Abstract
The nonstationary response of an elastic circular cylindrical tank, partially filled with liquid, to lateral earthquake excitation is investigated by modeling the earthquake acceleration as an amplitude modulated nonwhite random process. The differential equation governing the displacement of the tank wall due to the finite amplitude liquid surface oscillation is solved directly and the results are compared with those obtained by Galerkin's method reported previously. A fairly good agreement is found between the previous and the present results.
