Underground storage tanks and containers from plastic material
(Wydawnictwa AGH, 2005) Vojtasik, Karel; Aldorf, Josef; Hrubešová, Eva
The contribution describes an evaluation method of an external wall of underground storage tanks and containers. The wall are of a sandwich - composite construction. The composite is formed by plastic tabular or wall elements and layers of concrete. In some cases, concrete is supported by a steel mesh. The evaluation method is based on the determination parameters of the composite and the straining coefficient of material forming the composite. These are determined based on a condition regarding coequal dislocations on internal borders between the layers - materials of the composite.
