Keywords:fire resistance, standard fire temperature, relative thickness, computer simulation, temperature field, anisotropy, thermotechnical calculation, Ansys Workbench
Purpose. To determine the temperature field of a centrifuged reinforced concrete column exposed to standard fire temperature regime around the external perimeter. Methods: Computer simulation based on the results of experimental and theoretical studies of the physical and thermophysical properties of centrifuged concrete. Thermotechnical calculations according to the current technological regulations.
Findings. A computational computer model was developed for modeling the heat transfer of a centrifuged reinforced concrete column with a fire gaseous atmosphere. The temperature field of the centrifuged reinforced concrete construction of the annular section is determined at a given point in time due to the standard fire exposure all around. The simulation results are compared with the data obtained from calculation by engineering methods according to the current technical regulations.
Application field of research. The results of the study can be used to determine fire resistance limits of the centrifuged reinforced concrete constructions. The obtained data are planned to be compared with experimental data.
