Annotation: The paper deals with the basic questions of increasing the reliability and ecological safety of vertical cylindrical tanks. One of the ways of decreasing a risk is an application of two-walled tanks. A critical unit of such tanks is the one of linking walls and the bottom. A stress-deformed state of such units is influenced by a number of factors. The most important factors are geometrical parameters, constructive solutions, interaction with the bottom, non-uniformity of settling. Among the peculiarities of a chime unit operation we should mention the influence of different loads, namely, static, dynamic, cyclic ones corresponding to normal and emergency modes of operation. There are considered the methods of designing chime units. A numerical model of a chime unit is given in the form of volumetric final elements with a detailed layer-wise layout of walls and bottom fringes. There are considered two variants of constructive decisions, first, every walls rests on its own bottom; second, walls rest on a single sheet. Liquid pressure load is taken as corresponding to normal and emergency operation when the liquid pours out between the walls. The effort values have been obtained, a cross-effect of the walls and the bottom has been analyzed.
Keywords: pipe package, shape factor, stack.
