000010980 520__ $$2eng$$aNonlinear behavior of soil response is discussed using the strong-motion records from recent Japanese earthquakes. During the 2004 Niigata-ken-chuetsu (MJ 6.8), the 2007 Noto-hanto (MJ 6.9), and the 2007 Niigata-ken-chuetsu-oki (MJ 6.8) earthquakes, large amplitude strong-motion records with peak ground velocity of about 100 cm/s are observed on soft soil sites. The strain level developed in surface soils and shear modulus ratio of soils are estimated from the records by a simple method. The estimated shear modulus ratios are 0.8 to 1.0, 0.4 to 0.6 and 0.2 to 0.3 at strain levels of 0.01%, 0.1% and 1%, respectively. The dependency is consistent with the previous laboratory data, suggesting the validity of the soil response analysis based on the laboratory data.
