In　order　to　enhance　the　energy-dissipation　capacity　of　traditional　bolted　T-stub　connections,　two　rectangular　plates　are　proposed　to　be　inserted　between　T-stubs　so　as　to　make　the　T-stub　flanges　yield　in　both　tension　and　compression　loads.　Five　specimens　with　or　without　inserted　plates　were　designed　and　set　up,　then　they　were　experimentally　tested　under　cyclic　loading　conditions.　Test　results　show　that:　the　proposal　to　enhance　the　energy-dissipation　is　feasible;　the　hysteretic　performance　of　the　specimens　with　inserted　plates　is　stable　and　their　load-deformation　loops　are　plump;　the　specimens　with　inserted　plates　can　dissipate　energy　in　both　tension　and　compression　loads,　thusly　the　energy　dissipated　by　them　is　about　150%　of　that　by　the　specimen　without　inserted　plates;　the　bearing　capacity　and　stiffness　under　compression　load　are　larger　than　that　under　tension　one　because　of　different　mechanism;　along　with　the　increase　of　the　plate　width,　the　bearing　capacity　is　improved　in　both　tension　and　compression.
