Modelling of the heating process of a building structure with a protective fire-resistant coating

The paper considers the issues of increasing the fire resistance of reinforced concrete building structures of industrial enterprises. The authors provide data on fires at industrial enterprises and infrastructure facilities and analyse the damage caused. The paper offers the author's method of increasing the fire resistance of structures by applying protective coatings to their surface. The authors have performed numerical experiments for unsteady heat transfer in an indoor fire using the ELCUT 6.6 software tool. Modelling of the floor slab heating process proves the effectiveness of the fire protection coating, with a fourfold increase in the fire resistance of the structure.
