Local buckling of hot-rolled stainless steel channel section stub columns after exposure to fire

Shear resistance and design of stainless steel plate girders in fire

“…In Gardner and Baddoo [14], stainless steel beams were also tested in fire. In addition to the experiments on stainless steel elements in fire, He et al [28][29][30], Lan et al [31] also tested stainless steel members following their exposure to fire.…”

Behaviour and design of hot-rolled stainless steel channel section members

“…The world's first experimental and numerical investigations into the flexural buckling behaviour and resistance of hot-rolled stainless steel channel section columns have been reported in Chapter 6 (Li et al 2021). An experimental programme includes initial global and local geometric imperfection measurements and pin-ended compression tests on ten hot-rolled stainless steel channel section column specimens.…”

“…The continuous strength method (Afshan and Gardner 2013;Zhao et al 2017;Zhao and Gardner 2018) is an advanced deformation-based design method, which allows for proper consideration of material strain hardening in determining cross-section resistances under isolated loading. The CSM had been shown to result in accurate and consistent compression and bending resistances of stainless steel channel sections (Zhao and Gardner 2018;Zhang et al 2020a;Lan et al 2021;) and the CSM crosssection compression and bending resistances are ideal end points for the new improved design interaction curve. The use of the CSM for the calculation of crosssection resistances under pure compression has been described in Section 3.5 and the CSM cross-section compression resistance Ncsm,Rd is given by Equation (3.12).…”

“…The four-node doubly curved shell element S4R (ABAQUS 2014), which is provided in the ABAQUS element library and allows for finite membrane strains and large rotations, has been widely and successfully adopted in previous nonlinear numerical modelling of thin-walled steel (carbon steel (Xiang et al 2019;Wang et al 2020aWang et al , 2020b, aluminium alloy (Zhu et al 2019;Zhou and Young 2020) and stainless steel (Becque and Rasmussen 2009b;Dobrić et al 2017Dobrić et al , 2020Liang et al 2019aLiang et al , 2019bLiang et al , 2020Lan et al 2021)) channel section members and was also employed herein. A prior mesh sensitivity study considering mesh sizes varying between 0.2t×0.2t and 2t×2t was conducted to seek suitable element sizes which could result in a good balance between computational efficiency and accuracy.…”
