“…This work is a continuation of the cycle of works, in particular [4,5], where a small-sized installation is used for conducting experiments to study the thermal effect of a fire on building structures, as well as works [8,9], which note the influence of the uniformity of heating of the investigated structure during its fire resistance tests. This work shows and analyzes the results of experiments on heating a small-sized element of a reinforced concrete beam according to the standard fire temperature regime.…”

The paper analyzes the thermal effect of fire on fragments of reinforced concrete columns based on their heating according to the standard fire temperature regime in a small-sized installation for the study of the thermal effect of fire on building structures. Based on the proposed method, a technique was created that makes it possible to estimate the fire resistance limit of a full-size structure by calculation. The course and results of the conducted fire test are described, and the adequacy and reproducibility of the experimental data are verified. The temperature distribution over the entire area of the fire furnace, the studied fragments was analyzed and the obtained results were processed. The possibility of creating a standard fire temperature regime in the fire furnace chamber has been verified. According to the results of this work, it was established that the heating of the structure at all levels was uniform in the planes of placement of thermocouples, the maximum temperature on the surface was 709 °C, it was observed at the last minute of the experiment and continued to increase linearly, the maximum temperature reached in the center of the rock column was 105 °C, it was observed at the last minute of the experiment and continued to grow linearly; The adequacy of the experimental data was confirmed: the relative deviation did not exceed 4%, and the calculated adequacy criteria (Fisher, Student and Cochrane) were below the critical value.
