An analytical mechanical model for cylindrical tanks is presented taking into consideration the effect of rigid base rocking motion and lateral translation. The liquid is assumed to be
homogeneous, inviscid, and
incompressible. Only rigid tanks were studied. Analytical expressions for the parameters of the model are given, and numerical values of these parameters are displayed in charts. The analysis includes both impulsive and connective pressures. The model can be used to evaluate the dynamic response of a rigid cylindrical tank subjected to earthquake loading with and without rigid base rocking motion.
