EXperimental Assessment and Modelling of ground motion spatial variability for performance based seismic risk assessment of industrial plants and INfrastructures

Abstract:

The integrity of critical facilities and networks during an earthquake is a vital element for the sustainable development of societies and environments. It is now recognized that the spatial variation of seismic ground motion affects the dynamic response of extended and multi-supported structures such as bridges, embedded galleries, pipelines and more generally on infrastructure networks or industrial plants comprising several adjacent buildings. However, this variability at local and regional scales is generally not accounted for in current seismic risk and loss assessment. This project proposes a multi-disciplinary approach involving synthesis of geophysical and in-situ experimental data along with intensive numerical simulations and stochastic models to be integrated into the full risk assessment chain. The outcome of this project will allow for a more accurate evaluation the vulnerability and resilience of urban systems and infrastructures exposed to spatial seismic hazard.
