Performance of cold-formed stainless steel tubular columns at elevated temperatures

Investigating the role of gradual yielding in stainless steel columns and beams by virtual testing

“…The four-node doubly curved general-purpose shell element with reduced integration S4R, for the structural model, and D4S, for the thermal model, which has performed well in numerous similar applications (e.g. Ng & Gardner, 2007;To & Young, 2008) were used. A suitable mesh size, providing accurate results with practical computational times, with a minimum of ten elements across each plate was adopted.…”

Thin‐Walled Metal Construction

“…Analytical methods for material modeling, including treatment of the highly worked corner regions (Ashraf et al, 2005;Rasmussen, 2003) and complete summaries of imperfections and residual stresses (Cruise and Gardner, 2006), are significantly improving. Web crippling in stainless steel sections has seen recent study Young, 2006, 2007a,b) as has the performance of stainless steel sections at elevated temperatures, that is, fire conditions (Chen and Young, 2006;Gardner and Ng, 2006;Ng and Gardner, 2007;To and Young, 2008).

Testing of stainless steel I-section columns in fire

“…This, coupled with sound mechanical properties, high ductility and excellent durability, has led to stainless steel to be increasingly utilised in structural and offshore applications [3][4][5]. A number of studies into the structural stability of stainless steel members in fire has been performed [6][7][8][9][10][11], but experimental data on stainless steel structural members under fire conditions are rather limited [12][13][14][15]. This is particularly the case for stainless steel I-section members, which are being increasingly utilised to fulfil higher load-carrying capacity requirements in stainless steel structures [16].…”
