A multi-dimensional definition of fragility is developed considering multiple variables such as floor acceleration and interstory drifts. The limit states which have uncertainties are defined as random variables in the calculation of fragility. A random description of the limit state has been adopted to calculate fragility and different cases have been considered. A case study of a Hospital loc...

In the literature there is no clear evidence of a relationship between thyropathies and fragility fractures. The aim of our study is to define the prevalence of thyroid disease in a study sample made up of subjects with fragility fractures and from the same geographical area. We retrospectively studied the "hospital discharge records" (HDR) in the Apulian Database for the period 2008-2013 in or...

This paper presents the formulation of a time-dependent seismic fragility format for bridges, as well as new insights into the potential effects of aging and deterioration on seismic vulnerability traditionally neglected in fragility modeling, including joint impacts of multiple component deterioration not investigated to date. The study evaluates the impact of lifetime exposure to chlorides fr...

This paper presents a statistical analysis of structural fragility curves. Both empirical and analytical fragility curves are considered. The empirical fragility curves are developed utilizing bridge damage data obtained from the 1995 Hyogo-ken Nanbu (Kobe) earthquake. The analytical fragility curves are constructed on the basis of the nonlinear dynamic analysis. Two-parameter lognormal distrib...

Bridges are essential lifelines for transportation networks during and after an earthquake event, providing routes for emergency response and evacuations. For this reason, bridge fragility modeling has been a major focus in earthquake research, as fragility analysis aids in the post-event determination of possible damage of bridges as well as in pre-event mitigation planning. While fragility an...

Fragility curves for retrofitted bridges indicate the influence of various retrofit measures on the probability of achieving specified levels of damage. This paper presents an analytical methodology for developing fragility curves for classes of retrofitted bridge systems. The approach captures the impact of retrofit on the vulnerability of multiple components, which to date has not been adequa...

The aim of this study was to assess the usefulness of the inbred rat model for studies of genetic influences on skeletal fragility. We characterized bone mass, geometry, and skeletal biomechanics in 11 inbred strains of rats. This study showed that considerable variation exists in bone structure, areal bone mineral density (aBMD), and fragility phenotypes among inbred strains of rats. Interesti...

We examine the sensitivity and surface bias of convolved DGLV radiative and elastic loss in a realistic geometry including Bjorken expansion. We find that this more faithful treatment of the medium density is not a priori reproducible via fixed length approximations, and neither the fragility nor the surface emission of BDMPS-based models is seen.

cartilage hair hypoplasia (chh), is a rare cause of metaphyseal chondrodysplasia and short stature. other features included hair abnormality, immunodeficiency, anemia, gastrointestinal disorders (hirschsprung disease, celiac, …) and increased risk of cancer. the disease is an autosomal recessive disorder and previously has not been reported in iran. we report a 9-year-old boy diagnosed as carti...
