Abstract
Elastic and inelastic spectra are derived, based on a set of records representative
of Greek earthquakes. For the selection of the dataset, criteria of magnitude,
distance and PGA are used. Recently developed techniques are used to correct
and filter the noise and other errors in the records. Based on available
geotechnical information, a classification of the dataset into three soil categories,
compatible to the 2004 Eurocode 8 (EC8) provisions, is made. After appropriate
scaling, mean elastic and inelastic spectra are computed both irrespective of, as
well as for, each soil condition, and comparisons with the EC8 design spectra are
made.
Keywords: elastic spectra, inelastic spectra, strong motion accelerograms, filtering, soil classification, Eurocode 8.
1 Introduction
Elastic and inelastic spectra, either of pseudoacceleration or displacement, play a
key role in modern Earthquake Engineering practice. Especially, displacement
spectra form the basis of the recently developed displacement-based design and
pushover analysis procedures and their adoption by seismic codes is currently
underway. For the evaluation of such spectra, careful selection and proper
processing of representative strong motion records are of paramount importance.
Keywords
elastic spectra, inelastic spectra, strong motion accelerograms, filtering, soil classification, Eurocode 8.
