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

Quasi-static testing of UHPC cupped socket piers-footing connection and its seismic fragility analysis under near-fault ground motions [PDF]
Scientific ReportsAssembly 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
Advances in Civil Engineering, 2019 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?
Probabilistic Engineering Mechanics, 2021 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 ...

Seismic Vulnerability Assessment of Corruagted Steel Shear Walls Using Fragility Curves [PDF]
Journal of Structural and Construction Engineering, 2019 Structural damages and subsequently considerable economic losses that ever made in catastrophic seismic events caused reaserchers and codes gradually move from prescriptive design to performance-based design.
