Descripción del proyecto
Tejidos innovadores para mejorar los edificios de patrimonio cultural
Los terremotos y las catástrofes naturales recientes han deteriorado el rendimiento estructural de los edificios antiguos y del patrimonio cultural de la Unión Europea. Al mismo tiempo, estos edificios presentan un elevado consumo energético. Por consiguiente, la necesidad de mejorar los edificios pertenecientes al patrimonio cultural y la adopción de técnicas innovadoras de resiliencia sísmica, rehabilitación energética y control de la salud estructural (SHM, por sus siglas en inglés) adquieren cada vez mayor importancia. El papel del SHM es fundamental para evaluar permanentemente del estado estructural de los edificios y generar propuestas de mantenimiento rentables. El proyecto STRETCH, financiado con fondos europeos, desarrollará técnicas innovadoras basadas en materiales multifuncionales inteligentes para aumentar la resiliencia de los edificios de patrimonio cultural y reducir su consumo energético. El proyecto estudia un nuevo método que integra un refuerzo textil técnico con aislamiento térmico y sensores de deformaciones, lo cual sirve tanto de rehabilitación estructural y de energía positiva como de SHM.
Objetivo
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.
