The paper presents selected results and discussion of model investigations of horizontal silo pressure distribution during eccentric discharging for an outlet located in the lower part of a silo wall conducted at the Białystok University of Technology using a ferrocement circular silo model. Tests were conducted using white mustard seeds were used as the agricultural bulk solid. Pressure were measured using a system of embedded pressure cells. The model studies revealed dynamic characteristics of eccentric pressure changes. Results were compared with the theoretical bulk solid pressures calculated on the basis of Eurocode 1 provisions. The results of these studies confirmed that a non-uniform distribution of discharge pressures occured in the silo wall in the very early stages of the eccentric discharging process. Continuation of eccentric discharge leads to a more uniform pressure distribution.
