A　comprehensive　experimental　study　on　structural　behaviour　of　stainless　steel　bolted　T-stub　connections　is　presented　in　this　paper.　A　total　of　27　stainless　steel　bolted　T-stubs　with　various　geometric　configurations　were　fabricated　from　hot-rolled　stainless　steel　plates　and　assembled　with　stainless　steel　bolts.　Two　stainless　steel　grades　-　austenitic　EN　1.4301　and　duplex　EN　1.4462,　and　two　other　types　of　stainless　steel　bolts　-　A4-70　and　A4-80,　were　introduced　in　the　experimental　programme.　Tensile　coupon　tests　were　performed　to　determine　the　material　properties　of　the　stainless　steel　plates　and　bolts.　The　bolted　T-stub　specimens　were　tested　under　monotonic　loading,　and　ultimate　resistances,　plastic　deformation　capacities　and　failure　modes　were　obtained.　Based　on　the　experimental　results,　the　existing　design　methods　for　predicting　tension　resistances　of　the　bolted　T-stub　connections,　including　design　provisions　in　EN　1993-1-8,　the　continuous　strength　method　(CSM),　AISC　manual　and　JGJ　82　and　other　design　formulae　for　T-stubs　with　four　bolts　per　row,　were　all　evaluated.　It　was　indicated　that　all　the　existing　design　methods　provided　generally　conservative　predictions　for　stainless　steel　bolted　T-stub　connections.　(C)　2018　Elsevier　Ltd.　All　rights　reserved.
