Abstract
This paper has been written within a research framework investigating the destructive potential of seismic
events. The elastic response spectra seem insufficient to explain the behaviour of structures subject to large
earthquakes in which they experience extensive plastic deformations. Recent works emphasise that there were
many difficulties in the definition of a single pararneter linked to the destl-uctive potential of an earthquake. In
this work a study on the effect of frequency content on structural damage has been carried out. The behaviour
of two different elastoplastic oscillators has been analysed, considering several artificial earthquakes. The results
obtained suggest a method for evaluating the destructive seismic potential of an earthquake through the
response spectra ad the frequency content of the signal. and through the mechai~ical characteristics of the
structures within the analysed area.
