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.

Seismic Design Parameters Derived from Typical Near-Fault Strong Motions
TL;DR: In this article, features of ground motion pseudo-velocity response spectra are examined by considering the influence of site conditions, and BNPVS values of soil sites are larger than those of rock sites at normalized period T/Tv less than about 0.7.

- 01 Jan 2017
TL;DR: In this article, the cumulative Park-Ang damage index has been used for comparing the damage potential brought about by the two acceleration components of ground motions that are normal to the fault direction or parallel to it.

Modification of Empirical Strong Ground Motion Attenuation Relations to Include the Amplitude and Duration Effects of Rupture Directivity
TL;DR: In this article, the authors developed modifications to empirical strong ground motion attenuation relations to account for the effects of rupture directivity on strong motion amplitudes and durations, based on an empirical analysis of near-fault data.

Paul Somerville,Kojiro Irikura,Robert W. Graves,Sumio Sawada,David J. Wald,Norman A. Abrahamson,Yoshinori Iwasaki,Takao Kagawa,Nancy F. Smith,Akira Kowada +9 more
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.
