ABSTRACT
The paper presents 3D numerical analysis results on the effect of bulk solid on strength and stability of metal cylindrical silos with corrugated walls without stiffeners during filling. The behaviour of bulk solid was described with a hypoplastic constitutive model. Non-linear FE analyses with both geometric and material non-linearity were performed. The numerical results were compared with the Eurocode formulae. The quantitative estimation of the strengthening effect of the bulk solid stiffness on the silo stability, buckling strength and wall stresses was performed.
