000004833 520__ $$2eng$$aNumerical prediction of wall pressures in silos has been a major topic of research in the last few decades in the international silos research community. Numerous finite element studies have been carried out on filling pressures in silos. Most of these studies were carried out by treating the self-weight of the ensiled solid as a ‘switch-on’ gravity. However, this approach does not simulate the feature that most silos are filled progressively in practice. Following an early investigation into the effects of ring stiffeners, axisymmetric imperfections and material constitutive models on the wall pressures exerted by the stored iron ore pellets in a full-scale experimental silo, this paper presents some initial numerical predictions of progressive filling pressures. The results are compared with those predicted using a switch-on gravity loading process and the differences are highlighted.
