The scientific work includes the development and implementation of the latest scientific and technical solutions in the field of agricultural construction. The solutions are related to the design and construction of granaries that meet the requirements of reliability and survivability and work in design and special conditions of wartime. The basis of the work was the author's methodology of reliability of granary structures developed for the first time. This takes into account the stochastic properties of steel and the effect of random loads; new data from experimental tests of various classes of steel and new results of a large-scale numerical experiment modeling wind impacts on the silo park system. The paper has improved the economic-probabilistic approach to determining the risks of failure of granaries. On this basis, new analytical dependences have been obtained for optimal levels of reliability of granary structures.

The experimental and theoretical results obtained develop the scientific direction of reliability calculation for the creation of highly reliable and economical building structures. They can also be used for a wide range of practical tasks of designing or checking calculation of granaries. The uniqueness and scale of the work is due to the fact that for the first time dozens of structural solutions of steel granaries of world manufacturers have been analyzed from a unified standpoint of reliability, survivability and economic feasibility. The information material was summarized and analyzed, which allowed us to obtain optimal design solutions for granaries for working in normal and special conditions of wartime. These solutions are being actively implemented by domestic silo manufacturers. They not only provide Ukrainian farmers with reliable and economical granaries in the world, but also serve as a scientific and technical basis for creating a single information hub for the serial design of agricultural sector facilities.
