Abstract

In recent years, considerable research and development in all fields of earthquake engineering was conducted. In particular, the reassessment of the seismic risk in countries with former low seismicity has brought about considerable changes in civil engineering.

In general, monitoring of soil–structure interaction effects is something that needs to be intensified in the future. As there is very poor current practice on this topic, this article should indicate a perspective view on possible applications.

For a realistic seismic assessment of structures, it is often necessary to use methodologies that regard the influence of the subsoil on one hand and can assess the real bearing capacity of the structure on the other hand. These two major issues are discussed within this article. In the first part of this article, a brief overview of the theoretical methodology of soil–structure interaction techniques is given, which should cover the needs of realistic modeling in earthquake engineering. The second part should mainly describe an approach for the experimentally based seismic assessment of structures, demonstrated at a practical example. Finally, the last part of the article should give an overview of seismic effects in general.
