Features of static calculation of tanks were revealed. Physical and mechanical properties of the material and geometric parameters of the vertical tank were determined. A full-size finite element model of a filled vertical steel tank has been developed. The calculation of the filled vertical steel tank was performed. The values of frequencies and periods of natural oscillations were obtained. Finite element method that was implemented in LIRA-multifunctional software package allows to design and calculate the structures for various purposes. © 2022 The Authors. Published by ELSEVIER B.V.

Introduction Tanks are made of the following materials: steel, aluminium, synthetic materials, reinforced concrete and others by American Petroleum Institute (2003). According to the form of tanks are divided into vertical, horizontal, isothermal, spherical, rectangular. As a result of generalization of data on consequences of earthquakes on reservoirs, it is possible to draw a conclusion that the main reasons of their accidents at seismic influences are by American Water Works Association (2003): failure of the floating roof and damage to the floating roof stairs; fracture of a stationary roof as a result of impact of a wave of fluctuating liquid; loss of stability of the upper part of the body; plastic deformations of the shell of the tank in the lower part (the so-called "elephant's foot") from the action of 1st Virtual International Conference “In service Damage of Materials: Diagnostics and Prediction” Simulation of the stress-strain state of a cylindrical tank under the action of forced oscillations Mykhailo Hud* Ternopil Ivan Puluj National Technical University, Faculty of Engineering of Machines, Structures and Technologies, Ternopil, Ukraine Abstract The paper considers the classification of steel cylindrical tanks failure from the action of seismic loads.
