Abstract : A nuclear power station is normally composed of several buildings some of which have their own separate foundation base mat or footing. When subjected to seismic excitation the response of these buildings is coupled through soil structure interaction effects. Two basic methods are commonly available to solve the structure-to-structure interaction effects: the direct finite element method as implemented by FLUSH, and the lumped parameter finite element approach. A comparative study between the elastic half space solution as computed by the MODAN code and the FLUSH code for the AGR island on a single base mat was reported in 5 and good agreement was obtained in the computed structural response.
