Near-Fault Ground Motion Effects on Simple Structures
Journal of Structural Engineering, 2001Ground motion records obtained from sites at known locations relative to earthquake faults were used to study near-fault (NF) ground shaking effects on the inelastic response of simple structures. The structures were idealized as single-degree-of-freedom oscillators with periods ranging from 0.05 to 3.0 s, a damping ratio of 2%, and target ductilities ...

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

Representation of near-fault pulse-type ground motions
Earthquake Engineering and Engineering Vibration, 2005Near-fault ground motions with long-period pulses have been identified as critical in the design of structures. To aid in the representation of this special type of motion, eight simple pulses that characterize the effects of either the fling-step or forward-directivity are considered.

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.

Stochastic model for simulation of near‐fault ground motions
Earthquake Engineering & Structural Dynamics, 2016SummaryA 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 ...

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

Can Simple Pulses Adequately Represent Near-Fault Ground Motions?
Journal of Earthquake Engineering, 2011This article investigates the importance of higher modes in the elastic response of tall buildings subjected to near-fault ground motions. Building structures modeled as generic frames are analyzed using a large set of forward-directivity affected pulse-like ground-motion records.

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 ...

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 ...
