The purpose of this study is to consider site effect in order to estimate Soil-Structure and attenuation parameters with a greater degree of reliability. Site amplification is calculated by proposed Nakamura (H/V ratio). The site amplifications using acceleration motion were compared at several sites. The result can be used for the study of site classification and removal of the site amplification effects.
