A Multi Record Based Artificial Near Fault Ground Motion Generation Method
MethodsX, 2020 Near fault ground motion is a kind of ground motion with great damage, which is difficult to simulate. The amplitude and frequency functions of near fault ground motion vary greatly with time.

Reconstruction and validation of ground motions across dip-slip faults: an application to response analysis of a long-span suspension bridge [PDF]
Scientific ReportsRecent seismic events have unequivocally highlighted the susceptibility of fault-crossing bridges to the synergistic effects of ground surface vibrations on either side of the fault plane and the tectonic dislocations arising from fault-induced surface ...

Investigation of Sediment in the reservoir on Seismic Damage of Concrete Gravity Dam in the Near-Fault and Far-Fault Ground Motions [PDF]
Journal of Structural and Construction Engineering, 2020 Sediment in the dam’s reservoir has a significant role on mitigation of dynamic response of concrete gravity dams and also the seismic response of dams in near-field motion can be considerably different from those observed in the far field and the near ...

Relationship Between Asperities and Velocity Pulse Generation Mechanism
Frontiers in Earth Science, 2022 Near-fault ground motion records often capture instances of pulse-like behavior, where a burst of energy is expressed as large wave amplitude that occur over short time.

Near fault and far fault seismic analysis of concrete gravity dam [PDF]
Journal of Hydraulic Structures, 2020 Ground motions records of the past higher magnitude (Mw>5) earthquakes have indicated that ground motions recorded at the closest distance of the near-fault are very different from those recorded from a higher distance from the site of the far-fault ...

Seismic performance of frame‐bent structures subjected to near‐fault ground motions
The Journal of Engineering, 2021 Reinforced concrete frame‐bent structures are one of the structural forms commonly used in industrial factory buildings. In order to study the seismic behaviour of frame‐bent structures located near fault areas, eight pulse‐like, eight non‐pulse near ...

Seismic Response Analysis of a Curved Bridge under Near-Fault and Far-Field Ground Motions
Applied Sciences, 2022 To study the influence of near-fault and far-field (FF) ground motions on a curved girder bridge, a 1:10 scale curved bridge shaking table test model was constructed. Three types of ground motions, namely, near-fault pulse (NP), near-fault non-pulse (NN),
