Physical Vulnerability. Disaster vulnerability and resiliency theorists recognize that every community has varying degrees of disaster vulnerability and the potential to recover resiliently (Queiro-Tajalli & Campbell, 2002). In addition, the results obtained for the target area cannot be extended to other towns and cities. Negligible to slight damage (no structural damage, slight non-structural damage): Hair-line cracks in very few walls. The transformation of the physical damage into economic loss can be conducted through the following total probability relationship: where n is the number of damage states considered, P(dsi | IM) is the probability of a building sustaining damage state dsi given the intensity measure IM; E(C>c|dsi) is the complementary cumulative distribution of the cost (loss) given dsi; E(C>c|im is the complementary cumulative distribution of cost (or loss) given a level of intensity IM. Principal steps of the capacity spectrum-based procedures for the calculation of seismic performance (modified from Lang, 2013). Overall, the building classification should cover all types of conventional buildings that are available and that are representative for the target area. Building damage distribution and the conversion in terms of economic loss for Guwahati city, for the 1897 Shillong earthquake scenario, India. Figure 11. Figure 12. Extensive spalling in columns (possible shortening) and beams; severe joint damage; some reinforcing buckled. DISASTER VULNERABILITY, RISK . Existing approaches for physical damage-to-ground motion intensity correlations. Physical Vulnerability: Meaning the potential for physical impact on the physical environment – which can be expressed as elements-at-risk (EaR). A building’s physical vulnerability to earthquakes describes its susceptibility to damage that can be caused by a given ground-motion Intensity Measure (IM). Table 6 illustrates an example of a DPM-based physical vulnerability model. Globally, the negative influence of natural disasters is steadily increasing over the past decades in terms of the rising number of people affected and the growing proportion of … The uncertainty in the demand is introduced by the record-to-record variability, which captures the variability in the complexity of the mechanism of the seismic source, path attenuation, and site effects of the seismic event. Hence, it represents the mean damage an individual building of this typology will experience. Several definitions of collapse failure have been proposed. a range of social, economic, physical, and political vul-nerabilities. Empirical methods that generate physical damage-to-ground motion intensity relationships incorporate assumptions and approaches that are based on field observations and statistical analysis of building damage data (i.e., the seismic performance of the building) from past earthquake events. Second, without a sustained focus on children, their special needs may be neglected. Extensive damage to beams; spalling of cover and shear cracking (<1/8″ width) for ductile columns; minor spalling in non-ductile columns; joint cracks < 1/8″ wide. However, reducing or better quantifying the uncertainty associated with one of the parameters when computing physical vulnerability does not necessarily mean improving the overall reliability and robustness of the results. the uncertainty associated with the damage state threshold. These methods are differentiated through the approaches and assumptions implemented for the correlation of physical damage with a ground-motion intensity measure. To identify structural or physical vulnerability to climate change, it is useful to refer to the three usual components of economic vulnerability (size of the shocks, exposure to the shocks, resilience), and to consider that structural vulnerability is mainly captured through the shock and exposure components, while resilience is more related to policy or to other variables best considered separately … In the fields of earthquake engineering and seismic risk reduction the term “physical vulnerability” defines the component that translates the relationship between seismic shaking intensity, dynamic structural uake damage and loss assessment discipline in the early 1980s, which aimed at predicting the consequences of earthquake shaking for an individual building or a portfolio of buildings. variety of disaster risks. Manhood is personified in those who leave behind safety. The selected scenario is a M 7.5 earthquake located at 40 km distance to the city center. In many cases some of the methodologies have been implemented using simplified assumptions in order to reduce data gathering and calculation efforts for many different reasons. Disaster research often strives to show that these risks affect morbidity, mortality or well- being in some way. Moreover, the extensive seismic risk assessment and modeling studies that have been implemented in many different parts of the world, covering a wide range of building typologies and portfolios, have resulted in a wealth of seismic vulnerability models available in literature that can be used for future applications, such as fragility functions for North American building typology classes provided in HAZUS-MH (FEMA-NIBS, 2003), the European vulnerability database developed under SYNER-G (2011a, 2011b), or the worldwide vulnerability database compiled within the Global Earthquake Model (GEM) framework (Rossetto, Ioannou, Grant, & Maqsood, 2014; D’Ayala, & Meslem, 2013). People with physical disabilities are highly vulnerable during natural disasters. There are many different factors that determine vulnerability. Figure 10. ASCE/SEI 41-06 (ASCE 2007); ATC-58-2 (ATC 2003), FEMA-356 (ASCE 2000), Minor hairline cracking; limited yielding possible at a few locations; no crushing (strains below 0.003). The UNISDR defines vulnerability as “the conditions determined by physical, social, economic and environmental factors or processes, which increase the susceptibility of a community to the impact of hazards” (UNISDR 2009).Vulnerability may vary within a population by subgroup (e.g. Many research programs have produced a compendium of empirical Damage Factor values (including material and labor costs), given a certain damage threshold, and which can be used as default values in cases when economic data (i.e., building repair or reconstruction costs for a given damage state ds) are not available (D’Ayala, Meslem, Vamvatsikos, Porter, & Rossetto, 2015). The authors acknowledge financial support from the Royal Norwegian Ministry of Foreign Affairs. The normal cumulative distribution function and the logistic distribution function have been used in cases where the intensity measure can take negative values. Other models that use different parameters can also be found in literature: relating element to yielding and ultimate rotation/displacement limits (e.g., FEMA, 1997; CEN, 2004, 2005; Dolsek & Fajfar, 2004), or relating roof displacement to yielding and ultimate limits, i.e., on a global level (e.g., FEMA, 1997; Giovinazzi, 2005; Barbat, Moya, & Canas, 1996; Kappos, Panagopoulos, Panagiotopoulos, & Penelis, 2006; Lagomarsino & Giovinazzi, 2006). For instance, HAZUS-MH (FEMA-NIBS, 2003) has provided default values for the Damage Factor, which include material and labor costs related to 33 occupancy classifications in the United States. The process of using these physical vulnerability models in order to generate physical damage distribution and the conversion in terms of monetary losses accrued as the result of the damage, is illustrated in Figure 9. This uncertainty is taken into account by the majority of the studies reviewed either by selecting a certain number of ground motion records and/or by scaling the records. Extensive damage to beams; spalling of cover and shear cracking (<1/8″) for ductile columns; minor spalling in non-ductile columns; joints cracked < 1/8″ width. Fifty-seven articles were identified in the primary search, with seven studies selected for review. Partial or total failure/cracking of columns and beams. urban risk and physical vulnerability – by formulating the progression of vulnerability proposed in the Pressure and Release Model (PAR) as a multi-scalar phenomenon. This paper provides a review of the current body of knowledge on the lived experiences of adults with a physical disability in natural disasters. The influence of physical vulnerability models has been investigated by comparing risk results obtained using customized physical vulnerability models with those obtained using a set of physical vulnerability models (i.e., fragility curves) provided by HAZUS-MH (FEMA-NIBS, 2003). Large plaster or gypsum-board cracks at corners of door and window openings; small diagonal cracks across shear wall panels exhibited by small cracks in stucco and gypsum wall panels; large cracks in brick chimneys; toppling of tall masonry chimneys. Within the RISK-UE framework, a research project consortium financed by the European Commission, a procedure was introduced which allowed the generation of DPMs considering the EMS-98 building vulnerability classes (Milutinovic & Trendafiloski, 2003). Inzamul Haque Sazal. Vulnerability may also vary in its forms: poverty, for example, may mean that housing is unable to withstand an earthquake or a hurricane, or lack of preparedness may result in a slower response to a disaster, leading to greater loss of life or prolonged suffering. In addition, macroseismic intensity is a non-instrumental parameter primarily based on damage observations and subjective opinions (feelings, impressions, sensations) of individuals.
