Abstract
•Review on studies performed on CFS members at elevated temperatures is presented.•Buckling modes, ultimate capacity and critical temperature of members are discussed.•Research gaps and needs, as well as new directions for researchers, are highlighted.
CFS members are more vulnerable to fire due to high section factor (fire-exposed area to the heated volume). Hence, an extensive review of experimental and numerical studies performed on CFS beams and columns at elevated temperatures is presented. Various types of buckling under different loading conditions and influence of different factors affecting the ultimate capacity and critical temperature of members are discussed. A comparison between different test methods and fire curves used around the world is presented. The research gaps as well as recommendations are also proposed. Conclusively, this review will provide basic data for the development of design codes.
