This paper demonstrates how system identification techniques can be
successfully applied to a soil–structure interaction system using the
earthquake response data. The parameters identified are the shear moduli
of several near-field soil regions and Young’s moduli of the shell
sections of the structure. The soil–structure interaction system is
modeled by the finite element method combined with the infinite element
formulation for the unbounded layered soil medium. The simulated
earthquake responses using the identified parameters are shown to be in
excellent agreement with the observed response data. Prediction of the
responses is also carried out for a larger earthquake event using the
identified parameters as the initial properties in the equivalent
linearization procedure. It has been found that the predicted responses
are also compared very well with the measured responses.
