Abstract
Wall and bottom loads and the resultant moment of force have been compared for two similar model bins. Corrugated wall bins of 0.6 and 1.2 m in diameter with height-to-diameter ratios of 4 were used in the experiments. The wall and flat bottom of the bins were each supported independently on three load cells to isolate wall and bottom loads. Center and off-center discharge of the bins was tested. The vertical wall load to total grain load and the dimensionless moment found during eccentric discharge were strongly influenced by the difference in the wall friction coefficient resulting from different size corrugations and different kinds of grain. The maximum moment was found for an orifice eccentricity ratio of 0.67 for both bins.
