Joint development in perturbed stress fields near faults
Journal of Structural Geology, 1992Abstract 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
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

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.

Effects of Near-Fault Ground Shaking on Sliding Systems
Geotechnical Earthquake Engineering and Soil Dynamics IV, 2008A numerical study is presented for a rigid block supported through a Coulomb friction contact surface on a horizontal or an inclined plane, and subjected to horizontal or parallel excitation. The latter is described with idealized pulses and near-fault seismic records strongly influenced by forward-directivity or fling-step effects (from Northridge ...

Effects of Near-Fault Ground Shaking on Sliding Systems
Journal of Geotechnical and Geoenvironmental Engineering, 2009A numerical study is presented for a rigid block supported through a frictional contact surface on a horizontal or an inclined plane, and subjected to horizontal or slope-parallel excitation. The latter is described with idealized pulses and near-fault seismic records strongly influenced by forward-directivity or fling-step effects (from Northridge ...

Near‐fault effects on residual displacements of RC structures
Earthquake Engineering & Structural Dynamics, 2016SummaryResidual displacements of single‐degree‐of‐freedom systems due to ground motions with velocity pulses or fling step displacements are presented as a function of period T and of its ratio to the pulse period Tp. Four hysteretic behaviors are considered: bilinear elastoplastic, stiffness‐degrading with cycling, stiffness‐cum‐strength degrading ...

The Vertical and Horizontal Spectra of Near-Fault Ground Motions
Applied Mechanics and Materials, 2012Based on the horizontal and vertical components of a set of 30 acceleration records obtained from 10 near-fault earthquakes, the horizontal and the vertical response spectra are established, and have been compared with each other in this study. Statistical analyses show that, for the selected 30 acceleration records, the maximum mean of vertical ...
