000013566 520__ $$2eng$$aBase Isolation System (BIS) is a very effective strategy for reducing the effects of earthquakes on building structures. The classical Response Spectrum Method (RSM) continues to be the most common approach for the design of base-isolated buildings. This paper offers a new strategy of seismic analysis and design for such structures in conjunction with the RSM. The main advantages of the proposed approach are: first, reduced computational effort with respect to an exact complex-valued modal analysis, which is obtained through a twostage transformation of coordinates, both involving real-valued eigenproblems; second, accurate representation of the damping, which is pursued by consistently defining different viscous damping ratios for the modes of vibration of the coupled dynamic system made of superstructure and BIS; third, ease of use, since a convenient reinterpretation of the combination coefficients leads to a novel Damping-Adjusted Combination (DAC) rule, in which just a single response spectrum is required for the reference value of the viscous damping ratio.
