Static and Dynamic Silo Loads using Finite Element Models

Different finite element models for axisymmetric silo analysis, that simultaneously considers the behaviour of the grain and the structure, are proposed in this paper. The use of commercial programmes and integration of modern theories on pressures exerted by grain are the main premises of the research. The paper presents models for both the static and dynamic conditions. In both cases, the influence of different parameters is discussed. A new method for emptying pressure determination is also proposed.
