A Mathematical Representation of Near-Fault Ground Motions
Bulletin of the Seismological Society of America, 2003A simple, yet effective, analytical model is proposed for the representation of near-field strong ground motions. The model adequately describes the impulsive character of near-fault ground motions both qualitatively and quantitatively. In addition, it can be used to analytically reproduce empirical observations that are based on available near-source ...

SIMULATION OF NEAR-FAULT GROUND MOTIONS USING FREQUENCY-DOMAIN DISCRETIZATION
2014In 2008, S. Rezaeian and A. Der Kiureghian introduced a new fully nonstationary stochastic model for strong earthquake ground motions. The model employs a parameterized stochastic model, which is based on a modulated Gaussian white noise. In 2010, the same authors used this work as a base for developing a new method for generating a family of synthetic

Residual slip of sliding blocks induced by near‐fault ground motions
Earthquake Engineering & Structural Dynamics, 2016SummaryThe response of a rigid block supported on a horizontally moving foundation through a dry‐friction contact is investigated to near‐fault ground motions. Such motions can be thought of as consisting of a coherent component (‘pulse’) and an incoherent component, which can be described as a band‐limited ‘random noise’.

Damping coefficients for near-fault ground motion response spectra
Soil Dynamics and Earthquake Engineering, 2011Abstract Damping coefficients are frequently used in earthquake engineering as a simple way to adjust the pseudo-acceleration or displacement response spectra associated with a viscous damping ratio of 5% to the higher values of viscous damping needed for design of structures equipped with base isolation and/or supplemental energy dissipation devices.

Characteristics of near-fault ground motion containing velocity pulses
Acta Seismologica Sinica, 2006There are many reports about the research on near-fault velocity pulses, which focus on the generation of velocity pulse and simplify the velocity pulse so as to be used in the seismic design of structure. However few researches have put emphasis on the characteristics of near-fault ground motions containing velocity pulses, especially the ...

Near-Fault Earthquake Ground Motion and Seismic Isolation Design
2023Seismic isolation is one of the most reliable passive structural control techniques with adequately established standards for the earthquake protection of structures from earthquakes. However, it has been shown that the seismic isolation systems may not function the best for the near-fault ground motions, since in the proximity of a capable fault, the ...

Simulation of Near Fault Ground Motion in Delhi Region
2014Ground motions in the vicinity of the source caused severe damage to structures as evidenced during the past earthquakes (Loma Prieta 1989; Kobe 1995; Chi-Chi 1999). Near fault ground motions are characterized by long period velocity pulse as reported in literature (Somerville, 2005).

A stochastic model and synthesis for near‐fault impulsive ground motions
Earthquake Engineering & Structural Dynamics, 2014SummaryThe orientations of ground motions are paramount when the pulse‐like motions and their unfavorable seismic responses are considered. This paper addresses the stochastic modeling and synthesizing of near‐fault impulsive ground motions with forward directivity effect taking the orientation of the strongest pulses into account. First, a statistical

Fractal characterization and frequency properties of near-fault ground motions
Earthquake Engineering and Engineering Vibration, 2013This study explores the irregularity and complexity of strong earthquake ground motions from the perspective of fractal geometry, and constructs a relation with the frequency content of the ground motions. The box-counting fractal dimensions and five representative period parameters of near-fault ground motions from the Chi-Chi and Northridge ...
