Abstract

This study investigates the vertical responses of seismically isolated buildings by considering the dynamic soil-structure-interaction (SSI) and the vibration of the long-span beam. We first construct a two-dimensional moment-resisting frame model by simultaneously considering the beam vibration and the SSI for a base isolated seven-story building by comparing observation records. As a practical application of vertical response analysis, we tested base-fixed frame models with the equivalently added damping to incorporate the SSI effect. The coupling effects with SSI can be adequately evaluated by adding a damping factor to columns when the frequency ratio to multi-mass model is less than 0.8.
