Identification of pulse-like ground motions using artificial neural network
Earthquake Engineering and Engineering Vibration, 2022For more than 20 years, the concept of near-fault pulse-like ground motion has been a topic of great interest due to its distinct characteristics, particularly due to directivity or fling effects, which are hugely influenced by the rupture mechanism. These unexpected characteristics, along with their effective frequency, energy rate, and damage indices,

Response of buildings to near-field pulse-like ground motions
Earthquake Engineering and Structural Dynamics, 1999Ground motions affected by directivity focusing at near-field stations contain distinct pulses in acceleration, velocity, and displacement histories. For the same Peak Ground Acceleration (PGA) and duration of shaking, ground motions with directivity pulses can generate much higher base shears, inter-storey drifts, and roof displacements in high-rise ...

An improved energy‐based approach for selecting pulse‐like ground motions
Earthquake Engineering and Structural Dynamics, 2016SummaryThis study proposes an improved energy‐based approach for quantitative classification of velocity‐pulse‐like ground motions. The pulse amplitude is determined, in its value and in time location, by the amplitude of the half‐cycle pulse having the largest seismic energy.

Smooth Acceleration Spectra for Pulse-Like Ground Motions
Bulletin of the Seismological Society of America, 2020ABSTRACTIdealization of acceleration response spectra is the basis for construction of target spectra for seismic design and assessment of structures. The adequacy of current methods to reasonably idealize (or smooth) the acceleration spectra of pulse-like and nonpulse-like ground motions is examined in this study.

Evaluation of Intensity Measures for Pulse-Like Ground Motions
Advanced Materials Research, 2010The correlation between intensity measures (IM) for pulse-like ground motions and nonlinear deformation demand of single-degree-freedom-systems (SDOF) is researched, and the efficiency of IM is described. Based on dynamic time analysis of SDOF systems subjected to 72 pulse-like ground motions, the present study investigates the variation of the ...

Power responses of a building subjected to pulse‐like ground motions
Earthquake Engineering & Structural Dynamics, 2021AbstractCompared with non‐pulse‐like ground motions, pulse‐like ground motions are usually near‐fault motions with forward directivity or fling‐step effect. These pulse‐like ground motions are characterized by prominent velocity pulses. The impact force caused by such velocity pulses is generally more destructive than the inertia force induced by ...

Inelastic displacement ratio of near‐source pulse‐like ground motions
Earthquake Engineering & Structural Dynamics, 2012SUMMARYNear‐source pulse‐like records resulting from rupture's directivity have been found to depart from so‐called ordinary ground motions in terms of both elastic and inelastic structural seismic demands. In fact, response spectra may be strong if compared with what is expected from common ground motion prediction equations. Moreover, because not all

Simulation of Near-Field Pulse-Like Ground Motion
2012The accurate prediction of ground motions from possible future earthquakes is the first step toward the robust assessment and mitigation of structural damage against earthquake hazards. The modeling of critical or resonant ground motions has been developed by the present authors in several studies.

Explicit determination of the pulse inherent in pulse‐like ground motions
Earthquake Engineering & Structural Dynamics, 2014SUMMARYA new method is presented for the determination of the parameters of the pulse contained in pulse‐like records. The Mavroeidis and Papageorgiou (M&P) wavelet is used for the mathematical representation of the pulse, but the proposed methodology could be modified to cover other types of wavelets as well.
