By　referring　to　the　two　different　loading　protocols　from　JGJ/T　101-2015　and　FEMA　461,　cyclic　loading　tests　on　a　total　of　16　stainless　steel　(austenitic　S30408　and　duplex　S22253)　and　four　carbon　steel　(Q345B)　bolted　T-stub　connections　were　carried　out　to　investigate　the　hysteretic　behavior.　The　hysteretic　curves　and　the　failure　modes　of　the　tested　T-stubs　were　obtained,　together　with　the　cyclic　hardening,　strength　degradation　behavior　and　the　energy　dissipation　capacity.　It　is　revealed　that　the　stainless　steel　T-stubs　exhibit　much　more　favorable　hysteretic　behavior　than　the　carbon　steel　counterparts,　and　the　energy　dissipation　of　the　tested　stainless　steel　T-stubs　is　about　2.07　times　that　of　the　carbon　steel　ones.　Two　typical　failure　modes　including　the　bolt　fracture　and　the　flange　fracture　adjacent　to　the　weld　toe　are　displayed,　which　are　dependent　on　the　corresponding　static　failure　mode　and　the　loading　protocol.　The　T-stubs　in　both　stainless　steel　grades　exhibit　considerable　cyclic　hardening　behavior　under　cyclic　loading,　and　display　strength　degradation　during　later　stages　of　tests　due　to　the　occurrence　and　development　of　cracks.　Moreover,　the　obtained　number　of　load　cycles　and　the　energy　dissipation　capacity　from　the　JGJ/T　101-2015　loading　protocol　are　both　higher　than　those　from　the　FEMA　461　loading　protocol　for　the　tested　T-stubs.　©　2022,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
