The article presents one of the important problems of developing new types of building structures, in particular fire-resistant doors, related to the need for large-scale studies to assess the impact on the fire resistance of door panels of hardware elements, the variety of which leads to significant costs when conducting a full-fledged analysis. This is also due to the fact that a large number of varieties of such elements are currently being developed and they, in turn, can have different effects on the materials used in the production of door panels, the fire-hazardous characteristics of which are known. As part of the development of a cost-effective approach to the study, a methodology has been developed that allows the analysis of small-sized samples. When testing the method, an analysis of the effect of the thickness of the fabric material and the area of the hardware element on fire resistance was carried out. It is thus fixed that the fittings are a refrigerant - they take on the heat passing through the door leaf material and divert it to the environment. Nevertheless, it has also been recorded that with small thicknesses of the structure and rapid heating of the material layer, it is possible to overheat it and reduce the efficiency of heat dissipation, which leads to a rapid decrease in fire resistance. In the case of placing fittings inside the fire door material, the heat removed is transferred to the outer unheated part of the door, thereby initiating its rapid warming up.fittings are a refrigerant - they take on heat and dissipate it into the environment, nevertheless, with small thicknesses of the structure and rapid heating of the material layer, it may overheat and reduce the efficiency of heat dissipation, and if the fittings are placed inside the fire door material, the heat is transferred to the outer unheated part of the door, thereby initiating its rapid heating. The developed method is a cost-effective option for studying the effect of fittings on the fire resistance of doors when choosing its component parts.
