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 ...

Response analysis of hollow core slab bridge with different column heights to near-fault seismic motions. [PDF]
JES: Journal of Engineering SciencesThe near-fault earthquake motions are characterized by influential velocity impulses, and remarkable permanent displacement. Such unique characteristics can substantially change the induced seismic responses of structures.

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 ...

Modification of Random Vibration Theory for the Near-fault Region [PDF]
, 2021 Abstract Standard random vibration theory (RVT) methods for estimating the horizontal spectral acceleration (PSA) amplitudes given the Fourier spectral amplitude (FAS) and ground-motion duration underestimate the PSA values for near-fault ground motions from large magnitudes.

An isolation device for near-fault ground motions
Structural Control and Health Monitoring, 2013 Seismic isolation is an appreciable control strategy that reduces the vibrations of structural and nonstructural systems induced by strong ground motions. However, under near-fault (NF) ground motion, the seismic isolation devices might perform poorly because of large isolator displacements caused by long-period large velocity and displacement pulses ...

Frontiers in Built Environment, 2016 The effect of near-fault ground displacement is a significant factor when structures straddle a fault, because the fault produces both static step-like deformations and dynamic pulse-like ground motions. It has been observed that the static displacements
