Прогрев стержневых стальных конструкций с частичной и полной огнезащитой наружной поверхности при огневом воздействии
Purpose. Based on experimental studies and theoretical data, to determine the thermophysical characteristics of the intumescent flame retardant and evaluate the heating of rod steel structures with partial (tripartite) and full fire protection of the outer surface under conditions of high temperatures in comparison with the results of fire tests. Methods. Experimental studies, modeling in the system of finite element analysis. Findings. Based on a series of experimental and theoretical studies in the ANSYS finite element analysis system, the heat engineering problem of fire resistance of steel structures with partial and full fire protection of the outer surface is solved. Experimental studies were used to evaluate the effective values of the thermal and physical characteristics of the intumescent composition (Sika Unitherm ASR) by solving the inverse heat conduction problem for the calculated finite element model using parametric optimization methods. The obtained thermal and physical characteristics made it possible to evaluate the heating of steel structures with partial and full fire protection of the outer surface under conditions of high temperatures and compare that with the results of fire tests. Application field of research. The results can be used to solve the fire resistance problems of rod steel structures with partial and full fire protection of the outer surface while designing and constructing buildings and structures.
