Monitoring of structures in conditions of beyond design basis impacts, including fire and similar impacts associated with exposure to elevated temperatures, which is relevant for both civil and industrial buildings, is especially important. The least studied area is the behavior of compressed-bent masonry structures in such conditions. Based on experimental data, a numerical analysis of compressed-bent masonry structures was carried out. Elevated temperatures from 500 to 1200 degrees were taken. Moreover, we took into account the change in the deformation-strength properties of the masonry depending on temperature, as well as the uneven heating of the structures and the stage of their cooling. The analysis results showed that at the stage of heating and maintaining a high temperature, the behavior of structure changes slightly, with the exception of temperatures of 1000-1200 degrees, when the material becomes ultra-brittle. It was also revealed that the most dangerous stage of cooling at the initial temperature rise above 800 degrees. This circumstance can be taken into account when developing monitoring systems for industrial facilities.
