A circular tower grain silo is built on a concrete ring foundation (see cross-section below). The footing is founded at a depth of 0.9 m in a clay soil and is 1.1 m wide. The storage walls of the silo are 0.203 m thick and 22 m high, and are also made from concrete (take the unit weight of concrete = 22.8 kN/m³). The inside diameter of the tower is 9.14 m. The grain being stored in the tower silo has a unit weight of 8 kN/m³. The storage has a hemi-spherical concrete roof, which is 0.203 m thick and has the same internal and external diameters as the tower walls. The site has sedimentary rock 25 m below ground level. This is overlain by a clay stratum, which extends to the surface. The clay soil has a relatively strong, overconsolidated layer 'A' (approximately 6 m thick) overlying a normally consolidated clay layer 'B'. The water table occurs at ground level. In-situ vane and laboratory triaxial testing has indicated that the undrained shear strength Cu in each layer can be described using this equation: Cu = Cuo + .z (kPa), where Cuo is the undrained shear strength at the top of the layer (kPa), is the rate of strength increase with depth into the layer (kPa/m) and z is the depth from the top of the layer (m). For layer 'A' the values of cuo and are 100 and -13.33 respectively. For layer 'B' the values of Cuo andare 20 and 1.43 respectively. The unit weight of the clay is Y = 19 kN/m³.
