AB [EN] Silos are used worldwide to store granular and powdered materials. Agricultural, foodand feed products are commonly stored in silos. However, many questions remain unansweredabout how to estimate the pressures applied by the bulk material, which are needed to design andcalculate the structure of the silo. The complexity of the laws that govern the mechanical behaviorof the stored material along with the low number of experimental stations in the world hinderprogress in this field. The aim of this study was to elucidate the relationship of the hopper angle,flow pattern and vertical stress at the cylinder-to-hopper transition in slender silos. Therefore, a set ofexperiments was conducted on a test station to measure the vertical stress produced by maize at thecylinder-to-hopper transition. Five different hopper angles were used. The experiments comprisedthe filling, the static phase and the discharge. The results obtained show that the hopper angleinfluences the vertical stress at the cylinder-to-hopper transition. Some bottom configurations (flatbottom and bottom with an angle of 30◦) led to vertical stresses that exceeded the value calculatedaccording to Eurocode 1. It is clear that further experimental studies are still necessary to understandthe underlying physical phenomena and the relations between pressures, silo geometry and flowpattern of the stored material.
