The procedure is aimed to calibrate a single-degree-of freedom (SDOF) model capable to simulate the mechanical response of lead-core bearing device for passive seismic isolation. The identification is based on data obtained by finite element simulation. An accurate finite element model is built. All components of the bearing device: lead-core, rubber layers and steel shims are discretely modeled. The lead-core bearing device is seen as a multiple component system. Constitutive laws are defined on the meso-scale for all materials: lead (-core), rubber, steel. Furthermore a typical identification test is simulated to obtain the shear stressshear strain relationship which characterizes the response of the lead-core bearing device. In the SDOF model describing the response of the bearing device on the macro-scale, a damage variable is introduced to account for mechanical damage accumulated in the lead-core.
