Spatial distribution of near-fault ground motion

Acta Seismologica Sinica, 2004
Near-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.

Near-fault and far-fault ground motion effects on cable-supported bridges

Procedia Engineering, 2017
In this paper a cable-stayed bridge and a suspension bridge with closer main span lengths are considered and the bridge responses obtained from the near-fault and far-fault ground motion cases are compared for both bridge models to underline the relative

Multi-pulse characteristics of near-fault ground motions

Soil Dynamics and Earthquake Engineering, 2020
Abstract 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 ...

Dominant pulse simulation of near fault ground motions

Earthquake Engineering and Engineering Vibration, 2013
In 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, 2023
AbstractProper 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

Stochastic model for simulation of near‐fault ground motions

Earthquake Engineering & Structural Dynamics, 2016
SummaryA parameterized stochastic model of near‐fault ground motion in two orthogonal horizontal directions is developed. The major characteristics of recorded near‐fault ground motions are represented. These include near‐fault effects of directivity and fling step; temporal and spectral non‐stationarity; intensity, duration, and frequency content ...

A Mathematical Representation of Near-Fault Ground Motions

Bulletin of the Seismological Society of America, 2003
A 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

2014
In 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
