STABILITY OF STEEL COLUMNS IN CASE OF FIRE - EXPERIMENTAL EVALUATION

Two new series of experimental full-scale tests have been performed on steel columns at elevated temperature, either under small or large ec centricities. Those results have been introduced in a database, togeth er with results from previous tests found in the literature. An analyt ical formula for the buckling coefficient presented as shown in an ear lier paper has been calibrated here by comparison with the results of tests made with no or with small eccentricity. The analytical proposal for a P-M interaction curve presented in the companion paper has been compared in this paper with all the results from the database, and pr oved to provide a satisfactory agreement.
