The present thesis aims to investigate the seismic behavior of reinforced masonry built with Autoclaved Aerated Concrete (AAC) blocks, evaluating its effectiveness as a technological solution for constructions in seismic zones. The core of the study consists of a critical analysis of the results obtained from an extensive experimental campaign conducted by the multinational company "Xella" on full-scale specimens. By studying the strength, displacement capacity, and failure mechanisms, the material's response under cyclic loading was characterized, comparing theoretical data with the actual experimental results. The work was further enriched by the analysis of specific case studies, which allowed for testing the validity of analytical models and validating the structure's performance in real-world application contexts. This system, which is already rapidly expanding in Northern Europe due to its excellent thermal and acoustic properties, emerges as a competitive and safe solution for the sustainable construction market in seismic areas.
Il seguente lavoro di tesi ha l'obiettivo di approfondire il comportamento sismico della muratura armata realizzata con blocchi in calcestruzzo aerato autoclavato (AAC), valutandone la sua efficacia come soluzione tecnologica per le costruzioni in zona sismica. Il nucleo centrale dello studio risiede nell’analisi critica dei risultati ottenuti da una vasta campagna sperimentale condotta dall’azienda “Xella” su campioni in scala reale. Attraverso lo studio della resistenza, della capacità di spostamento e dei meccanismi di danneggiamento, è stata caratterizzata la risposta del materiale sottoposto ad azioni cicliche, confrontando i dati teorici con i risultati sperimentali. Il lavoro è stato arricchito dall’analisi di specifici casi studio, che hanno permesso di testare la validità dei modelli analitici e di validare le prestazioni della struttura in contesti applicativi reali. Tale sistema, già in forte espansione nell’Europa settentrionale per le eccellenti proprietà termiche ed acustiche, si delinea così come una soluzione competitiva e sicura anche per il mercato dell’edilizia sostenibile in aree a rischio sismico.

Abstract
The present thesis aims to investigate the seismic behavior of reinforced masonry built with Autoclaved Aerated Concrete (AAC) blocks, evaluating its effectiveness as a technological solution for constructions in seismic zones. The core of the study consists of a critical analysis of the results obtained from an extensive experimental campaign conducted by the multinational company "Xella" on full-scale specimens. By studying the strength, displacement capacity, and failure mechanisms, the material's response under cyclic loading was characterized, comparing theoretical data with the actual experimental results. The work was further enriched by the analysis of specific case studies, which allowed for testing the validity of analytical models and validating the structure's performance in real-world application contexts. This system, which is already rapidly expanding in Northern Europe due to its excellent thermal and acoustic properties, emerges as a competitive and safe solution for the sustainable construction market in seismic areas.| File | Dimensione | Formato | |
