Non-linear attenuation effects on soils dynamic response evaluation

Abstract

The object of this paper is to estimate the structural attenuation in geological site materials with the aid of the non-linear magnification functions maximum values decreasing. Using a non-linear one-degree-of-freedom model (NKV model) with material functions in terms of the strain levels, by numerical non-linear simulation one put into evidence the attenuation capacity of the site geological materials neglected by linear calculus.
