IGCP Project 414: Realistic Modeling of Seismic Input for Megacities and Large Urban Areas

摘要: The project addresses the problem of pre-disaster orientation: hazard prediction, risk assessment, and mapping, in connection with seismic activity maninduced vibrations. definition realistic input can be obtained from computation a wide set time histories spectral information, corresponding to possible seismotectonic scenarios for different source structural models. availability numerical simulations enables us estimate amplification effects complex structures exploiting available geotechnical, lithological, geophysical parameters, topography medium, tectonic, historical, palaeoseismological data, modeling ground motion is very important base knowledge preparation groundshaking that represent valid economic tool microzonation. This fruitfully used by civil engineers design new seismo-resistant constructions reinforcement existing built environment, and, therefore, supplies particularly powerful prevention aspects Civil Defense.
