CYLINDRICAL WATER RESERVOIR.

Reservoirs, which can have different floor plans, are among the most important civil engineering structures used in various branches of industry, in agriculture, in water management. They can be made from the different materials, but the most common are reinforced concrete or steel. All these structures are placed on the ground, the composition of which depends on the location of such a structure. In addition to these surface tanks there are also semi-recessed or fully recessed ones. Any of such tanks must be designed to meet the requirements not only of investors, but also the basic requirements for the design of structures, valid in the countries concerned in the individual Eurocodes. Such structure must safely transfer the applied load to the foundations and subsequently to the ground mass so that it does not break. In some cases, even the slightest failure could lead to an environmental problem, where the fluid stored in the tank could flow into the subsoil. This paper deals with cylindrical reinforced concrete tanks serving as water reservoirs. These tanks will be assessed for the limit state for deflections. The reservoirs will be located either on a massif consisting of the same soil or on a layered subsoil. The first subsoil will be composed of clay, the second one will consist of layers of clay and gravel. Subsequently, the maximum deflections in the foundation joints on the individual tanks will be compared. A big danger could be caused by the uneven distribution of the soil layers, which could lead to uneven settling and this could cause cracks in the tank, or even an accident of the tank at all.
