In order to perform time history earthquake response analyses in consideration of both the dynamic soil-structure interaction and the nonlinear behavior of the structure, it is important to transform the soil impedance in the frequency domain to an impulse response in the time domain. The author have studied the time domain evaluation of soil impedance, and proposed a transform method. In this paper, deeply embedded structures in the layered soil were investigated based on embedded SR model. The strong frequency dependent soil impedance was transformed to the impulse response, and earthquake response analyses were carried out in the time domain. The efficacy of the proposed method was confirmed through these studies.
