Behaviour of thin-walled cold-formed steel structures in fire

Thin-walled cold-formed steel (CFS) members have become increasingly popular over the last decades in the light-steel frame (LSF) construction industry as primary load-bearing members. Valuable properties of CFS arise from the manufacturing process, while the undesirable ones, such as cross-section and member instabilities, are especially pronounced at extreme temperatures. Considering present-day stringent fire safety regulations, which require that all buildings and their structural components perform safely in fire situations, structural designers have to make greater efforts to understand complex structural behaviour at elevated temperatures. Besides laboratory testing, numerical analyses provide adequate and economic solutions for better understanding and predicting such complex behaviour.
