Comparative Analysis of Design Solutions of Metal Silos

Abstract

<jats:p>Concept of bulk material and complexity of storing it are explained. The dependence between the physical and mechanicalproperties of the loose material and type of construction in which it is stored. Structural elements considered silos and siloswith conical and flat bottom are described. The common characteristics of metal silos for bulk materials are given. The classification of metal silos by type of housing design is given. The advantages and disadvantages of silos are described.The possibility of storage of bulk materials in cylindrical shells is analyzed depending on the type of construction. The history of occurrence of structures of spiral-fold silos is considered. The set of equipment for the construction of the housing ofthe spiral-fold silos is given, the step-by-step process of formation of the folding lock and features of the installation processare presented. The analysis of the structure is made and the advantages and disadvantages of spiral-fold silos are determined.</jats:p>

Features of structures and calculation of steel spiral-fold silos

“…The development of these progressive structures is constrained by the lack of studies of the stress-strain state of these shells because these structures have a folding lock. A number of domestic and foreign scientists have been engaged in the analysis of structures, calculation methods and experimental studies of cylindrical shells of metal silos for strength and stability [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Mileykovsky et al [5] in their work presented a computational model of the shell in the form of a scan of a cylindrical surface, which is considered as a ribbed plate with inclined edges.…”
