Kinematic soil-structure interaction (SSI) results from the incoherent nature of ground motions, which causes the motions of foundation slabs to generally be reduced from those in the free-field at high frequencies. We compare two models of kinematic SSI utilized in engineering practice: one based on finite element analysis and the second based on a semi-empirical approach. Predictions from both approaches are compared for two well-instrumented structures to observed transfer functions. The results show (1) the two models produce very similar transfer function estimates and (2) the model predictions are generally consistent with observations.
