Abstract
The article considers and discusses the results of experimental studies to study the features of the thermal regime of a fire at objects with different fire loads. For the experiments, a numerical calculation of temperature fields and an assessment of the fire resistance of load-bearing structures with the functionality of the developed software package are proposed. This software package allows you to automate and optimize the calculation of the temperature regime of a fire in a room and the parameters of the temperature field along the thickness of load-bearing and enclosing structures in case of fire in rooms with different fire loads to assess the fire resistance of building structures. The result of the work was the creation of a special modular software product operating in the Microsoft Office Excel environment with the use of Vissual Basic for Applications and providing online editing of the initial data.

Keywords: temperature field, fire load, temperature regime, software package.
