The purpose of this article was to determine the dependence of the values of the boundary of the fire resistance of the bearing walls on the temperature dispersion on their heating surfaces as a scientific basis for improving the efficiency of the evaluation of the results of fire tests. In this paper, the problem of strength was determined to determine the bearing capacity of a reinforced concrete wall in a fire. During work, computational experiments using CFD and the finite element method were used. As a result of the studies, the dependence of the design values of the fire resistance of the reinforced concrete wall on the value of the maximum temperature dispersion on the heating surface of the structure during the fire tests and the error of the definition of the fire resistance limit was obtained, as well as the recommendations for creating new and improving existing furnace chambers from the tests on the fire resistance of the vertical reinforced concrete building constructions.
