“…Also, the effect of soil interaction on the seismic response of elevated water tanks has been studied by many authors [7][8][9]12], and [13]. However, most of these studies focused on the effect of fluid interaction on cylindrical ground water tanks; only a small number of them have concentrated on the evaluating the effect of fluid interaction on the seismic response behavior of elevated water tanks.…”

“…Most of these studies used a simplified fluid interaction model [14][15][16][17][18], however, a few of them used the finite element method as well. Livaoglu and Dogangun [7] proposed a simple analytical procedure for seismic analysis of fluid-elevated tank-foundation-soil systems, and they used this approximation in selected tanks. Haroun and Ellaithy [19] developed a model which considers fluid sloshing modes and assesses the effect of tank wall flexibility on the earthquake response of the elevated tanks.…”

The dynamic behavior of a liquid storage tank as a special structure differs from that of general structures. Important structures of cylindrical shape are used to store vital products, such as water and petroleum products, for cities and industrial facilities. Damage to these structures during a strong ground motion may lead to fire or other hazardous events. Liquid storage tanks are lifeline structures and strategically very important, since they have vital use in industries and nuclear power plants. In this research, an example reinforced concrete (RC) elevated water tank, with 900 cubic meters capacity, is studied under three pairs of earthquake records and analyzed in time history by using mechanical and finite element modeling techniques. The liquid mass of the tank is modeled as lumped masses known as sloshing mass, impulsive mass and rigid mass. The corresponding stiffness constants associated with these lumped masses are worked out depending upon the properties of the tank wall and liquid mass. Tank responses including base shear, overturning moment, tank displacement, and sloshing displacement under these three pairs of earthquake records are calculated, and then the results are compared and contrasted. Results show that the system responses are highly influenced by the structural parameters and the earthquake characteristics, such as frequency content.

Dynamic analysis of liquid storage tanks is one of interesting subjects in the earthquake engineering. In the present paper, the staggered displacement method is utilized for analysing concrete storage tanks. In the proposed method, surface sloshing of the liquid do main is considered in addition to the effect of impulsive component of the liquid on the structure response. Also, different damp ing coefficients are applied on the various co mponents of the liquid. Foundation is assumed to be rig id and an artificial dynamic load as well as a real ground mot ion record are used to analyse the tank-liquid coupled system in t ime domain. The resulted response is co mpared with those obtained from the co mmercial software. It is found that the convective term affects responses extensively and must be considered in seismic safety analysis of storage tanks.

This paper presents the seismic response analysis of a cylindrical container made of laminated composite. The analytical homogenization is used for calculation of the material properties of unidirectional fiber‐reinforced composite layer. Constitutive relations for laminate within the classical laminate theory are considered. Effective modulus of elasticity is obtained and put into a calculation of internal forces of the laminated composite cylindrical tank. The seismic analysis of liquid storage facilities has to have different approaches as the analysis of typical structures. Because of an earthquake, the hydrodynamic impulsive and convective pressures are generated in addition to hydrostatic pressure. The solved liquid‐filled container made of the laminated composite was situated for the region of Slovak Republic and was analyzed in respect of Eurocode 8 recommendations.
