Abstract:

In the paper, the stages of modelling of a steel frame under fire conditions were discussed. Numerical
computations were performed using SIMULIA Abaqus software. The way of defining and
developing
the computational model was described. In the numerical procedure adopted in the paper, much attention
was paid to formulas related to various types of the model parameters that depend on the fire
temperature. The results were shown in a graphic
form. They were compared with the results obtained
from the analysis, in which the impact of elevated temperatures was disregarded. Based on numerical
simulation results, an attempt was made to assess the effect of fire on the steel frame components. The
paper is exploratory in character and provides an introduction to the issues related to the modelling of
steel structure fires. The numerical modelling of the structure fire described in the paper can have
practical potential for structural engineers.
