The specification of the earthquake input for the linear and nonlinear analysis of the structure-foundation problem is usually done by prescribing the base motion. Most commonly the actual analysis is carried out in terms of displacement relative to this base movement. If realistic boundary conditions need to be specified because of the infinite extent of the foundation, this “conventional” procedure is not applicable. An alternative is therefore suggested by specifying the motion in terms of the incoming seismic wave, leading to a logical and simple problem formulation.
