Identification of pulse-like ground motions using artificial neural network
Earthquake Engineering and Engineering Vibration, 2022 For 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,

Evaluation of Intensity Measures for Pulse-Like Ground Motions
Advanced Materials Research, 2010 The 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 ...

A simple and intuitive procedure to identify pulse-like ground motions
Soil Dynamics and Earthquake Engineering, 2017Abstract Near-fault seismic ground motions are frequently characterized by intense velocity and displacement pulses of relatively long periods that clearly distinguish them from typical far-field ground motions. Intense velocity pulse motions can affect adversely the seismic performance of structures.

Inelastic displacement ratio of near‐source pulse‐like ground motions
Earthquake Engineering & Structural Dynamics, 2012 SUMMARYNear‐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

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.

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.
