High temperature full-scale tests performed on S500M steel grade beams

Two experimental full-scale fire tests have been performed at the University of Liege in order to assess the mechanical resistance of S500 M steel grade at high temperatures. Two similar 4.4 m-long steel beams have been respectively subjected to fast (standard ISO curve) and slow (fixed 5 K/min heating rate) elevations of temperature under a constant mechanical loading. The tests have been successfully reproduced in subsequent finite element analyses using Eurocode 3 steel material law at elevated temperatures, in which a creep component is implicitly taken into account.
