Abstract

A number of parameters to assess instrumental intensity in either the frequency or in the time domain have been proposed in the past. These can be used for the scaling of natural accelerograms to define the seismic input for nonlinear analysis, or for damage potential estimations. This paper evaluates the degree of correlation between different instrumental intensity measures using a subset of a European database of natural accelerograms of strong ground motion. The degree of correlation is critically examined in terms of local site-conditions and faulting mechanism. A set of predictive equations are proposed to estimate either Arias Intensity or Cumulative absolute velocity as a function of Housner Intensity
