Registration Date 11-02-2022 Organization Cherkasy Fire Safety Institute named after Heroes of Chernobyl, National University of Civil Protection of Ukraine popup.description2 The purpose of this work is to create on methodological and scientific grounds for predicting the crushes and through holes appearance in hedged reinforced concrete structures as the result of fire heat influence. The object of research is the processes of heat in the hedged reinforced concrete structures and the parameters of the stress-strain state of such structures considering the crushes and through holes appearance. The subject of research is precision methods of the class of fire resistance estimation with limit state of entirety loss for the hedged reinforced concrete structures on the base of the general theoretical approach with use finite element method. 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 with limit state of entirety loss was carried out; experimental research of heat transfer under condition of the heat fire influence on hedged reinforced concrete structures was carried out; the general directions of the main procedures of precision calculate method of fire resistance estimation with limit state of entirety loss for the hedged reinforced concrete structures was realized.
