DURATION AND ENERGY CHARACTERISTICS OF GREEK STRONG MOTION RECORDS

An ensemble of 201 Greek strong motion components is analysed and the respective duration and instrumental energy characteristics are determined. A comparative study of these characteristics and their correlation with (i) Modified Mercalli Intensity measures and (ii) peak response and input energy measures of SDOF systems, reveal the most suitable ones which can serve as indicators of the damage potential of the ground motion. Predictive relations of these measures, valid for the Greek tectonic region, are also provided.
