Description du projet
Protection sismique des structures du patrimoine
La sauvegarde du patrimoine culturel bâti pour les générations futures constitue une préoccupation sociétale majeure. L’effondrement hors plan des murs en maçonnerie désigne le mécanisme de dommage sismique le plus fréquemment observé dans ces bâtiments. Le projet STAND4HERITAGE, financé par l’UE, élaborera des approches de prédiction de la réponse sismique des structures en maçonnerie. Conformément à l’agenda 2030 des Nations unies pour des villes et des communautés durables, il intégrera les étapes nécessaires à l’évaluation hors plan et développera des modèles stochastiques pour prendre en compte le signal sismique dans la réponse et la capacité dynamiques. Le projet s’appuiera sur l’expérience du chercheur principal dans ce domaine et sur l’expertise interdisciplinaire de son équipe pour relever le défi de fournir des solutions d’intervention optimales pour les bâtiments du patrimoine.
Objectif
STAND4HERITAGE ambitiously engages in introducing new standards for safeguarding built cultural heritage for the next generations, which is a major societal demand. Due to its large diversity, the accurate description of the structural behaviour of heritage buildings is still an open issue, particularly when subjected to earthquake ground motions. Among the most frequently observed seismic damage mechanisms in these buildings, the out-of-plane of masonry walls is acknowledged as the main cause for building loss and injuries to people. There are many unresolved challenges to effectively assess the out-of-plane seismic behaviour of masonry structures. First, it is necessary to understand less known phenomena in masonry dynamics, which largely influence the out-of-plane behaviour and capacity of heritage buildings. A recent blind exercise to predict the capacity of a benchmark masonry structure to resist a dynamic excitation demonstrated that, although advanced simulation tools are available, leading international researchers are still unable to consistently provide a collapse estimate. STAND4HERITAGE will address the aspects for successful development of approaches for seismic response prediction of masonry structures, integrating the necessary stages for out-of-plane assessment. It will generate novel: integrated stochastic-based models to consider the seismic signal in the dynamic response and capacity; datasets of the dynamic response evaluated after an extensive shake table testing program; numerical approaches for simulation of the out-of-plane seismic behaviour; an integrated analytical approach for out-of-plane seismic assessment of heritage buildings. STAND4HERITAGE objectives are in line with the UN 2030 agenda for sustainable cities and communities. The project will be founded on the experience of the PI in the topic, and on the interdisciplinary expertise of his team in facing the challenges to provide optimal intervention solutions for heritage buildings.
