Seismic fragility analysis using stochastic polynomial chaos expansions [PDF]
Probabilistic Engineering Mechanics, 2023 Within the performance-based earthquake engineering (PBEE) framework, the fragility model plays a pivotal role. Such a model represents the probability that the engineering demand parameter (EDP) exceeds a certain safety threshold given a set of selected intensity measures (IMs) that characterize the earthquake load.

Seismic fragility analysis of coupled building‐slope systems
Earthquake Engineering & Structural Dynamics, 2023 AbstractBuildings located on hill slopes are subjected to additional effects under seismic action compared with those on flat ground. This article presents Incremental Dynamic Analyses of coupled building‐slope systems incorporating topographic amplification, nonlinear slope movement and irregular structural configuration of hill‐side buildings.

Seismic Fragility Analysis of Structures Based on Adaptive Gaussian Process Regression Metamodel
Shock and Vibration, 2021 Metamodel-based seismic fragility analysis methods can overcome the challenge of high computational costs of problems considering the uncertainties of earthquakes and structural parameters; however, the accuracy of metamodels is difficult to control.

Energy-based procedures for seismic fragility analysis of mainshock-damaged buildings
Frontiers in Built Environment, 2023 In recent decades, significant research efforts have been devoted to developing fragility and vulnerability models for mainshock-damaged buildings, i.e., depending on the attained damage state after a mainshock ground motion (state-dependent fragility ...

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