Liquefaction Potential Assessment for Near Field and Far Field Ground Motion

Lecture Notes in Civil Engineering, 2021
Out of the various seismic hazards, soil liquefaction is a major cause of both losses of life and damage to infrastructures and lifeline systems. For establishment of various important structures, suitable identification, evaluation and analysis of the liquefaction should be done in soil sites.

Vertical ground motion in near field

, 2014
Two questions have puzzled seismologists in the past: if vertical peak accelerations could exceed the horizontal ones and if vertical peaks exceeding 1 g were feasible in the near field. Recordings of vertical accelerations larger than 1 g are very rare, only 7 so far (according to the Strong Motion Virtual Data Center, see Table 1). This is mainly due

Deterministic and probabilistic representation of near-field pulse-like ground motion

Soil Dynamics and Earthquake Engineering, 2010
The response and damage assessment of engineering structures under near-field ground motions is currently of great interest. Near-field ground motion with directivity focusing or fling effects produces pulse-like ground motion that has characteristics different from those of ordinary records.

Near-field ground motion from the Landers earthquake [PDF]

, 1995
In order to investigate near-field ground motions, an important Lucerne Valley record from the Landers earthquake is studied. The Lucerne Valley record was recorded on the Kinemetrics SMA-2/EMA instrument located 2 km from the fault. Since the characteristics of the SMA-2/EMA instrument were not completely understood and the conventional data ...

Displacement and Acceleration Response Spectra for Near Field Strong Ground Motions

, 2002
Generation of a smoothed design response spectra is essential for practical seismic design. This project presents the results of a statistical regression analysis on displacement and acceleration response spectra for near-field strong ground motion earthquake events.

Simulation of Rotational ground motion in the near field region

2020
<p><strong> </strong></p><p>In recent times, seismic rotational motions have received significant attention of seismologists as well earthquake engineers. The measurement of rotational motions is useful not only for the complete characterization of the ground ...

Near-Field Across-Fault Seismic Ground Motions

Bulletin of the Seismological Society of America, 2011
Abstract There are many engineering applications that require an understanding of the nature of strong ground motions adjacent to and spanning across faults. Unfortunately, such near-field observations at distances less than 100 m of fault rupture are few and incomplete.

Dependency of Near-Field Ground Motions on the Structural Maturity of the Ruptured Faults

Bulletin of the Seismological Society of America, 2009
Little work has been undertaken to examine the role of specific long-term fault properties on earthquake ground motions. Here, we empirically examine the influence of the structural maturity of faults on the strong ground motions generated by the rupture of these faults, and we compare the influence of fault maturity to that of other source properties (

Simulation of Near-Field Pulse-Like Ground Motion

2012
The accurate prediction of ground motions from possible future earthquakes is the first step toward the robust assessment and mitigation of structural damage against earthquake hazards. The modeling of critical or resonant ground motions has been developed by the present authors in several studies.

Stochastic geologic effects on near-field ground motions in alluvium

Bulletin of the Seismological Society of America, 1988
Abstract Analysis of accelerograms recorded at the 20 m range from a buried 5-lb detonation in alluvium revealed wide (as large as 20 dB in the amplitude modulus of the Fourier transform) variations in response for frequencies above 35 Hz. Additional experiments were performed which ruled out source asymmetry or instrumental irregularity
