In this paper, we research a conventional evaluation method of soil springs in the dynamic soil-structure interaction analysis of buildings with embedment foundations. First of all, the bottom element and the side elements are decomposed from the embedment foundation and the dynamic interaction characteristics that each element possesses are examined. The estimation method developed by WEN and Fukuwa(2006) are applied to this examination. Based on the above results, it is mentioned that the soil spring of the embedment foundation which is composed with the impedance of both side and bottom elements is overestimated. Finally, we discuss impedance evaluation methods in the limit strength method and the sway-rocking model with embedment.
