Near-Field Ground Motion Modal versus Wave Propagation Analysis [PDF]
Shock and Vibration, 2010 The response spectrum generally provides a good estimate of the global displacement and acceleration demand of far-field ground motion on a structure.

Influence of the Seismic Wave Velocity of the Damage Zone on Near-Field Ground Motions
Frontiers in Earth Science, 2021 In burst-prone deep underground engineering, seismic waves generated from a near-field ground motion event may play a critical role in causing localized rockburst damage.

Detection Limits and Near‐Field Ground Motions of Fast and Slow Earthquakes [PDF]
Journal of Geophysical Research: Solid Earth, 2020 AbstractWe investigate theoretical limits to detection of fast and slow seismic events, and spatial variations of ground motion expected from M 6 earthquakes at short epicentral distances. The analyses are based on synthetic velocity seismograms calculated with the discrete wavenumber method assuming seismic velocities and attenuation properties of the

Forces in Mechanics, 2023 This study aims to understand the behaviour of a base isolated l-shaped building under far field and near field earthquake ground motion. A ten-storey l-shaped building was considered for the study and modelled using SAP2000, which is finite-element ...

Assessment of soil amplification effects on the seismic vulnerability of irregular reinforced concrete buildings of varying heights [PDF]
Scientific ReportsEarthquakes pose a significant threat to structures in seismically active regions. It is, therefore, important to understand the factors that influence the vulnerability of buildings.

Pulse-like ground motion simulation using wavelet-based Hilbert transforms [PDF]
مهندسی عمران شریف, 2022 In areas near active faults, ground motions usually show a large pulse in velocity time history. These near-field pulse-like ground motions increase the structural failure and cause extensive damage to structures.

Seismic performance of moment frames under multiple fling-step pulse ground motions
Jurnal Ilmiah SINERGI, 2022 The displacement fling-step pulse seldom signatures near-field earthquake in its ground motions. It is well recognized that the near-field ground motion with velocity pulse amplifies the building drift larger than the regular ground motion.

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 ...
