Abstract
Silos are the tall containers used to store bulk solids. The article presents results of structural analysis of silo with diameter of 22 m, constructed from high-strength steel S550GD. The research results are of both sci-entific and practical interest. In this study, the mathematical model of the silo was used in the SCAD 21.1 software complex. The silos section was modeled with flat shell finite elements. Vertical stiffeners and roof was modeled with finite bar. An analysis of results of calculations showed that silos element will have strengths reserve. The sheets thicknesses and vertical stiffeners can be reduced. Shown the inappropriateness of applying high strength steel in this field construction. This is evidenced in the case below. The value of safety factor value is follow to one. The structure reliability from such high-strength steels is low. The structure failure takes place quickly, and plastic deformations do not develop. The stress-strain state of structures depends on stress concentration hole.
