Abstract

The article proposes an algorithm for analyzing the temperature distribution on the surface of building structures, which takes into account spatial and temporal parameters of thermal impact. The main stages of the algorithm include input data collection, pre-processing, temperature distribution modeling, spatial and temporal analysis, interpretation of results and making appropriate decisions.
The possibilities of non-contact temperature measurement methods, such as thermal imaging, which allow for effective identification of fire centers, are described.
The criteria for assessing the degree of damage to building structures based on the obtained temperature characteristics are considered, including the maximum temperature, its distribution across structures, the rate of temperature change, the duration of exposure to high temperatures, the physicochemical properties of materials, as well as visual and instrumental changes. The main parameters for predicting the further development of damage and assessing the risks of secondary damage are determined.
The prospects for implementing thermal imaging monitoring in the field of fire safety of critical infrastructure facilities are outlined.
The proposed methodology for rapid assessment of damage to building structures after emergency events includes preparation for measurements, collection of input data, conducting thermal imaging surveys, analyzing temperature characteristics, assessing the extent of damage and identifying risks, and making decisions on further measures. The use of this methodology will contribute to a quick and accurate determination of the condition of structures and will prevent their further destruction.
