ABSTRACT
A unified theoretical model for the dynamic behaviour of a two-dimensional coupled fluid–solid system is presented. The fluid-solid interface is considered as an infinite number of fluid and solid contact dot-pairs. On the fluid-solid interface each dot-pair can be in a slip or a non-slip condition. The Finite Element Method is applied to the model and the dynamic governing equation is solved using the Wilson-? method. The model demonstrates that elastic modeling of structural elements makes a significant difference to the predicted effect of seismic excitation on water-retaining structures.
