Riassunto
L’indagine sul Palazzo è partita dallo studio delle fonti storiche, attraverso le quali sono state messe in luce le fasi, le vicende e gli interventi subiti dal manufatto. Il rilievo geometrico e indagini di tipo visivo hanno permesso di individuare le criticità più evidenti, principalmente legate allo stato fessurativo, alla presenza di muri in falso di notevole spessore e allo stato della copertura. Per quest’ultima, dotata di elementi sottodimensionati e degradati, viene proposto un progetto di rifacimento con nuovi elementi in legno. Il Palazzo, grazie al software Aedes PCM, è stato modellato in 3D, schematizzato seguendo la teoria del telaio equivalente e studiato attraverso analisi statica non lineare. Le scarse informazioni circa i materiali costituenti l’edificio, hanno reso necessaria un’analisi parametrica, svolta assegnando varie tipologie di materiale, con caratteristiche meccaniche differenti, agli elementi costituenti il telaio e studiando per ognuna la risposta sismica del manufatto. Il comportamento sismico dell'edificio è stato anche indagato localmente, attraverso lo studio dei meccanismi locali che potrebbero formarsi durante un terremoto. La tesi mette in luce la necessità di studi più accurati sul manufatto e sugli elementi che lo costituiscono, nell'ottica della conservazione attraverso interventi mirati e poco invasivi.
The investigation of the building started from the study of historical sources, through which the phases, events and interventions undergone by the building were brought to light. The geometric survey and visual investigations made it possible to identify the most evident criticalities, mainly related to the cracking state, the presence of very thick false walls and the state of the roof. For the latter, equipped with undersized and degraded elements, a refurbishment project with new wooden elements is proposed. The building, thanks to the Aedes PCM software, was modeled in 3D, schematized following the theory of the equivalent frame and studied through non-linear static analysis. The scarce information about the building materials made it necessary to carry out a parametric analysis, carried out by assigning various types of material, with different mechanical characteristics, to the elements making up the frame and studying the seismic response of the building for each one. The seismic behavior of the building was also investigated locally, through the study of the local mechanisms that could form during an earthquake. The thesis highlights the need for more accurate studies on the artefact and on the elements that constitute it, with a view to conservation through targeted and minimally invasive interventions.
