This thesis presents an analysis of data from two soil-structure interaction field tests, one involving a deep foundation and the other a shallow foundation. The objective of this research is to use the field data to validate and inform models used by engineers. Soil-structure interaction fundamentals and background are first discussed. Field-test data was used in conjunction with a soil-structure system model to develop equations that can be used to determine stiffness and damping of a rigid pile foundation system subjected to forced vibration loading. The stiffness and damping characteristics are presented through complex-valued impedance functions. The equations were applied to field data; however the results were inconclusive due in part to the limited frequency range of the data used. Additionally, soil-foundation interface pressures are analyzed for a shallow foundation system. Analysis of the shallow foundation behavior indicated resonance of the field test structure and the corresponding pressure generation.
