Embankment seismic fragility assessment: A case study on Xi'an-Baoji expressway (China). [PDF]
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 fragility analysis using stochastic polynomial chaos expansions [PDF]
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

Quasi-static testing of UHPC cupped socket piers-footing connection and its seismic fragility analysis under near-fault ground motions [PDF]
Assembly construction is extensively employed in bridge construction due to its ability to accelerate construction and improve quality. To speed the recovery of bridges after major earthquakes, this study proposes an assembled connection for precast ...

Vertical Seismic Effect on the Seismic Fragility of Large-Space Underground Structures
The measured vertical peak ground acceleration was larger than the horizontal peak ground acceleration. It is essential to consider the vertical seismic effect in seismic fragility evaluation of large-space underground structures.

Are seismic fragility curves fragile?
Abstract A hypothetical seismic site is constructed for which the probability law of the seismic ground acceleration process X ( t ) is specified. Since the seismic hazard is known, the performance of the incremental dynamic analysis- (IDA) and multiple stripe analysis- (MSA) based fragilities, which are used extensively in Earthquake ...

Impact of asymmetrical corrosion of piers on seismic fragility of ageing irregular concrete bridges
This article investigates the seismic fragility of ageing irregular multi-span reinforced concrete (RC) bridges. Different irregularity sources are considered, including: (i) substructure stiffness irregularity arising from the unequal-height piers, (ii)

Seismic Fragility Relationships for Structures [PDF]
AbstractStructural fragility assessment is a fundamental component of modern performance-based earthquake design and assessment processes. Major advances in fragility functions development and implementation have occurred over the past three decades.
