Abstract
Problem statement. Based on the fire safety concept in the state program of Ukraine, the issue of flammability reducing for materials and fire resistance increasing for structures is selected as one of the priority scientific areas in fundamental and applied research. It provides for the implementation of works aimed at ensuring fire protection, the development of fire protection products that reduce the flammability of materials and increase the fire resistance of building structures, the development and improvement of methods for determining the fire hazard of materials. The purpose of the article. Increasing the fire resistance of metal structures due to the use of fire-resistant intumescent coatings, developing new approaches, criteria and methods for assessing fire resistance and increasing the fire resistance of modern metal structures. Conclusions. As a result of the analytical studies, mathematical models were obtained that allow predicting the fire resistance and increasing the fire resistance for metal structures depending on the thickness of the coating, the given thickness of the metal and the type of fire retardant composition. An engineering methodology for assessing fire resistance and increasing the fire resistance of steel structures was developed.
