Near-Fault Shaking Demands on Short Structures

Advanced Technology in Structural Engineering, 2000
Near fault earthquake shaking may cause structures to experience inelastic displacement demands which are significantly greater than that expected from design level earthquakes. This paper describes the inelastic demands for elastic-perfectly plastic single-degree-offreedom oscillators to actual recorded earthquake motions.

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.

Shear Plastic Constitutive Behavior for Near-Fault Ground Motion

Journal of Engineering Mechanics, 2017
AbstractThe analysis of structures subjected to earthquake actions can be carried out by means of several methods with different levels of accuracy, among which the nonlinear dynamics is generally ...

Elastic and Inelastic Near-Fault Input Energy Spectra

Earthquake Spectra, 2018
The main purpose of this study is to develop a reliable model for predicting the input energy spectra of near-fault ground motions for linear elastic and inelastic systems, and to evaluate the effect of damping and lateral strength on energy dissipation demands.

Maximum Spectral Demands in the Near-Fault Region

Earthquake Spectra, 2008
The Next Generation Attenuation (NGA) relationships for shallow crustal earthquakes in the western United States predict a rotated geometric mean of horizontal spectral demand, termed GMRotI50, and not maximum spectral demand. Differences between strike-normal, strike-parallel, geometric-mean, and maximum spectral demands in the near-fault region are ...

Effect of Near-fault Terrain upon Dislocation Modeling

pure and applied geophysics, 1997
—Coseismic surface deformation provides important information needed to determine source rupture geometry and slip distribution as well as to estimate seismic moment. In this study, numerical experiments were designed to analyze and classify how free-surface topography affects surface deformation.

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 ...

Joint development in perturbed stress fields near faults

Journal of Structural Geology, 1992
Abstract Field evidence is presented for complex spatial and temporal perturbations of an otherwise systematic joint pattern around faults from well exposed faulted rock platforms. Joints propagating in perturbed stress fields will curve to follow the directions of the stress field trajectories.

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

Near-Fault Ground Motion Effects on Simple Structures

Journal of Structural Engineering, 2001
Ground 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 ...
