Characterization of forward-directivity ground motions in the near-fault region
725
TL;DR: In this article, a simplified parameterization is proposed based on a representative amplitude, pulse period, and number of significant pulses in the velocity-time history to estimate the peak ground velocity and period of the velocity pulse (Tv) of available forward-directivity motions.

2-D FM-IBEM Simulation of broadband ground motions on near-fault mountain-valley coupling site
TL;DR: In this paper , a fast multipole indirect boundary element method (FM-IBEM) was used to efficiently simulate broadband ground motions of complex sites near faults, and the spatial distribution of ground motion at the mountain-valley coupling site located on the hanging wall of the strike-slip fault was quantitatively investigated.

Plastic Input Motion: Transformation for the Response of Yielding Oscillators
TL;DR: In this paper, a transformation method for the response of yielding oscillators to dynamic loading is presented, which employs a translation in the ordinates and the abscissa of the excitation function by means of a pair of parameters uniquely dependent on the yielding resistance and the vibrational characteristics of the system.

A ground motion model for orientation-independent inelastic spectral displacements from shallow crustal earthquakes
Karim Tarbali,Gerard J. O’Reilly +1 more
TL;DR: In this paper , the median and maximum directional inelastic spectral displacements, denoted as Sdi,RotD50 and Sdi-RotD100, respectively, were considered as IMs to develop ground motion models to estimate the arbitrary or geometric mean of the horizontal GM components obtained from the two as-recorded orientations.

TL;DR: A large amount of work has been done in recent years to estimate the distribution of slip on the fault surface during earthquakes as mentioned in this paper, and these slip models are derived from longer period ground motions: strong-motion velocity and displacement, and teleseismic velocity seismograms.
A Mathematical Representation of Near-Fault Ground Motions
TL;DR: In this paper, a simple, yet effective, analytical model is proposed for the representation of near-field strong ground motions, which can be used to analyze empirical observations that are based on available near-source records.

Near‐source ground motion and its effects on flexible buildings
TL;DR: In this article, the authors simulated a Mw7.0 earthquake on a blind-thrust fault and found that flexible frame and base-isolated buildings would experience severe nonlinear behavior including the possibility of collapse at some locations.
