The software package ELCUT was used to simulate the thermophysical processes of the steel structures under consideration, in which the possibility of the numerical simulation of fire resistance of structures has been repeatedly confirmed by the authors of scientific papers.
For example, in [37] the temperature fields during fire exposure of modern windows and facade glazing elements are considered; it is shown that ELCUT makes it possible to predict the behavior of building structures at elevated temperatures and to show the temperature distributions and stress fields.
In [38], a simulation of heating of offshore stationary platform structures in ELCUT is given, which showed good correlation with the experimental data; the consumption of mineral slabs for the bulkhead structure is predicted and the parameters of thermal conductivity and the heat capacity of the applied fire protection in the temperature range from 0 to 1000°C are specified.
In [39], the results of large-scale fire tests of lightweight thin-walled steel structures for fire protection efficiency in the ELCUT are presented. As a result, temperature–time curves of metal structures in the standard fire regime were obtained, which showed a good correlation between the simulation and the experimental data.
