The effects of various structural parameters and ground motion characteristics on the seismic response of base-isolated multistory structures are investigated. Results are used to develop two simplified analysis methods for practical design. The first method, which is called the code-type approach, can be used to accurately estimate the inertia forces, not only at the level of the isolation devices, but throughout the height of the multistory structure. It is recommended for use as a preliminary design tool or even a final design tool for simple base-isolated multistory structures. The second procedure, which is based on the component mode synthesis method, is suggested for final design purposes of more complex base-isolated multistory structures. This method enables the designer to evaluate the effects of the isolation devices on the contribution of each mode of vibration to the total response of the structure.
