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 ...

Use of Generalized Lambda Models For Seismic Fragility Analysis
8th 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

Seismic Fragility Analysis of Bridge Pier
IOP 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-

A method of seismic performance evaluation based seismic fragility analysis [PDF]
MATEC Web of Conferences, 2018 For evaluating seismic performance of structures, a method is presented based on increment dynamic analysis and seismic fragility analysis. Firstly, the failure probability equation is deduced, in which the relationships of seismic intensities and response demands can be determined by the increment dynamic analysis. On this basis the probabilities with
