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 technical task for research work was specified; the analysis of modern approaches to determination of fire resistance of building designs and development of the sketch of test installation on its basis is carried out; computer simulation of heat and mass transfer during the fire resistance test in the designed installation is carried out; the design features of the test rig were adjusted based on the simulation results and the final version of the prototype of the test rig prototype was created.   Product Description popup.authors Yelahin Heorhii I Aleksieieva Olena S Zemlianskyi Oleg M Kasiarum Serhii O Kryshtal Dmytro O Nedilko Inna A Nuianzin Oleksandr Mykhailovych Perehin Alina V Pozdieiev Serhii V Sidnei Stanislav Оleksandrovych Fedchenko Svitlana M popup.nrat_date 2022-03-09 Close
