In percentage terms, about 30% of the total number of fires arise and spread in buildings and structures of industrial, public and residential purposes. It is obvious that the most important importance and influence on the development and spread of fires in buildings and structures is the fire resistance of building structures, which must be taken into account at the design stage. Building codes both in Ukraine and in the world stipulate that all building structures used in the construction of buildings and structures must have certain limits (classes) of fire resistance. Particular attention when used in construction should be paid to steel structures, since their fire resistance limit is about 15 minutes depending on the profile and cross-section of the structure, and this, in turn, limits their use in buildings and structures where the fire resistance class of structures is ˃ REI 15. Methods for increasing the fire resistance class of steel building structures are their fire protection, which can be implemented using special means that protect the steel structure from the effects of high fire temperatures. These means include reactive (intumescent) fire-retardant coatings and the so-called passive fire protection, which is implemented by facing or plastering building structures with non-combustible fire-resistant materials. When using fire-retardant substances and materials, their fire-retardant ability (efficiency) plays a key role. Therefore, research aimed at substantiating the effectiveness of fire-retardant substances (materials) and studying the patterns of the time of reaching the critical temperature in a fire-resistant element of a steel structure depending on the thickness of the fire-retardant coating, the heating temperature of the steel element of the structure, and the cross-sectional coefficient of the fire-resistant steel structure is a relevant task.
