DETERMINING THE BEHAVIOR OF A GLASS PANEL UNDER HEATING CONDITIONS DURING A FIRE

Abstract

he object of this study is the processes of heating and destruc- tion of glazing in translucent elements of fencing structures. The paper provides data on the computer simulation of a glass panel be- havior when it is heated on one side under the conditions of exposure to the standard fire temperature regime. With the help of computer simulation of a glass panel under conditions of thermal influence, the process of heat transfer was reproduced based on the non-stationary heat conduction equation. The stress-strain state of the glass panel was considered using the finite element method. The thermal effect was combined with the mechanical load due to the excess pressure that can occur in the room where the fire originates and develops. To study the propagation of cracks in glass, the strength criterion according to the Johnson-Holmquist model was applied.
