Numerical analysis of a steel frame in a fire situation

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.

The Initial Assessment of the Possibility of Simulation Fire Standard Curve in the Electric Furnace with the Assessment of Chemical Composition Changes in Steel after Cooling Phase

“…Investigations of more significantly prominent structural members with the use of a larger electric furnace. • A finite element modeling of a fire situation and comparison of laboratory and numerical results; some effort, in this case, has already been presented by Szczecina and Nowak [29]. • Assessment of structural members after the fire, as presented by Kossakowski et al [30].…”
