Quantitative Classification of Near-Fault Ground Motions Using Wavelet Analysis
TL;DR: In this paper, a method is described for quantitatively identifying ground motions containing strong velocity pulses, such as those caused by near-fault directivity effects, using wavelet analysis to extract the largest velocity pulse from a given ground motion.

Probabilistic seismic demand analysis using advanced ground motion intensity measures
Polsak Tothong,Nicolas Luco +1 more
TL;DR: In this paper, the authors compare and contrast the use of various advanced scalar versus vector and conventional scalar ground motion intensity measures (IMs) for probabilistic seismic demand analysis (PSDA) to estimate the mean annual frequency of exceeding a specified value of a structural demand parameter (e.g. interstorey drift).

Relationships between Median Values and between Aleatory Variabilities for Different Definitions of the Horizontal Component of Motion
Katrin Beyer,Julian J. Bommer +1 more
TL;DR: In this article, the authors provide the ratios of different horizontal component definitions in relation to the specification of seismic input for dynamic structural analyses, highlighting the importance of consistency between the component definition used to derive the elastic design-response spectrum and the way that biaxial dynamic loading input is prepared.

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.

Empirical Response Spectral Attenuation Relations for Shallow Crustal Earthquakes
TL;DR: In this article, empirical response spectral attenuation relations for the average horizontal and vertical component for shallow earthquakes in active tectonic regions were derived using a database of 655 recordings from 58 earthquakes.

Characterizing Crustal Earthquake Slip Models for the Prediction of Strong Ground Motion
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.
