La ragione di questo studio è quella di sviluppare un approccio metodologico per ottenere misure efficaci di mitigazione strutturale per edifici residenziali vulnerabili da inondazioni, mediante valutazione dei danni post-evento. Informazioni relative ai danni post-disastro possono essere raccolte utilizzando metodi diversi per gli edifici danneggati, per meglio comprendere la necessità di un intervento. Le componenti strutturali colpite dall’inondazione sono poi analizzate e le perdite sono valutate. Dopo aver analizzato i danni sostenuti, sono considerate le possibili misure strutturali per mitigare nel miglior modo possibile il rischio futuro. Una valutazione economica deve essere svolta per le possibili misure, usando lo strumento dell’analisi costi-benefici, che permette di comprendere l’efficacia dei costi delle misure di mitigazione strutturale. L'approccio metodologico sviluppato per identificare le misure di mitigazione strutturale efficaci utilizzando valutazione post-danno è poi applicato ad un caso di studio reale relativo ad un evento alluvionale passato. L'evento ha avuto luogo in Italia nel mese di novembre 2012, nella regione Umbria. Molti edifici sono stati gravemente colpiti dal disastro, che ha distrutto edifici storici culturali, residenziali e commerciali. Tra i numerosi edifici che sono stati gravemente colpiti, 52 edifici residenziali sono presi come campione e sono valutati utilizzando i dati sui danni, raccolti tramite indagini post-evento. L'obiettivo principale di questa tesi è quello di sviluppare una metodologia per valutare lo scenario delle inondazioni passate attraverso una valutazione post-danni in modo da valutare l'efficacia delle misure di mitigazione per gli edifici residenziali utilizzando lo strumento dell’analisi costi-benefici. L’applicazione della metodologia sviluppata ad un caso di studio reale italiano ha permesso di verificarne la applicabilità sulla base dei risultati ottenuti. Questa valutazione economica, che utilizza lo strumento dell’analisi costi-benefici, permetterà ai decision makers di scegliere le migliori misure di mitigazione strutturale in base all’efficacia dei costi, in modo da affrontare i futuri eventi di inondazione.

Abstract
The reason behind this study is to develop a methodological approach to obtain effective structural mitigation measures to residential buildings vulnerable to flood disaster, using post event damage assessment. Post disaster damage information can be collected using different methods for buildings which has undergone damage, to better understand the need of intervention. Structural components which are affected due to the flood are analyzed and damage losses are evaluated. After analyzing the damages incurred, possible structural measures are considered to mitigate future risk in a best possible way. An economical evaluation needs to be carried out for the possible measures using cost benefit analysis tool, which helps to understand the cost effectiveness of structural mitigation measures. The developed methodological approach in identifying the effective structural mitigation measures using post event damage assessment is applied to a real case study for a past flood event. The event took place during November 2012, in the region of Umbria, Italy. Major number of buildings were severely affected by the disaster, bringing down the cultural, residential and commercial buildings. Among huge number of buildings which were severely affected, 52 (fifty-two) number of sample residential buildings were evaluated using damage data collected by post event survey. Main goal of this thesis study is to develop a methodology for assessing the past flood scenario by post event damage assessment to evaluate effectiveness of mitigation measures for residential buildings using cost benefit analysis tool. Applying the developed methodology to a real case study in Italy, allowed to verify the viability of developed methodology based on results. Economical evaluation using cost benefit analysis tool will allow decision makers to choose suitable cost effective structural mitigation measures for residential buildings to face the future flood event.| File | Dimensione | Formato | |
