The Soil's Eye View of Soil-Structure Interaction in a Dense Urban Environment.

  • How does the seismic response of one building propogate effects through the soil to affect the response of a nearby building?

  • What characteristics are relevant with respect to the soil, the superstructure (above-ground structure), and foundation (below-ground structure)?

  • What are the implications of this research on the practice of structural and geotechnical engineers?

  • How can the use of centrifuges in geotechnical engineering be more broadly applied?

  • What are the learning experiences of the students who are involved in the research?


This project focuses on documenting and understanding the seismic performance of soil-foundation-structure systems within dense urban environments. A high priority NEES research topic, soil-foundation-structure interaction effects in low to mid-rise buildings are poorly understood. [more]

Recent Testing:
Two Isolated Structures on dry sand were tested July 13, 2009 to Aug. 14, 2009 at the University of California, Davis research site. [more]

Next testing cycle planned for November, 2009.
