Seismic isolation systems exhibit non-linear inelastic behavior, which can be sufficiently well represented by a bilinear model. However, simplified linear elastic analysis is often used, at least at the preliminary design and analysis phases of seismically isolated buildings. Therefore, it is very important to investigate the appropriateness of using linearized models by comparing their computed responses with those of the more accurate bilinear models. In particular, this research work investigates whether linearized models are suitable for the analysis of seismically isolated buildings, considering the maximum relative displacements at the isolation level, the peak interstory deflections and the absolute floor accelerations. A number of numerical simulations and parametric studies have been performed, using specially-developed software, to obtain an insight on the suitability of using equivalent linear elastic models to simulate seismically isolated buildings, and identify how that is affected by certain structural parameters and earthquake characteristics.
