description: This work is devoted to the choice of the most optimal solution technique. The object of research is a reinforced concrete floor slab with a fire retardant coating. The subject of research is the strength characteristics of a reinforced concrete structure and its fire resistance limit. Theoretical and mathematical research methods were applied in the dissertation for the purpose of modeling a finite element object and solving thermal problems. Tasks solved in the course of the study: 1. Modeling a reinforced concrete structure with fire-retardant materials in the ANSYS PC and setting the fire effect. 2. Selection of heat transfer coefficients for solving the heat problem. 3. Identification of strength characteristics and indicators of fire resistance limits of reinforced concrete structures. 4. Application of this method of thermal calculation to other problems. When modeling the structure of a reinforced concrete floor and applications, graphs of temperature versus time and over the thickness of the structure were obtained. The static problem was solved, the graphs of the deflections were obtained. When calculating the structure of the floor in the conditions of "standard", R150 were obtained and the moments of internal forces and the moment from an external load were compared, taking into account the bending moment of an uneven position along the thickness of the structure. As a result, the use of various fire retardant materials is shown.
