000021573 520__ $$2eng$$aLiquid storage tanks are important components of liquid transmission and distribution systems and should be properly designed to withstand dynamic loadings which can take several forms. One of them is the investigation of tanks subjected to a seismic excitation. During seismic activity, a specific interaction between the tank and the liquid occurs. It is expressed as a vibration of the tank, its walls and contained liquid. The impulsive (lower) portion of the liquid moves in unison with the structure while the convective (upper) portion represents the free surface moving against a wall which results in a sloshing effect. The procedure for the design of tank-liquid systems for earthquake resistance is covered in various international and national standards. The paper deals with the seismic analysis of the aboveground vertical liquid storage tanks of circular cross section with different slenderness parameters (from broad to tall tanks) intended to compute the dynamic properties (natural frequencies and respective modes of oscillation) and the response of the flexible tank – liquid system to seismic loading using the response spectrum method. The paper also focuses on the comparison of dynamic properties of the tank-liquid system when it is resting on a rigid or flexible foundation. For tanks supported on softer soils, the dynamic response may be significantly different from those supported on rigid foundations. In addition to the seismic analysis, the paper is dedicated to comparing the acquired results from analyses computed by FE method (in ANSYS Multiphysics) with the results from analytical calculations of a tank containing liquid introduced in Eurocode 8.
