Abstract
Comprehensive static and dynamic 3D stability finite element analyses of a cylindrical steel silo composed of corrugated sheets and open thin-walled vertical stiffener profiles were carried out by taking the geometric and material non-linearity into account. The silo was subjected to axisymmetric and non-axisymmetric loads imposed by a bulk solid following Eurocode 1. Theoretical and measured initial geometric imperfections were considered in calculations. The results of non-linear analyses were compared to those according to Eurocode 3. Modifications of the Eurocode formulae were proposed. Some recommendations for the silo engineering design were elaborated.
