000013743 520__ $$2eng$$aThe time domain seismic response of a representative liquefied natural gas (LNG) tank isolated at its base level with rubber bearings is investigated. The problem is solved numerically by means of a detailed finite element model, taking into account fluid-structure interaction effects. Two types of seismic isolation systems are investigated: lead core rubber bearings and linear rubber bearings combined with non linear viscous dumpers. Both these systems are characterized by strong energy dissipation mechanisms. The isolation systems are modeled as non-linear spring-dashpot elements with properties calculated on the basis of experimental data obtained from the literature. The seismic excitation considered is an artificial accelerogram compatible with the Eurocode 8 provisions. Results concerning base shear force, sloshing vertical displacement and deflection of the inner steel container are presented. In order to measure the effectiveness of the isolation systems, percentage reductions of the peak response of all mentioned quantities are calculated using the nonisolated tank as reference.
