system model are reviewed. The procedures used in the SSI analysis to account for effects of adjacent structures, if any, on structural response are reviewed. To perform a seismic analysis for an SSI system, it may be necessary to have well- defined excitation or forcing functions applied at the model boundaries to simulate the design ground motion. It is therefore required in such cases to generate an excitation system acting at the boundaries such that the response motion of the soil media at the plant site in the free field is identical to the design ground motion. The procedures and theories for regeneration of such an excitation system are reviewed.
