Quantitative Identification of Pulse-Like Ground Motions Based on Hilbert–Huang Transform
Shock and Vibration, 2021 Aiming to address the problem of pulse-like ground motions being difficult to identify, this paper refines the Baker’s wavelet-based pulse-like ground motions identification method, followed by a new pulse-like ground motion identification method based ...

Pulse-like ground motion simulation using wavelet-based Hilbert transforms [PDF]
مهندسی عمران شریف, 2022 In areas near active faults, ground motions usually show a large pulse in velocity time history. These near-field pulse-like ground motions increase the structural failure and cause extensive damage to structures.

Modeling response spectrum compatible pulse-like ground motion [PDF]
Mechanical Systems and Signal Processing, 2022 The seismic response analysis of near-fault pulse-like ground motions is severely restricted due to the scarcity of pulse-like records. The requirement in regulations that the response spectra of artificial ground motions should be compatible with the ...

Effects of near-fault pulse-like ground motions on seismically isolated buildings
Journal of Building Engineering, 2022 Forward-directivity effects create distinct velocity pulse in the fault-normal direction of near-fault ground motions. It has been shown that this pulse period governs the structural response of fixed base buildings.

Seismic efficiency of self-centering braced frame under near-field pulse-like ground motions [PDF]
مجله مدل سازی در مهندسی, 2018 This research investigates the efficiency of the self-centering steel braced frame equipped with replaceable yielding fuses and post-tensioning cables subjected to far-field records and near-field pulse-like ground motions.
