Abstract
There are many studies have indicated that nonlinear soil response will occur when strong ground motion wave shook surface soft soil layers. The nonlinear soil response has been a long controversial subject in seismology and earthquake engineering. A main obstacle to identifying this effect is that observed spectra are contaminated by source and path spectral contributions. In order to reduce the source and path effects, the horizontal-to- vertical (H/V) spectral ratio of a single surface station has become increasingly popular in studies of site effect. In this study, the horizontal-to- vertical spectral ratio method was applied to weak and strong motion records from the same dataset which used from Wen et al.1995.
