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.

Review of Natural Hazard Risks for Wind Farms
TL;DR: In this article , a review of the risks to wind turbines from earthquakes, strong wind, hurricanes, tsunamis, and lightning is presented, and the structural failure of the blades, towers, and foundations in response to these hazards is investigated.
Inelastic Demand Spectra of Bi-Linear Models for Capacity Spectrum Method and Response of Simple Structures under Near-Source Records
John X. Zhao,Jian Zhang +1 more
TL;DR: In this paper, the authors extended the conventional demand spectra to bi-linear models, where a constant viscous damping coefficient for a single-degree-of-freedom (SDF) structure is calculated from the tangent stiffness and the damping ratio is set at 5% in both elastic and yield phases.

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.
