The load distribution caused by the bulk pressure on the wall of a cylindrical silo chamber (class AAC3) subject to an eccentric discharge, based on the PN-EN 1991-4, was presented in the paper. For silos emptied eccentrically, when eccentricity is greater than one quarter of the silo internal diameter, an additional load on the silo walls should be taken into account. This unsymmetrical load should be considered independently of the local pressure during filling and emptying. An analysis of the flow channel geometry in the silo chamber during eccentric discharge was carried out. Results of the analysis were used as the basis for calculations of the angle specifying the flow zone for chosen bulk solids.
Keywords: silos, eccentric discharge, flow channel.
