Near-Fault Shaking Demands on Short Structures
Advanced Technology in Structural Engineering, 2000Near 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.

Shear Plastic Constitutive Behavior for Near-Fault Ground Motion
Journal of Engineering Mechanics, 2017AbstractThe 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 ...

SEISMIC RISK ASSESSMENT OF LIFELINES IN NEAR-FAULT AREAS
2017In proximity of a seismogenic source (near-fault or near-source), meaning for maximum distances ranging from about one km to a few tens of km as a function of earthquake magnitude, the ground motion produced by strong earthquakes presents typical characteristics in terms of amplitude, duration and frequency content, and it may be characterised by the ...

Impact of Near-Fault Pulses on Engineering Design
2006This contribution attempts to shed light on the important issues that affect the response of frame structures to near-fault ground motions with forward directivity. There is evidence that ground shaking near a fault rupture is characterized by a small number of pulses with high input energy.

Seismic Response of a Viaduct under near-Fault Earthquakes
Applied Mechanics and Materials, 2012Abundant long-periodic components endue near-fault earthquakes with large velocity pulses while the viaducts owe long periodic fundamental period. To explore the seismic response patterns of viaducts under near-fault earthquakes, the paper analyzed the time history response of a viaduct under near-fault seismograms including TCU 1063, TCU 065, El ...

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 ...

Analysis on the Mechanism for Baseline Drift of near-Fault Accelerograms
Applied Mechanics and Materials, 2012Accelerograms recorded by accelerographs are of fundamental importance in seismic engineering, forming the basis of ground shaking employed for anti-seismic design. By analysis on the general solution of wave equation, this article demonstrated that the ground tilting is related with the ground velocity and displacement histories.

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 ...

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

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.
