The object of the study is the processes of heat and mass transfer and the parameters of the stress-strain state of the building construction of cable tunnels during a fire. The subject of the study is methods of estimation of fire resistance class of cable tunnel building construction taking into account the real temperature of fire and structural features of the tunnel.  The main scientific results are to reveal the patterns of influence of structural characteristics and fire load of cable tunnels on the parameters of fire temperatures and fire resistance of enclosing structures as a scientific basis for creating methods for predicting their fire resistance. The implementation of the results of the work was carried out by publishing monographs " Simulation of fires in cable tunnels" R&D “Substantiation of basic procedures for fire resistance assessment of cable lines of fire-fighting systems taking into account European requirements” (code “Cable lines - fire resistance”) Product Description popup.authors Yelahin Heorhii I Aleksieieva Olena S Gvozd Victor M Dibrova Oleksii S Kyrychenko Oksana V Kryshtal Dmytro O Kryshtal Mykola A Linchevskiy Evgeniy A Nizhnyk Vadym V Nekora Olha V Nuianzin Oleksandr M Pozdieiev Sergеy V Samchenko Taras V Tyshchenko Ievgen О popup.nrat_date 2021-03-17 Close
