Methodology for the development of bridge‐specific fragility curves [PDF]
Earthquake Engineering & Structural Dynamics, 2016 SummaryA new methodology for the development of bridge‐specific fragility curves is proposed with a view to improving the reliability of loss assessment in road networks and prioritising retrofit of the bridge stock. The key features of the proposed methodology are the explicit definition of critical limit state thresholds for individual bridge ...

Fragility Curve Analysis of Medium Cable Stayed Bridge
Civil and Environmental Engineering, 2021 The seismic performance of a bridge can be shown by analyzing the vulnerability of the structure in resisting an earthquake motion and then developing into fragility curves. This study presents a convenient method to establish the fragility curve for the

Influences of site conditions and ground-motion frequency characteristics on structural fragility
Yantu gongcheng xuebao, 2023 Site conditions and ground-motion frequency characteristics play a significant role in structural response and seismic damage distribution. However, the current structure fragility analysis techniques have hardly considered such effects. Taking the ratio

An approach to derive seismic fragility curves [PDF]
IOP Conference Series: Materials Science and Engineering, 2021 Abstract Seismic risk assessment is needed for the evaluation of disaster management, emergency preparedness and prior retrofitting. Based on feasible collapse mechanisms and calculation of their associated seismic parameter Peak Ground Displacement, the failure analysis of the structure is identified.

A note on families of fragility curves—is the composite curve equivalent to the mean curve? [PDF]
Reliability Engineering & System Safety, 1994 Abstract This paper gives a rigorous proof of something that has been assumed intuitively by workers in seismic PRA; namely, that the ‘mean curve’ of a family of lognormal fragility curves is equal to the so-called ‘composite’ curve. This equality is shown to be equivalent to, and to result from, an obscure but interesting identity property of the ...

Development of fragility curves for railway embankment and ballast scour due to overtopping flood flow [PDF]
Natural Hazards and Earth System Sciences, 2016 Fragility curves evaluating a risk of railway embankment fill and track ballast scour were developed. To develop fragility curves, two well-documented events of single-track railway washout during floods in Japan were investigated.

Assessing the impact of ground-motion variability and uncertainty on empirical fragility curves [PDF]
, 2015 Empirical fragility curves, constructed from databases of thousands of building-damage observations, are commonly used for earthquake risk assessments, particularly in Europe and Japan, where building stocks are often difficult to model analytically (e.g.
