection,　the　weakened　parts　in　the　flange　slab　and　web　plate　are　filled　with　low　yield　point　metal,　and　the　metal　firstly　yields　and　dissipates　energy　sufficiently　in　earthquake;　hence,　the　main　parts　are　intact　and　the　yield　point　metal　can　be　replaced.　The　seismic　performances　of　the　three　types　of　connections　which　include　traditional　connection,　beamend　weakened　connection,　and　replaceable　connection　with　low　yield　point　steel　under　low　cycle　reciprocating　load　are　studied.　In　addition,　the　energy　dissipation　capacity　and　damage　characteristics　of　different　connections　are　compared.　The　multiscale　finite　element　models　for　the　steel　frames　with　different　connections　are　analyzed　by　time-history　method;　both　the　computational　efficiency　and　the　accuracy　are　assured.　The　analysis　results　approve　that　the　replaceable　connection　can　confine　the　major　damage　in　the　replacement　material　and　have　better　energy　dissipation　ability,　safety　reserves,　and　resilient　ability.
