Description du projet
Des textiles innovants pour réhabiliter les bâtiments du patrimoine culturel
De récents tremblements de terre et catastrophes naturelles ont détérioré les performances structurelles de certains vieux bâtiments et édifices du patrimoine culturel (CHB pour Cultural Heritage Building) de l’UE. Par ailleurs, les CHB sont des bâtiments à forte consommation d’énergie. Par conséquent, la nécessité d’améliorer les bâtiments du patrimoine culturel existants et d’adopter des techniques innovantes en matière de résilience sismique, de modernisation énergétique et de surveillance de l’intégrité des structures (SHM pour Structural Health Monitoring) devient de plus en plus criante. Le rôle de la SHM est essentiel pour l’évaluation constante de l’état structurel des bâtiments et la formulation de propositions de maintenance rentables. Le projet STRETCH, financé par l’UE, développera des techniques innovantes basées sur des matériaux multifonctionnels intelligents afin d’augmenter la résilience des CHB et de réduire la consommation d’énergie. Le projet étudiera une nouvelle méthode qui intègre le renforcement via des textiles techniques avec une isolation thermique et des capteurs de contraintes, assurant à la fois la rénovation structurelle et énergétique et la SHM.
Objectif
This project aims to develop novel techniques using smart multifunctional materials for the combined seismic-plus-energy retrofitting, and Structural Health Monitoring (SHM) of the European cultural heritage buildings (CHB). The need for upgrading the existing old and CHB is becoming increasingly important for the EU countries, due to: (1) their poor structural performance during recent earthquakes (e.g. Italy, Greece) or other natural hazards (e.g. extreme weather conditions) that have resulted in significant economic losses, and loss of human lives; and (2) their low energy performance which increases significantly their energy consumption (buildings are responsible for 40% of EU energy consumption). Moreover, the SHM of the existing buildings is crucial for assessing continuously their structural integrity and thus to provide information for planning cost effective and sustainable maintenance decisions. Since replacing the old buildings with new is not financially feasible, and even it is not allowed for CHB, their lifetime extension requires considering simultaneously both structural and energy retrofitting. It is noted that the annual cost of repair and maintenance of existing European building stock is estimated to be about 50% of the total construction budget, currently standing at more than €300 billion. To achieve cost effectiveness, STRETCH explores a novel approach, which integrates technical textile reinforcement with thermal insulation systems and strain sensors to provide simultaneous structural-plus-energy retrofitting combined with SHM, tailored for masonry cultural heritage building envelopes. The effectiveness of the proposed retrofitting system will be validated experimentally and analytically. Moreover, draft guidelines and recommendations for determining future research on the use of smart composite materials for the concurrent retrofitting (structural-plus-energy) and SHM of the existing cultural heritage buildings envelopes will be proposed.
