Seismic Analysis of Liquid Storage Structures sing Eulerian Formulation

In this paper the liquid sloshing effects in rectangular liquid stroage structures under earthquake loadings are studied. The study focuses on the investigation of the effect of the flexibility of the stroage wall. The storage structure is modelled using beam elements. The motion of the liquid is expressed by the Laplace equation. The equation of motion is formulated including the coupling between the wall motion and the sloshing motion. Seismic analyses have been carried out utilizing the response spectra method.
