The paper presents a simple and sufficiently accurate method for estimating the seismic response of cylindrical liquid storage tanks. The method uses a mechanical model that incorporates tank wall deformability, derived from finite element analysis of the liquid‑shell system, with parameters tabulated in charts and illustrated by numerical examples to predict maximum seismic response via response spectrum. Comparison with the exact solution confirms the method’s validity.
A simple and sufficiently accurate method for estimation the seismic response of cylindrical liquid storage tanks is presented. A mechanical model, which takes into account the deformability of the tank wall is examined; it is based on the results of a finite element analysis of the liquid-shell system. The parameters of such a model are displayed in charts that facilitate the calculations of the effective masses, their centers of gravity, and the periods of vibrations. Detailed numerical examples are presented to illustrate the applicability of this model in predicting the maximum seismic response by means of response spectrum. Comparison with the exact solution of the problem confirms the validity of the method.
