The seismic analysis of fluid-coupled concentric cylindrical shells is reviewed. A coupled fluid-structure finite element method which considers the sloshing effect is then developed for the seismic analysis of liquid-filled systems with internal components. The theoretical development of the mixed finite element formulation is also included. The resulting fluid-structure interaction algorithm has been integrated into the computer code FLUSTR II and the seismic analysis of liquid-filled tanks with an eccentric core barrel is performed. Numerical results show the method yields accurate solutions with large increases in efficiency.
