In this work, it is substantiated that it is possible to create a fire installation with parameters that will ensure higher environmental friendliness of the tests compared to large-sized furnaces. At the same time, its configuration will be universal, compact and capable of high reproducibility of experimental results. A full factorial experiment was conducted. According to its results, the parameters of the furnace chamber, which most significantly affect the reproducibility of the results, were determined. This are the volume of the chamber, the distance from the burners to the surface of the examined fragment of the load-bearing reinforced concrete building structure, and the height at which the opening for the exit of combustion products is located. Adequacy of operation of the designed installation was verified by the computer simulation method. Natural gas was used as fuel. On the basis of the received data, a sketch of the installation was created for conducting the experimental part of evaluating the fire resistance of load-bearing reinforced concrete building structures under the influence of the standard fire temperature regime. It can ensure a high degree of reproducibility of the test results.
