description: This work is devoted to the study of changes in the values of the strength characteristics of brickwork when working under conditions of constantly changing thermal influences in the pipes of boiler houses. Tasks that were solved in the course of the study: 1. Study of the work of brickwork in the conditions of boiler pipes. 2. Conducting practical experiments to study the drop in strength characteristics of bricks. 3. Calculation of the drop in strength characteristics relative to the operating time, and development of recommendations for the use of the obtained values for scaling them to similar structures. The study is based on a survey of the boiler house chimney made of ceramic bricks. Due to the unusual cyclicity and constant heat exposure, these bricks are subjected to increased exposure to aggressive environments. on the basis of the operating time and the conducted practical experiments, a comparative analysis is carried out and the drop in the strength characteristics of the samples relative to the thermal impact and service life is calculated. As a result, a static calculation of the pipe structure was carried out and the load values of the tested samples were identified, then, based on experimental data on determining the strength of bricks, the values of the drop in strength characteristics for compression and bending were determined for 1 cycle-day of operation and relative to one Watt of thermal energy received by the samples during operation. Based on these data, recommendations were proposed for calculating the residual strength of brickwork in similar structures.
