dc.description.abstractENG: The article presents the results of a dynamic analysis of the structure of a large-sized steel bunker of the Kryvorizhstal plant (Ukraine). The overall dimensions of the bunker are 18 by 15 m in plan with a total height of about 9 m and a net volume of about 1000 m3. The studies were carried out using the finite element method based on the construction-oriented software product SCAD (Ukraine). Variants of the dynamic analysis of an empty structure, as well as structures with a level of loading with bulk material of 12.5%, 25%, 37.5%, 50%, 62.5%, 75%, 87.5% and 100% were considered. As a result, it was found that the frequency spectrum of the steel bunker is quite dense and quantitatively starts at a frequency of about 10 Hz. An increase in the level of bunker loading for every 25% of capacity leads to a decrease in the frequency spectrum by 20-30 % on average. This regularity makes it possible to develop and implement an automated system for controlling the frequency spectrum of unloading devices at the Kryvorizhstal plant.en
