Descripción del proyecto
Protección sísmica de estructuras patrimoniales
Salvaguardar el patrimonio cultural construido para la siguiente generación es una de las principales demandas sociales. El colapso fuera del plano de las paredes de mampostería es el mecanismo de daño sísmico observado con mayor frecuencia en estos edificios. El proyecto STAND4HERITAGE, financiado con fondos europeos, desarrollará métodos para la predicción de la respuesta sísmica de las estructuras de mampostería. En consonancia con la Agenda 2030 para las ciudades y comunidades sostenibles, integrará las etapas necesarias para la evaluación fuera del plano y desarrollará modelos basados en la estocástica a fin de tener en cuenta la señal sísmica en la capacidad y respuesta dinámica. El proyecto se basará en la experiencia del investigador principal en el tema, y en los conocimientos interdisciplinarios de su equipo para afrontar los retos de proporcionar soluciones de intervención óptimas para los edificios patrimoniales.
Objetivo
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.
