The conclusions show that the temperature evolution is slower for outer side fires but, in these cases, the critical temperature of 350 °C is reached earlier in the steel profiles. Finally, this work shows that more studies are necessary to describe the fire resistance of external walls, in particular, when these elements have a loadbearing requirement.englight steel framingexternal wallsnumerical simulationfire resistanceconference paper
