Description: Thermally induced lateral pressures on the bin wall were measured around the circumference (0.9 m above the bin floor) ofa corrugated-steel bin (5.8min diameter, 6.2mhigh).Thebinwas filled with wheat at 10.0 %moisture content (wet basis) to a depth of 5.0 m. Observed lateral pressures varied diurnally, with lower pres sure during the daytime and higher pressure during the nighttime. The distribution of thermal pressure around the bin circumference wasnon-uniform during the daytime hours and was uniformduring the nighttime hours. Thethermal pressure per unit decline in wall temperature didnot vary significantly (P<0.05) around the bin cir cumference during either the daytime or the nighttime hours. The average thermal pressure increment was 114 Pa/?C for arange ofbin wall temperature from -11 ?Cto -29 ?C.
