Abstract
Purpose. To study thermal processes of the destruction of glazing in the elements of enclosing building structures with translucent elements under the conditions of thermal influence of the standard temperature regime of fire as a scientific basis for expanding the reference base on the thermal properties of glazing materials and bases for the validation of the calculated assessment of the fire resistance of these structures.
Method. The essence of the experimental research method is to create a standard fire temperature regime on model samples of glass elements of enclosing building structures using an experimental installation based on a fire furnace, the fuel system of which ensures the creation of a standard fire temperature regime. With the help of measuring and recording equipment the temperature indicators in the space of the furnace and in the samples are recorded, as well as the onset of the limit states of loss of integrity and heat-insulating capacity.
Results. The article presents the main results of experimental studies of the properties of glazing materials of enclosing building structures with translucent elements under fire conditions. The article examined the temperature indicators of failure or loss of integrity of various types of glazing, including ordinary window glass, tempered glass and glass with an inner layer of flame retardant gel. The results of the work will become a prerequisite for further research in terms of substantiating the design parameters of glass elements of enclosing building structures on their predicted fire resistance limits and fire resistance limit states under the conditions of thermal influence of the standard fire temperature regime.
Scientific novelty. New scientific data were obtained on the behaviour of glazing of enclosing building structures with translucent elements under the conditions of the thermal effect of fire, which is the basis for improving methods for evaluating the fire resistance of structures of this type.
Practical significance. The practical significance of the research consists in obtaining results that can be used to clarify the characteristics of glazing materials of enclosing building structures with translucent elements in fire conditions, as well as creating a basis for verification and validation of the results of calculation methods for assessing the fire resistance of these structures in order to improve them.
Key words: enclosing building structures, glazing, fire resistance limit, fire tests.
