Measurement and prediction of strong ground motion in Europe

The need for earthquake strong-motion data stems from the fact that demand is growing for safer equipment, buildings and systems under earthquake loading. This pressing need for greater reliability and quality assurance ranges from appliances to building components, bridges to power plants and dwellings, and from structural materials to building codes. This need is strongly felt by engineers and manufacturers alike, in both high and low seismicity areas of the European Community. At the same time, fast developing markets between European Community (EC) member states, combined with financial constraints on industry and governments, mandate efficient methods to find cost-effective ways to enhance earthquake safety and reduce liability. In this project over 1000 ground motions were retrieved, processed and analysed during earthquakes in the greater European area. Predictive formulae for earthquake loading of structures for use in Euro-Code-8 were made available to the scientific and engineering community. Also predictive attenuation laws were derived for horizontal and vertical peak ground accelerations as a function of source distance, magnitude and local soil conditions. Attenuation laws for spectral ordinates for both vertical and horizontal motions as a function of magnitude, source distance, structural period and local soil conditions were also formed.
