Abstract
The target of the investigation is a water tank with an internal volume of 1.5 m3.
This pressure vessel is supported by legs. This study compares four different cross sections
of the support, when exposed to fire. Different steel grades were used for the comparison.
During the fire, the temperature rises continuously, and with it, the yield strength of the
steel decreases. The purpose of the calculation is to determine how long the structure can
withstand buckling.
