Multi-pulse characteristics of near-fault ground motions
Soil Dynamics and Earthquake Engineering, 2020Abstract Multi-pulse characteristics of near-fault ground motions, such as the number of inherent pulses, pulse periods, and amplitudes, have notable influences on the response of structures. To investigate these important parameters, an automatic detection procedure, which is conducted on the rough pulse signal that is extracted by the HHT method ...

Spatial distribution of near-fault ground motion
Acta Seismologica Sinica, 2004Near-fault strong ground motion of strike-slip and dip-slip of vertical and inclined rectangular fault in half-space and layered half-space is analyzed by dislocation source model. The Fourier spectra ratio of ground motion is adopted to study the characteristics of near-fault ground motion.

Effects of near-fault pulse-like ground motions on seismically isolated buildings
Journal of Building Engineering, 2022 Forward-directivity effects create distinct velocity pulse in the fault-normal direction of near-fault ground motions. It has been shown that this pulse period governs the structural response of fixed base buildings.

Finite Fault Source Model for Ground Motion near Fault Zone
IABSE Congress Reports, 2022<p>Ground motion is categorized into near fault zone and across fault zone where impulsive component is included. The impulsive component usually causes larger damage than that by far-fault ground motion. To build a Benchmark model platform for cable-stayed bridges across-fault region for comparative analysis, the paper proposes a way combining ...

Dominant pulse simulation of near fault ground motions
Earthquake Engineering and Engineering Vibration, 2013In this study, a new mathematical model is developed composed of two parts, including harmonic and polynomial expressions for simulating the dominant velocity pulse of near fault ground motions. Based on a proposed velocity function, the corresponding expressions for the ground acceleration and displacement time histories are also derived. The proposed

Automated parameterization of velocity pulses in near‐fault ground motions
Earthquake Engineering & Structural Dynamics, 2023AbstractProper parameterization of near‐fault ground motions is of critical importance in earthquake engineering, and this process is traditionally performed by directly fitting an analytical pulse model to the original motion. Yet such a process is usually limited by the trial‐and‐error procedure, which is strongly dependent on the initial guesses and

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
