Numerical Simulation and Design of Stainless Steel Columns under Elevated Temperatures
This paper presents and discusses the first results of an ongoing Abaqus numerical (shell finite element) investigation on stainless steel columns under elevated temperatures and prone to local or global buckling, performed in the context of the project “StaSteFi ‐ Fire Design of Stainless Steel Members”. In particular, geometrically and materially non‐linear shell finite element models are employed to obtain the failure loads of columns (i) with several cross‐section shapes (SHS, RHS, CHS, EHS and I‐section), (ii) prone to local or global buckling, (iii) made from three stainless steel grades (ferritic 1.4003, austenitic 1.4301 and duplex 1.4462), (iv) subjected to various elevated temperatures (θ=100, 200, 300, 400, 500, 600, 700 and 800°C) and (v) containing both initial geometrical imperfections and residual stresses. The failure loads gathered are then used to assess the prediction quality of the Eurocode 3 stainless steel design rules and explore the development and calibration of novel design approaches.
