Abstract

The paper deals with buckling of cylindrical metal silos with corrugated sheets and columns. Attention was paid to local buckling of cold-formed open-sectional thin-walled columns in metal cylindrical silos with corrugated sheets. The effect of the column profile dimensions, silo height, silo diameter, corrugated wall thickness, column number/column distance, corrugation height and bulk solid's type was comprehensively investigated. Three-dimensional linear bifurcation analyses were performed for silos using the finite element method and compared with analytical formulae of Eurocode 3. Based on calculation outcomes some recommendations for silo dimensioning were elaborated.
