The impact of non-linear soil behavior on site response may be described by the non-linear to linear site response ratio RSRNL introduced in Régnier et al. (2013). This ratio most often exhibits a typical shape with an amplitude above one below a site-specific frequency fNL, and an amplitude below one beyond fNL. This paper presents an...

We use two different purely empirical approaches to estimate the non-linear transfer function betweena reference rock and a sedimentary site from recordings of weak ground motions and site-conditionproxies (SCPs). The modulus of the linear transfer function is first computed from weak motions andthen modulated with a correction to consider...

This contribution presents a statistical analysis of the non-linear behavior that can be detected on strong motionrecordings obtained on thick Japanese sedimentary sites from the KiK-net and K-NET networks, and presents acomparison with other site types, with thinner deposits and/or higher fundamental frequencies. The non-linear effects are...
