Towards a consistent safety format of steel beam-columns: application of the new interaction formulae from ambient temperature to elevated temperatures. Steel and Composite Structures: International Journal. ISSN 1229-9367. 3:6 p.383-4011229-9367http://hdl.handle.net/10198/2111Two new formulae for the design of beam-columns at room temperature have been proposed into Eurocode 3, prEN 1993-1-1 (2002), and are the result of great efforts made by two working groups that followed different approaches, a French-Belgian team and an Austrian-German one. Under fire conditions the prEN 1993-1-2 (structural fire design) presents formulae, for the design of beam-columns based on the prENV 1993-1-1 (1992). In order to study the possibility of having, in part 1-1 and part 1-2 of the Eurocode 3, the same approach, a numerical research was made using the finite element program SAFIR, developed at the University of Liege for the study of structures subjected to fire.engBeam-columnBucklingLateral-torsional-bucklingFireEurocode 3Numerical modellingjournal article2010-01-3010.12989/scs.2003.3.6.383
