Embankment seismic fragility assessment: A case study on Xi'an-Baoji expressway (China).

open access: yesPLoS ONE, 2021
Although embankment seismic damages are very complex, there has been little seismic fragility research yet. Researches on seismic fragility of bridges, dams and reinforced concrete (RC) structures have achieved fruitful results, which can provide ...

Seismic performance assessment of subway station structures considering fuzzy probability of damage states

open access: yesYantu gongcheng xuebao, 2022
Quantification of structural damage states in the fragility analysis and seismic performance evaluation of underground structures usually adopts the deterministic threshold values, which is a limitation in the framework of performance-based seismic ...

Adaptive artificial neural networks for seismic fragility analysis [PDF]

open access: yes2017 2nd International Conference on System Reliability and Safety (ICSRS), 2017
In seismic probabilistic risk assessment, fragility curves are used to estimate the probability of failure of a structure or its critical components at given values of seismic intensity measures, e.g. the peak ground acceleration. However, the computation of the fragility curves requires a large number of time-consuming mechanical simulations with the ...

Use of Generalized Lambda Models For Seismic Fragility Analysis

open access: yes8th International Symposium on Reliability Engineering and Risk Management, 2022
Seismic structural performances are typically characterized by fragility models. A fragility model provides the probability of exceeding a certain level of damage in the structure given a set of intensity measures (IMs) of the seismic excitations. The damage level is defined as a function of a given Engineering Demand Parameter (EDP) (e.g., the maximal

Dynamic Damage Mechanism and Seismic Fragility Analysis of an Aqueduct Structure

open access: yesApplied Sciences, 2021
The Concrete Damaged Plasticity (CDP) constitutive is introduced to study the dynamic failure mechanism and the law of damage development to the aqueduct structure during the seismic duration using a large-scale aqueduct structure from the South-to-North

A simplified approach to evaluate cyclic response and seismic fragility of corrosion damaged RC bridge piers

open access: yesDevelopments in the Built Environment, 2022
Safety of the existing corrosion damaged reinforced concrete (RC) bridges during a seismic event is a matter of increasing concern. To reduce the enormous economic loss and casualties, it is important to examine the potential seismic risk of corroded RC ...

Seismic Fragility Analysis of Bridge Pier

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract Bridges are classified as lifeline structures as they need to be functional in an earthquake event. The performance-based analysis of the existing bridges is important for the stakeholders. Information on seismic performance in terms of fragility of existing bridges in the country can provide valuable information to the decision-
