Statistical Analysis of Fragility Curves [PDF]
Journal of Engineering Mechanics, 2000 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 ...

Are seismic fragility curves fragile?
Probabilistic Engineering Mechanics, 2021 Abstract A hypothetical seismic site is constructed for which the probability law of the seismic ground acceleration process X ( t ) is specified. Since the seismic hazard is known, the performance of the incremental dynamic analysis- (IDA) and multiple stripe analysis- (MSA) based fragilities, which are used extensively in Earthquake ...

Bridge-specific fragility analysis: when is it really necessary? [PDF]
, 2018 In seismic assessment of bridges the research focus has recently shifted on the derivation of bridge-specific fragility curves that account for the effect of different geometry, structural system, component and soil properties, on the seismic behaviour ...

Guidelines for deriving seismic fragility functions of elements at risk: Buildings, lifelines, transportation networks and critical facilities [PDF]
, 2013 The objective of SYNER-G in regards to the fragility functions is to propose the most appropriate functions for the construction typologies in Europe. To this end, fragility curves from literature were collected, reviewed and, where possible, validated ...

Seismic vulnerability maps of Timisoara historical center based on fragility curves [PDF]
, 2016 The seismic vulnerability assessment on a territorial scale requires the application of simplified procedures. Data collection is usually carried out by adopting external inspections; for this reason the knowledge gained for the considered buildings is ...

A proposed methodology for deriving tsunami fragility functions for buildings using optimum intensity measures [PDF]
, 2016 Tsunami fragility curves are statistical models which form a key component of tsunami risk models, as they provide a probabilistic link between a tsunami intensity measure (TIM) and building damage. Existing studies apply different TIMs (e.g.

Bayesian tsunami fragility modeling considering input data uncertainty [PDF]
, 2016 Empirical tsunami fragility curves are developed based on a Bayesian framework by accounting for uncertainty of input tsunami hazard data in a systematic and comprehensive manner. Three fragility modeling approaches, i.e.
