POWER RESPONSES OF A BUILDING UNDER THE EXCITATION OF PULSE-LIKE GROUND MOTIONS
2nd Croatian Conference on Earthquake Engineering ‒ 2CroCEE, 2023In 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, 2018Abstract 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, 2010The 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 AmericaABSTRACT 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.

Earthquake Engineering & Structural Dynamics, 2018
SummaryPulse‐like records are well recognized for their potential to impose higher demands on structures when compared with ordinary records. The increased severity of the structural response usually caused by pulse‐like records is commonly attributed to the spectral increment around the pulse period.

Detection of pulse-like ground motions based on continues wavelet transform
Journal of Seismology, 2010This paper implements a quantitative approach to detect pulse-like ground motions based on continues wavelet transform, which is able to clearly identify sudden jumps in time history of earthquake records by considering contribution of different levels of frequency.

Overturning of Freestanding Cylindrical Structures under Pulse-like Ground Motions
IABSE Reports<p>This paper focuses on predicting the seismic overturning of freestanding cylindrical structures. Idealized cylinders of different sizes and slenderness are excited by synthetic pulse-like ground motions. A total of 245000 results are summarized in the form of the overturning spectrum.

A classification method for pulse-like ground motions based on S-transform
Natural Hazards, 2016This article presents a new identification procedure to detect pulse-like ground motion based on the S-transform. The S-transform is utilized as an effective tool for time-frequency representation of ground motions. It is shown that plots of the S-transform in the time-frequency domain named as the S-feature provide useful information for initial ...
