A SIMPLE-MODEL FOR THE FIRE RESISTANCE OF AXIALLY-LOADED MEMBERS ACCORDING TO EUROCODE-3

A general model, i.e. a non-linear computer. code, has been extensivel y used to determine the buckling load of axially-loaded members accord ing to the hypotheses of Eurocode 3, Part 10 or Part 1.2, Two yield st rengths, two buckling axes, six ultimate temperatures and 10 different lengths have been considered for 339 different steel H-sections. The numerical results have been statistically sorted and compared to the s imple models presented in Eurocode 3, Part 10 and Eurocode 3, Part 1.2 . The simple models that have been proposed up to now can lead to diff erent safety levels when compared to the general model, the safety lev el depending mainly on the buckling length. A new proposal has thus be en made for a simple model that systematically ensures a conservative result when compared to the general model.
