Effect of settlement of foundations on the failure risk of the bottom of cylindrical steel vertical tanks for liquids

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

A system consists of lifted steel tank and four assembly supports with variable assembly conditions

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

Reliability Analysis Of Thin-Walled Cylindrical Shells

Abstract

The subject of the article is the verification of the reliability of thin-walled rotationally symmetric cylindrical shells, using probabilistic approaches. Internal forces and stress of the shell are analysed assuming a membrane action. Material and geometric characteristics of the steel shell are considered as random variables. The reliability index is evaluated using the Latin Hypercube Sampling method. The results of the reliability analysis are derived in a general form, so that they may be useful for assessing the reliability of tanks and pipes.
