Abstract

The design of storage structures requires, above all, the calculation of the normal pressures on silos walls. Two methods of calculation are generally used, the analytical and the numerical method. The analytical method is generally used for practical and rapid calculations of the silos. However, if we consider the complex behaviour of the ensiled material, the effect of the wall flexibility and the behaviour of the material-wall interface, only a numerical finite element technique can be used. Earlier studies, using this method, often consider a complex behaviour of the ensiled material. Our aim is to study the pressure distributions in circular silos with flexible walls and to show that comparatively simple finite element techniques, which include
