Geotechnical projects to preserve cultural heritage; Soil-structure interaction; Seismic hazard mitigation

The conservation of monuments and historic sites is one of the great challenges concerning the entire European territory. In addition to typical factors to deal with, such as cultural, technical, and economic aspects, mitigating the risk coming from geotechnical aspects is a crucial aspect. Among these risks, the seismic risk is one of the most important. The impact of a strong earthquake on an urban community can be reduced with timely and well-planned actions. Assessing the seismic behaviour of structures and the monuments inside them requires detailed knowledge of the effects of the soil in seismic wave filtering (LSR: local site response; DSSI: dynamic soil-structure interaction). The seismic input change greatly from the bedrock to the foundation level. In addition, DSSI plays an even more decisive role when sliding and uplift occur at the soil-foundation interface.
