000021971 520__ $$2eng$$aThe dynamic analysis of a historic water is attempted taking into consideration the fluid-structure-soil interaction. The water tank is cylindrical with a concentric manhole and rests on a relatively flexible structure and a ring of surface foundations. A FEM model of the tower and the structure is developed preserving all the details of the original structure. Extensive parametric studies, undertaken in the context of this work, resulted in a discrete model for the hollow water tank along the lines of the convective-impulsive mass concept. Related non-dimensional charts are shown herein. In addition, a discrete spring-mass-damper model is used for the simulation of soil-structure interaction. The full model of the water tower is subjected to seismic excitation and the results obtained by this rigorous numerical model are compared to other simplified approaches.
