V članku podajamo izraze za membranske sile v osno-simetričnem jeklenem silosu med procesoma polnjenja in praznjenja s sipkim materialom. Izrazi so predstavljeni tudi v grafični obliki, kar omogoča hitro in enostavno oceno velikosti in razporeditve membranskih sil v posameznih delih silosa. Grafi veljajo za poljubno geometrijo silosa in za poljuben material, ki se hrani. Na podlagi teh grafov lahko preverimo, kakšen je vpliv geometrije silosa in shranjenega materiala na razporeditev in velikost membranskih sil. Na koncu podajamo ilustrativen primer izračuna vplivov (pritiskov) in membranskih sil pri polnjenju in praznjenju silosa.

Abstract

In the paper, the expressions for membrane forces in an axisymmetric steel silo structure at filling and discharge with a particulate solid material are presented. Graphical plots of these expressions are given. They can be used for a quick and easy estimate of membrane forces distribution in all parts of a silo structure. The plots are valid for any silo geometry and for any material stored. The influence of silo geometry and stored material properties on the size and distribution of membrane forces can be thus checked. The paper completes with an illustrative example where actions (pressure loads) at filling and discharge on the walls of a silo are computed and the corresponding membrane forces are evaluated.
