In the modeling of dynamic soil-foundation-structure interaction, a key component is an accurate determination of the dynamic foundation impedance matrix for a particular site. In this paper, the feasibility and problems in inverting experimental test measurements to obtain the lateral-rocking impedance functions are discussed. It is shown mathematically that the success of the experimental method depends sensitively on the structural and testing configuration employed. A numerical simulation of the underlying issues is provided as illustration.
