Abstract

This paper describes a geotechnical centrifuge test that is part of a study investigating soil-foundation-structure interaction effects in dense urban environments. Two prototypical structures, a three-story building on spread footings and a nine-story building on a three-story basement, are located sufficiently far apart to be considered isolated from each other. The results show that kinematic soil-foundation-structure interaction is important for structures founded on deep, stiff basements. Additionally, acceleration amplification factors from the ground to roof levels of these buildings are under two and during intense motions, more than 50% of the roof drift of the shallow spread footing-supported structure is attributed to foundation movements. For lower intensity motions, the foundation movements only contribute approximately 20% of the roof drift.
