“…However, similar studies to those listed above have been performed for other cities throughout the world, including Lisbon, Portugal (D'Ayala et al, 1997;Ramos and Lourenco, 2004), Basel, Switzerland (Fah et al, 2001), Istanbul, Turkey (Erdik et al, 2003), Potenza, Italy (Dolce et al, 2006), San Francisco, USA (Kircher et al, 2006) and many others of various size and scope.…”

“…The only theory proposed to explain the increased displacements is foundation compliance, although it is admittedly noted that this would not account for the level of discrepancy observed. It was also noted in Dolce et al (2006) that although ultimate strengths were within +/-30% of the average values seen in literature, that it is necessary to take into account the very large ultimate displacements of URM buildings adopted by HAZUS, which the author attributes to the practice of defining damage states that correspond to partial collapse of buildings. Penelis (2006) also concludes that the capacity curves provided by HAZUS for URM buildings allow extremely high values (1.8%) for ultimate drift, which can only be justified for reinforced masonry buildings.…”

Simulation-Based Fragility Relationships for Unreinforced Masonry Buildings

Unreinforced masonry (URM) structures represent a significant portion of the residential building stock of the Central and Eastern United States (CEUSA), accounting for 15% of homes in the 8-state region impacted by the New-Madrid Seismic Zone and an even greater portion of the building stock in most other regions of the world. In addition to significant population, the brittle nature of URM buildings further supports a thorough consideration of seismic response given the susceptibility to severe failure modes. Currently, there is a pressing need for analytically based fragility curves for URM buildings. In order to improve the estimation of damage state probabilities through the development of simulation-based masonry fragilities, an extensive literature survey is conducted on pushover analysis of URM structures. Using this data, capacity diagrams are generated, from which damage exceedance limit states are defined.Demand is simulated using synthetically derived accelerograms representative of the CEUSA.Structural response is evaluated using an advanced capacity spectrum method developed at the Mid-America Earthquake Center. Capacity, demand, and response are thus derived analytically and response data is used to generate an improved and uniform set of fragility curves for use in loss-assessment software via a framework amenable to rapid expansion of pushover database and variation of ground motion records. A set of best practices is hereby developed for selection and use of experimental and analytical data, input ground motions, analysis of structural capacity, limit state definitions, seismic design categories, and probabilistic analysis methods. Curves are expressed in multiple forms for wide range of use in loss-assessment applications. Results are discussed and compared with other relationships developed in the literature, along with those generated using HAZUS opinion-based capacity data. The parameters of the improved fragility relationships developed and presented in this thesis are provided and suggested for reliable use in seismic loss assessment software.iii To my wife, Erin iv ACKNOWLEDGMENTS

“…Generally, a seismic economic losses model could be referred to different kind of losses (direct and indirect). The direct losses are the repair costs necessary to restore the buildings preearthquake state [1].…”

“…This issue plays a fundamental role in seismic risk mitigation strategies and it should be strongly considered in all planning activities. The available studies are generally based on buildings stock and the possible seismic occurrence of earthquakes [1], [2], [3]. The main problem is the strong disproportion between the available public economic resources and the buildings that require retrofitting interventions.…”

“…they have an unsatisfactory seismic capacity. In the last decades, many procedures have been developed to check the seismic vulnerability of urban areas [5,6,7,8,9], which can be divided into three main groups: the empiric, the analytical and the hybrid methods. The vulnerability analyses are focused on the reliability of the buildings with regard to the seismic actions expectable for the area.…”
