Effects of pulse-like ground motions on tunnels in saturated poroelastic soil for obliquely incident seismic waves

Soil Dynamics and Earthquake Engineering, 2023
It has been widely recognised that near-fault ground motions can be distinctly different from far-fault ground motions, in terms of their amplitudes and spectral characteristics, and there are a number of studies investigating the effects of near-fault ...

Smooth Acceleration Spectra for Pulse-Like Ground Motions

Bulletin of the Seismological Society of America, 2020
ABSTRACTIdealization 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, 2021
AbstractCompared 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 ...

Explicit determination of the pulse inherent in pulse‐like ground motions

Earthquake Engineering & Structural Dynamics, 2014
SUMMARYA 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

2012
The 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.

POWER RESPONSES OF A BUILDING UNDER THE EXCITATION OF PULSE-LIKE GROUND MOTIONS

2nd Croatian Conference on Earthquake Engineering ‒ 2CroCEE, 2023
In comparison with far-field (FF) ground motions, near-fault (NF) ground motions with forward directivity or fling-step effect are characterized by large pulses. These pulse-like (PL) ground motions have pronounced coherent pulses in velocity and displacement histories.

Quantification of response spectra of pulse-like near-fault ground motions

Soil Dynamics and Earthquake Engineering, 2018
Abstract This study aims to quantify the acceleration and displacement response spectra of pulse-like near-fault ground motions, which can be further employed to derive the seismic force demands of a structure system or structural member. The spectra are computed based on a set of pulse type ground motions, and the spectral shapes are derived by ...

Deterministic and probabilistic representation of near-field pulse-like ground motion

Soil Dynamics and Earthquake Engineering, 2010
The response and damage assessment of engineering structures under near-field ground motions is currently of great interest. Near-field ground motion with directivity focusing or fling effects produces pulse-like ground motion that has characteristics different from those of ordinary records.

Stochastic Simulation of Pulse-Like Ground Motions Using Wavelet Packets

Bulletin of the Seismological Society of America
ABSTRACT Seismic near-fault ground motions with large amplitudes and long-period velocity pulses can cause significant damage to structures. In this study, a new stochastic model has been developed to simulate pulse-like ground motions for specified earthquake scenarios.
