description: The final qualifying work is devoted to taking into account the heat release of concrete in the calculations of the thermal crack resistance of massive reinforced concrete structures; this is a very important and urgent task during the construction period for various objects, from residential and administrative high-rise buildings to nuclear industry facilities and the construction of hydraulic structures. During the study, the following tasks were solved: 1) analytical description of the effect of heat reduction on the thermal crack resistance of massive reinforced concrete structures in the first 40 hours based on experimental data; 2) creating an additional block in the TERM program allows you to take into account the effect of heat generation at any time; 3) next, a numerical measurement of the result of the heat release of concrete under various technological conditions for its laying. The work carried out calculations and research to improve the methodology for determining the thermal crack resistance of massive reinforced concrete structures based on experimental and theoretical data. The thermally stressed state of a massive monolithic reinforced concrete foundation slab of a nuclear power plant, continuously concreted to its entire height, with and without corrections in the heat release equation, was studied. A comparative assessment of the results of calculating the thermally stressed state of a massive concrete structure resulting from the cement hydration reaction was carried out using the equation I.D. Zaporozhets in its original and corrected form. A check was carried out to ensure the thermal cracking of the structure, based on the results of which the minimum required thickness of special thermal insulation was determined.
