Strain in deep grain bin walls due to ambient temperature decrease

A series of tests were conducted to determine if tensiles train in deep storage bin walls increased significantly when ambient temperatures decreased. Theoretical analysis, based on beams on elastic foundation theory, was undertaken for a similar deep bin storage case. Experimental work showed an increase in tensile strain occurred when temperatures decreased. The increase was shown to be a function of distance below the top surface of the grain, as well as temperature decrease. The theoretical model was capable of predicting strain increases. A theoretical value fo r the foundation modulus of sorghum grain, en masse, was suggested
