In RLSC, the effect of input loss caused by the embedding foundation is calculated using the amplification of the surface strata, GS, and the soil–structure interaction factor (SSI-factor) β . We previously showed that the evaluation of the embedding effect of the foundation in RLSC is conservative, particularly in a short period range less than the first period of the surface strata. To improve this overestimate of the foundation input motion, a SSI-factor β considering the second vibration mode of the surface strata is incorporated and new formulas are proposed. The response acceleration spectra obtained by the proposed method are in good agreement with those of rigorous analysis.
