exhibits the compression of the dynamic and static pressure as the silo is
full with constant diameter the height from ( 16m – 20m – 30m – 60m ) and for different h/d ratios = (3-4-
5),(1.6-3) and (0.8-3) respectively. As shown in these figures, the dynamic pressure is equal to (3-5) ; (1.5 -3)
and (1.6-2) times the filling pressures respectively . In the squat (Large diameter silos), the max dynamic
pressure occurs at 0.65h from the silo top and equals 2 times the filling pressure.
