Exploring cost-benefit analysis for earthquake risk reduction
| Resumo: | Masonry buildings comprise more than 50% of the masonry building stock in Portugal according to the 2011 national census. This construction typology has revealed a poor performance during the destructive events which took place in Portugal in the last century. Past efforts to characterize the seismic vulnerability of this type of construction have focused mostly on individual buildings. In this dissertation, cost-benefit analyses are performed for a set of retrofitting techniques compatible with masonry buildings. Chapter 1 presents the aims, motivations and scope of the research, hence explaining the context of the current research. In Chapter 2, a literature review is presented with the purpose to introduce the reader to topics associated to this research. Important topics are addressed as building stock characterisation, physical damage and fatality assessment, retrofitting and cost-benefit analysis. Chapter 3 is devoted to the geometric and mechanical characterization of the two most common stone masonry building typologies in Portugal, limestone and granite. A statistical treatment is made, and probability density functions are defined for important structural features. Chapter 4 aims at implementing advanced numerical models and developing damage fragility functions for masonry buildings. Chapter 5 discusses the state-of-the-practice in fatality assessment and introduces the outcomes of the advanced structural analysis to propose a new fatality assessment framework. In Chapter 6, retrofitting techniques compatible with masonry buildings in Portugal are modelled and numerically assessed, to develop fragility and fatality vulnerability functions. Chapter 7 comprises the implementation of consequence functions at the national scale. Finally, the main outcomes, principal conclusions and future research is discussed in Chapter 8. |
