Operational agreement between the Directorate-General for Environmental Safety, Mining and Energy Resources - Ufficio Nazionale Minerario per gli Idrocarburi e le Georisorse (DGS-UNMIG) and RELUIS to carry out research activities and institutional support for the study of innovative approaches in relation to the issue of safety, including environmental, relating to the research and cultivation of hydrocarbons at sea.
Duration of activities 12 months 2017-2018
The objective of RELUIS within the SPOT project (Seismicity Potentially triggering Offshore and Tsunami) was the assessment of damage scenarios related to tsunami events through a large-scale approach. In particular, the vulnerability of residential buildings in masonry and reinforced concrete subject to tsunami actions was analyzed. The first part of the project involved an in-depth analysis of the state-of-the-art on the main international standards and guidelines for the modeling of tsunami actions on structures. The main empirical fragility curves obtained from post-event survey data were analyzed to deepen the structural response. The next phase involved finding data on coastal residential buildings in the areas covered by the project for the definition of typological classes of buildings. For each class, fragility curves have been obtained, for different damage states, based on structural analyses carried out on millions of mechanical models made in line with the typological characteristics of the classes of analyzed buildings. Finally, damage scenarios have been made in terms of the number of residential buildings involved, the costs of reconstruction and the population involved depending on data collected and the results obtained in the previous phases.
SPOT project 2
Duration of activities 2020-2022
The H&RA Lacinia project, a continuation of the SPOT project, aims to achieve damage scenarios in a detailed area, reduced comparing to the previous study. In addition, tsunami vulnerability analysis will be extended to other structural types such as infrastructure, strategic buildings and industrial buildings.
