1 Introduction Vertical cylindrical steel tanks for the storage of liquids use different types of foundations. In such tanks, sometimes ground-layered foundations are used, and much more often, ring-shaped reinforced concrete foundations with compacted gravel-sand substrate inside these rings. During long-term operation of the tanks, the soil under the steel bottom of the tank undergoes permanent deformations in the form of vertical non-uniform settlement. This settlement can have different causes, but in each case, affects the state of stress and deformation in

1 Introduction Concrete liquid tanks seem to be rigid, heavy and insensitive to differential settlement. The practice shows, however, that tanks founded in the layered subsoil may be subjected to differential settlement, particularly if one on the layers is of low strength and low stiffness. The non-uniform distribution of stress transferred onto the ground strongly contributes to the increase in differential settlement, for example, stress under foundations of columns and walls are different from stress under bottom slab and stress under full chamber is

1 Introduction A cylindrical steel tank for liquid with a vertical axis and with the following parameters, V = 1,200 m 3 , H = 20 m, m = 38.85 t, was mounted. The shell of the tank consisted of 10 shell courses (segments) with respective thicknesses of 5 mm– courses from 1 to 4, 6 mm (courses 5–6), 7 mm (courses 7–8) and 8 mm (courses 9–10). During the assembly of each segment, the shell of the tank was stiffened on fragments of its lower edge using bowed (cambered) channels about 3.0-m long, to which connectors were welded. To mount the tank, four steel
