Study of the influence of the window profile material on a single-layer glass panel under standard fire exposure
Keywords:translucent structure, heat transfer coefficient, thermal tension, thermal impact, fire resistance
Purpose. To develop a method for calculating the fire resistance of a single-layer flat glass panel enclosed in a frame under the conditions of standard impact during various fire loads, taking into account the design features of the frame and the thermophysical properties of air, fume gases and the frame.
Methods. Calculations of the temperature and stress distribution of a bounded glass panel are performed numerically using the FlexPDE software package.
Findings. The distribution of temperature and stresses in a single-layer flat glass panel enclosed in a window profile is calculated, taking into account the temperature dependence of the thermophysical characteristics of glass, air and flue gases, the design features of the translucent structure and the nonlinear nature of the change in the ambient temperature during a fire. The effect of the material of the window profile on the destruction of a single-layer flat glass panel enclosed in a frame under conditions of standard fire exposure under various fire loads has been investigated.
Application field of research. The results of the study can be used in the design of buildings and structures to ensure safe operation and evacuation in the event of a fire.
