A moderate earthquake ground motion with moment magnitude (Mw) 6.4 took place in the
North-Western area of Iran on August 11, 2012, which was followed by an aftershock (Mw …

This study examines the response of three-dimensional (3-D) steel moment-resisting
buildings having 3-, 9-, and 20-story height under bi-directional attack of real seismic …

Here, the generalized inversion of S-wave amplitude spectra is employed for deriving the
site response and S-wave attenuation (quality factor) in the northwest region of Iran. A total …

For regional hazard analysis or engineering applications, it is necessary to simulate a group
of correlated ground motions containing information from given recordings. A new method is …

The effects of aftershocks on civil structures have called the attention of the earthquake
engineering community mainly in the last two decades. However, neither seismic design …

The ground motion characteristics are essential for understanding the structural seismic
response. In this paper, the time-frequency analytical method is used to analyze the time …

This manuscript investigates the bias introduced by scaling aftershock ground motions when
evaluating the performance of structures subjected to earthquake sequences. The study …

In this study, effects of two types of velocity pulses: visible acceleration pulses (accpulses)
and succession of high-frequency one-sided acceleration spikes (nonaccpulses) are …

The Coulomb stress changes imparted by the 2012 Varzaqan-Ahar earthquake doublets to
the surrounding area have been examined and correlated with the spatial distribution of the …

The characteristics of aftershocks can be quite different from those of mainshocks. However,
most of the works in the past have generally focused on the aftershocks of strong …
