Purpose - the scientific rationale for the use of methods to assess the parameter estimates of fire resistance of building structures and defining characteristics of the flame retardant abilities of flame retardants. Methodology of research - experimental methods for studying the behavior of the samples during heating, regulated requirements of DSTU B V.1.1-4-98 "Protection against fire. Building structures. Methods of test for fire resistance. General requirements" mathematical and computer modeling of unsteady heat transfer in different systems, the determination of thermophysical properties and characteristics of the flame-retardant coating ability of metal, concrete floors on the basis of the solution of direct and inverse heat conduction problems. On the basis of analysis of the question assessment of fire resistance of metal, reinforced concrete structures revealed that the increasing use of Calculated and experimental method, more economical and reliable, compared with an experiment or calculation. On the basis of the refined model of differential thermal conductivity and a common approach to solving the inverse heat conduction problems improved method for determining the ability of fire retardant coatings of metal structures. With the help of the developed methodological support the use of cash-for experimental method for predicting the parameters of fire resistance of sandwich walls (sandwich panels) for buildings and structures to determine the temperature dependence of the effective thermal conductivity and heat capacity. The technique of determining the ability of fire retardant coatings hollow concrete floors on the basis of loss of heat insulating capacity or achieve reinforcement of the critical temperature for a given level of loading. Tags: fire, fire-retardant capacity, thermal characteristics, fireproof coating, calculation and experimental method.
