ABSTRACT
Internal ties are used in square or rectangular silos with thin walls to bound the out-of-deformations of the panels. In France, Germany and other agri cultural countries, this concept of associated ties and panels is widely applied. One of the advantages of this structure is the ease of building and repairing the silo, and the structural effects are easier to calculate. Rectan gular bins tend to have large reserves of strength. This is not generally the case with circular silos for which care is needed in design to prevent overstress or buckling of the silo wall. Material loads in the silo are applied directly to the wall plate, and transferred via the plate to the ties and to the stiffeners. Frictional forces result in vertical compression of the wall and, of the column supports, cause in-plane bending of the wall. The main disad vantage is the geometrical arrangement of the ties which disturbs the flow
during discharge, hence provoking the change of the ties’ behaviour (com pression of the ties).
