Economic losses resulting from extreme weather events such as storms, hurricanes, and high-speed wind gusts result in significant annual costs for several countries, including Italy.

In this context, structural fragility assessment plays a key role in risk management, especially for industrial buildings, where the economic impact can be significant. This thesis therefore aims to assess the structural fragility of industrial building roofs commonly found in Italy.

Perdite economiche derivanti da eventi atmosferici estremi come tempeste, uragani e raffiche di vento ad alta velocità comportano costi annuali molto elevati per diversi paesi, tra cui l’Italia. Talvolta infatti, le strutture attuali non riescono a garantire un sufficiente margine di sicurezza in uno scenario di cambiamento climatico. In questo contesto, la stima della fragilità strutturale ha un ruolo chiave per la gestione del rischio, soprattutto nel caso di edifici industriali per cui l’impatto economico può essere significativo. Questa tesi vuole quindi valutare la fragilità strutturale delle coperture di edifici industriali comunemente presenti in Italia. Le analisi verranno estesa a diverse configurazioni strutturali in modo tale da valutare le variabili maggiormente significative. I risultati vengono forniti in abachi riassuntivi utili per una valutazione della fragilità strutturale per un ampio range di geometrie di fabbricati. Infine verranno fornite delle stime preliminari di rischio legato adeventi atmosferici estremi.

Abstract
Economic losses resulting from extreme weather events such as storms, hurricanes, and high-speed wind gusts result in significant annual costs for several countries, including Italy. Indeed, current structures sometimes fail to provide a sufficient safety margin in a climate-change scenario. In this context, structural fragility assessment plays a key role in risk management, especially for industrial buildings, where the economic impact can be significant. This thesis therefore aims to assess the structural fragility of industrial building roofs commonly found in Italy. The analyses will be extended to various structural configurations to assess the most significant variables. The results are presented in summary tables useful for assessing structural fragility for a wide range of building geometries. Finally, preliminary risk estimates related to extreme weather events will be provided.| File | Dimensione | Formato | |
