TLDR
In this article, the authors propose to specify the motion of the base motion in terms of the incoming seismic wave, leading to a logical and simple problem formulation, where realistic boundary conditions need to be specified because of the infinite extent of the foundation.Abstract:
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.read more

On the seismic response of shallow-buried rectangular structures
TL;DR: In this article, the authors investigated the applicability limits of simplified analyses of non-linear static soil-structure interaction analysis and showed that shallow-buried rectangular structures are strongly affected by nonlinear frictional effects at the soilstructure interface.
