Experimental study of ferritic stainless steel bolted T-stubs under monotonic loading

“…Similar observations were made in studies investigating the behaviour of stainless steel moment resisting connections [20,21], as well as stainless steel blind-bolted connections [22]. It was found that the design provisions of EN 1993-1-8 [1], which specify design rules for carbon joints, that are also applicable for stainless steel joints [23], are adequate for stiffness predictions but overly conservative for strength predictions [20][21][22]. Wang et al [24], Bu et al [25], Song et al [26] and Gao et al [27] conducted experimental and numerical studies on the behaviour of stainless steel connections and reached similar conclusions.…”

Cyclic behaviour and hysteretic model of austenitic stainless steel bolted T-stubs

“…Moreover, they developed validated numerical models and accurate design expressions for stainless steel T-stubs made of austenitic and duplex stainless steels. Meanwhile, Elflah et al [22][23][24] reported the first experimental and numerical studies on stainless steel beam-to-column bolted connections subjected to static monotonic loads. Hasan et al [25], Wang et al [26] and Gao et al [27] also performed static loading tests on stainless steel beam-to-column joints.…”

Behaviour of Ferritic Stainless Steel Bolted T‐stubs Under Tension‐Part 2: Numerical Investigations

“…Elflah et al [21,22], have examined the behaviour of stainless steel moment resisting connections as well as stainless steel blind-bolted connections [23] with experimental and numerical studies. It was reported that the design provisions of EN 1993-1-8 [1], which specify design rules for carbon joints, that are also applicable for stainless steel joints [24], can predict the stiffness of the joints sufficiently accurate predictions but provides significantly conservative predictions for the strength [21][22][23]. Moreover, the structural behaviour of the moment resisting connections was investigated by three-dimensional FE model and the stiffness and resistance predictions were reported comprehensively, and proposed model validated using the experimental results [22].…”
