Our past numerical analysis of the response of an existing seismic isolation building to actual earthquakes has confirmed the following; i) A lumped mass model can be used to estimate the response of the upper structure and the deformation of the isolation device, as the dynamic behavior of the base isolated building is dominated by the first vibration mode. ii) A finite element model (FEM) more accurately simulates the higher modes and is recommended when the effect of high-frequency mode is significant. The past study was carried out to analyze the behavior observed during medium earthquakes where the relative displacement of the isolation device was less than the yielding displacement of the damper. In this study, we use the same numerical methods, which have been demonstrated to be useful in the past analysis for medium earthquakes, to study the behavior of the existing four-story building during a hypothetical large earthquake.
