6.16. A tall cylindrical silo carrying flour is to be supported by a 1.5 m wide ring beam that can be designed as a continuous foundation. The inner and outer

diameters of the ring are 10 m and 13 m,respectively. The soil at the site is entirely sand ( = 35°, y 19 kN/m2) and the ring beam is placed on the ground with D 0. Determine the maximum silo load that can be carried by the ring beam, assuming that the entire load is transferred to the ground through the ring beam.
