Soil Dynamics and Earthquake Engineering, 2022 Near-fault earthquakes have been largely studied in the last years by paying special attention to the occurrence of a pulse-like horizontal seismic ground motion, and to the related effects on structural systems.

Identification of near-fault multi-pulse ground motion [PDF]
Applied Mathematical Modelling, 2023 The near-fault pulse-like ground motion is of practical importance since it tends to cause severer damage to structures than ordinary ground motion in engineering and helps characterize the seismic source and the kinematic characteristics of the ...

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.

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 ...

On the use of the equivalent linearization for bilinear oscillators under pulse-like ground motion
Engineering Structures, 2018 The equivalent linearization is a well-known simplified approach for estimating the maximum absolute displacement of inelastic systems, being widely adopted in many technical codes and guidelines.

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.

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.
