ABSTRACT
The objective of the paper was to study pressure asymmetry in a grain silo resulting from eccentric filling and discharging. The corrugated wall model silo of 2,44 m in diameter and 7,3 m high was used for the study. It was found that the anisotropy of the mass of grain resulting from off-center filling can be used for reduction of the load asymmetry resulting from off-center discharge.

W pracy omówiono wyniki badań asymetrii obciążenia silosu zbożowego podczas niesymetrycznego napełniania i opróżniania. Badania przeprowadzono na modelowym silosie zbożowym o średnicy 2,44 m i wysokości 7,3 m wykonanym z blachy falistej. Wykazano, że do ograniczenia asymetrii obciążenia wywołanej niesymetrycznym opróżnianiem można wykorzystać anizotropię właściwości mechanicznych powstającą podczas niesymetrycznego napełniania.
