Stochastic model for simulation of near‐fault ground motions [PDF]

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 vector‐valued intensity measure for near‐fault ground motions

Earthquake Engineering and Structural Dynamics, 2020
SummaryNear‐fault ground motions containing high energy and large amplitude velocity pulses may cause severe damage to structures. The most widely used intensity measure (IM) is the elastic spectral acceleration at the fundamental period of the structure (Sa(T1)); however, Sa(T1) is not a sufficient IM with respect to the effects of the pulse‐like ...

Characterization of forward-directivity ground motions in the near-fault region

Soil Dynamics and Earthquake Engineering, 2004
Abstract Ground motions close to a ruptured fault resulting from forward-directivity are significantly different than other ground motions. These pulse-type motions can place severe demands on structures in the near-fault region. To aid in the characterization of these special type of ground motions, a simplified parameterization is proposed based on

Multifractal characteristic analysis of near-fault earthquake ground motions

Soil Dynamics and Earthquake Engineering, 2015
Abstract This study aims to reveal the multi-scaling behavior and quantify the irregularity of near-fault earthquake ground motions from a new perspective of multifractal theory. Based on multifractal detrended fluctuation analysis, the multifractal characteristic parameters of acceleration time series for typical near-fault ground motions are ...
