The object of research is the processes of heat and mass transfer and the parameters of the stress-strain state of building structures during the fire resistance test. The subject of research is methods of estimation of a class of fire resistance of building designs on the basis of tests of their small-sized fragments. During the reporting period, a prototype of the test installation was created; the necessary number of experimental tests on the fire resistance of elements of building structures were carried out; computational experiments were carried out in computer models similar to the real furnace; based on calculated and experimental data, a scientifically based method of assessing the fire resistance limit of building construction elements is systematized; conclusions and proposals were formed based on the results of the scientific research work; a report on the topic was prepared; proposals have been prepared for setting up new GDRs.   Product Description popup.authors Yelahin Heorhii I Aleksieieva Olena S Zemlianskyi Oleg M Kasiarum Serhii O Kryshtal Dmytro O Nedilko Inna A Perehin Alina V Pozdieiev Serhii V.
