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 ...

Mainshock-Integrated Aftershock Vulnerability Assessment of Bridge Structures
Applied Sciences, 2020 Seismic fragility analysis is often conducted to quantify the vulnerability of civil structures under earthquake excitation. In recent years, besides mainshocks, strong aftershocks have been often witnessed to induce structural damage to engineered ...

SEISMIC FRAGILITY ANALYSIS OF STEEL STORAGE TANKS
Proceedings of the 5th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2015 Earthquakes can cause significant damages to industrial liquid storage tanks resulting in losses of functionality, fires or environmental contamination due to the leakage of hazardous chemicals. Typical damages of ground supported tanks during past earthquakes were in the form of cracking at the corner of the bottom plate and compression buckling of ...

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

Analysis of fragility levels of fragile five in terms of exchange rates
Pressacademia, 2017 This paper analyzes the structural breaks and times of “Fragile Five” currencies’ against USD Dollar. Thus study tries to find the consistency of “Fragile Five” via structural break unit root test over currencies. Paper analyzes the structural breaks under two parts which contain Jan 2010- June 2013 and July 2013-Dec 2016 by taking weekly closing ...

Influence of ground motion duration on seismic fragility of base isolated NPP structures
Journal of Materials and Engineering Structures, 2023 This study investigates the influence of earthquake duration on seismic fragility of base isolated nuclear power plant (NPP) structures. Two groups of ground motions are employed in performing time history analyses, in which short duration (SD) and long ...
