In soil-structure interaction problem, dynamic impedance function and foundation input motion (FIM) is fundamental physical properties. We carried out an axisymmetric finite element method (AX-FEM) analysis to verify the accuracy of FIM between "Response and Limit Strength Calculation (RLSC)" and AX-FEM. The acceleration response spectrum (ARS) obtained by RLSC almost envelops those obtained by AX-FEM in the range of the whole periods. Therefore, it can be said that the evaluation of the embedding effect in RLSC is conservative, particularly in a short period range. Also, it is observed that the spectrum at the foundation bed of the free field computed by SHAKE is similar to FIM, but the former response is underestimated in specific period ranges. Furthermore, it is shown that presentation of the numerical tables of transfer function of FIM is useful in practical design through comparison ARS of multi-layered soil model with that of equivalent two-layered soil model by RLSC.
