摘要

Assessing local site effects reliably is one of the crucial aspects of seismic hazard,which usually cause amplification of ground motions and results in increasing thedamage potential of a large earthquake. This phenomenon has been recognized forsome time (e.g., Milne, 1898; Takahashi and Hirano, 1941; Gutenberg, 1957). Themethods used to determine the site response can be categorized into two majorgroups, the analytical (theoretical) and the empirical methods. The analytical cal-culation of the site response, mainly based on inversion techniques, requires a verygood knowledge of the geotechnical parameters to constrain the results. Empiricalmethods are somehow more effective in the sense that they are based on calculat-ing the frequency spectrum directly from the recorded ground motion.
