Abstract
This research deals with effects on foundation response produced by stress waves propagating from underlying soils. A circular footing was located at the surface and at different depths of burial and a transient load was applied to the footings through the underlying soils. Stress-time and strain-time histories were recorded through embedded gages. These records were correlated with acceleration-time records of the input load and foundation response to provide a comprehensive picture of stresses and strains in a soil mass subjected to earthquake type loading. The investigation also includes some static and dynamic experiments, conducted using a thin layer of compressible material buried at depths of one radius below the footing.
