In the paper a simplified stability analysis of steel cylindrical silos composed of corru¬gated walls and vertical open-sectional columns was proposed. The whole 3D silo was modeled as a single column resting on elastic foundation provided by the silo walls. In proposed formula for the calculation of the foundation stiffness the curvature of the silo walls was taken into account. Three different analyses were carried out using commercial FE package ABAQUS: linear buckling, dynamic with the geometric non-linearity and dynamic with the both geometric and material non-linearity. Axisymmetric and non axisymmetric loads imposed by a bulk solid following Eurocode 1 were considered. The calculated buck¬ling loads were compared with the permissible one given by Eurocode 3 and with results found for the whole silo modeled by shell elements.
