A comparison of the rise of the temperature of an unprotected steel column subjected to the standard fire curve ISO 834 and to a natural fire model in the office

This paper presents a comparison of the changes in the temperature of a steel HEB 300 section column in a standard fire curve and in a natural fire. The EN 1991-1-2 standard and the fire dynamics simulator (FDS) were used to calculate the temperature of the steel column in a fire situation. The temperature of the steel column based on Eurocodes using the ISO 834 curve was different from the temperature obtained from the fire dynamics simulator, modeling a natural fire.

The redistribution of interstitials (C, N) and phase profiles in heterogeneous laboratory weldjoints of the 6CrMoV 8-3-2 and X12CrMoVNb 10-1 nitrided heat-resistant steels were calculated. For the calculations Thermo-Calc and DICTRA software packages were ušed. The results from the simulation were compared with experimental observations. A relatively good agreement between the simulation and the experiments was observed.
