“…The rectangular liquid storage container is of great significance due to its extensive applications in energy storage and transportation, ocean engineering, water supply and sewage treatment as well as nuclear power plant. Serious structural failure for liquid storage containers may occur due to the additional forces acting on the container wall caused by liquid oscillation 1 – 3 . Therefore, it is of great benefit to study liquid-structure interaction of systems, which can help improve the system safety under external seismic loads and reduce the probability of structure failure 4 – 7 .…”

An equivalent analytical model of sloshing in a two-dimensional (2-D) rigid rectangular container equipped with multiple vertical baffles is presented. Firstly, according to the subdomain partition approach, the total liquid domain is partitioned into subdomains with the pure interface and boundary conditions. The separation of variables is utilized to achieve the velocity potential for subdomains. Then, sloshing characteristics are solved according to continuity and free surface conditions. According to the mode orthogonality of sloshing, the governing motion equation for sloshing under horizontal excitation is given by introducing generalized time coordinates. Besides, by producing the same hydrodynamic shear and overturning moment as those from the original container-liquid-baffle system, a mass-spring analytical model of the continuous liquid sloshing is established. The equivalent masses and corresponding locations are presented in the model. The feasibility of the present approach is verified by conducting comparative investigations. Finally, by utilizing normalized equivalent model parameters, the sloshing behaviors of the baffled container are investigated regarding baffle positions and heights as well as the liquid height, respectively.

Tanks for the storage of oil and gas play a special role in the oil and gas industry. During the construction and design of such structures in difficult geological conditions, increased attention is paid to their safe operation. The combined manifestation of seismic impacts and the presence of permafrost can pose an increased danger. The article presents an analysis of the various components of an oil and gas storage system. A comparative analysis of the seismic resistance of storage tanks was carried out, taking into account the presence of a thawed permafrost base in the base. It is shown that during thawing, the permafrost base can greatly affect the seismic resistance of the structure.
