Seismic fragility analysis of two-story and three-span metro station structures based on IDA method
Yantu gongcheng xuebao, 2020 Based on the non-linear soil-structure interaction model for a two-storey and three-span metro station in a typical underground engineering site, an IDA (incremental dynamic analysis)-based structural seismic fragility analysis method is introduced for ...

Developments 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 System Based on Fuzzy Failure Criteria
Advances in Civil Engineering, 2019 In the traditional bridge seismic fragility analysis, the criterion for judging the structural damage state is clear. That is to say, when the damage index exceeds a specific value, the structure is judged to enter the new damage state.

Adaptive artificial neural networks for seismic fragility analysis [PDF]
2017 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 ...

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.

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.
