Effectiveness of soil-structure interaction in earthquake response reduction of buildings is studied by earthquake response analyses using representative ground motion record of recent domestic or foreign big earthquakes, namely, the 1995 Hyogo-ken Nanbu earthquake, the 1999 Kocaeli earthquake in Turkey, the 1999 chi-chi earthquake in Taiwan, the 2000 Tottori-ken Seibu earthquake and the 2001 Geiyo earthquake. In the analyses, simple sway-rocking models are used and non-linearity of buildings is considered. It is assumed that buildings are on the elastic uniform soft soil. From the analyses, it is pointed out that the damage reduction effects by soil-structure interaction greatly depend on the ground motion characteristics, number of stories and seismic performance of buildings. Consequently, it is very important to consider soil-structure interaction to evaluate the earthquake damage of buildings properly.
