Description ERST evaluates the elasto-hydrodynamic response of submerged oil storage tanks to earthquake ground motion. A hybrid finite element method is used, in which the tank structure, the interior fluids, and the near field of the exterior water region are discretized into a ring-shaped mesh network. The tank structure is rigidly attached to the ocean floor. The tank is axisymmetric, has a flexible wall and/or roof, and is filled with two different layers of fluid. Both the dynamic and the static responses are evaluated.
