The structure under consideration is an elastic cylindrical liquid storage tank attached to a rigid base slab. The tank is filled to an arbitrary depth with an inviscid, incompressible liquid. A finite element analysis is presented for the free vibrations of the coupled system, permitting determination of natural frequencies and associated mode shapes. The response of the partially-filled tank to artificial earthquake excitation is also determined through use of finite elements. Examples, together with program listing, are offered.
