"This paper presents research in behaviour of laterally unrestrained steel beams (I or H section) of Class 4 cross-sections at elevated temperatures, which is based on the RFCS project FIDESC4 - Fire Design of Steel Members with Welded or Hot-rolled Class 4 Cross-sections. Three Class 4 section beams were tested at temperatures 450 and 650\u00B0C. One of the beams was tapered. The tests were subsequently used for a FE model validation. Later, a parametric study was performed in general FE software ABAQUS. Finally, all the numerical data are shown and compared to existing design codes."@en .
