Summary

This paper examines the nature of the response of strongly yielding systems to stochastic excitation. In particular, systems which can be modeled using a combination of linear elastic and Coulomb slip elements are considered. It is shown that the displacement response of such systems cannot, in general, be accurately predicted using linearization techniques. As an alternative, a slip or yield increment analysis approach is proposed. It is further shown that the nature of the response of strongly yielding systems is strongly dependent upon the shape of the low frequency portion of the excitation spectrum.
