Identification of pulse-like ground motions during the 1994 Northridge Earthquake
IOP Conference Series: Earth and Environmental Science, 2021 Abstract The 1994 Northridge Earthquake is selected as an example to discuss the ability of three pulse-like ground motion identification methods. Wavelet analysis, peak-point method (PPM) and zero velocity point method (ZVPM) are used.

Effects of response spectrum of pulse-like ground motion on stochastic seismic response of tunnel [PDF]
, 2023 It is widely accepted that near-fault pulse-like ground motions potentially cause more severe damage to structures than ordinary ground motions. However, the effects of stochastic pulse-like ground motions on underground structures are not effectively ...

Accounting for directivity-induced pulse-like ground motions in building portfolio loss assessment [PDF]
, 2020 Earthquake-induced pulse-like ground motions are often observed in near-source conditions due to forward-directivity. Recent worldwide earthquakes have emphasised the severe damage potential of such pulse-like ground motions.

A non-separable stochastic model for pulse-like ground motions [PDF]
, 2014 A phenomenological non-separable non-stationary stochastic model is proposed to represent near-fault pulse-like ground motions (PLGMs) by means of a parametrically defined evolutionary power spectrum (EPSD). Numerical data pertaining to ensembles of EPSD compatible realizations and considering statistical analysis of peak elastic and inelastic spectral

Results in Engineering, 2023 Unreinforced masonry (URM) is considered one of the most cost-effective structural typologies for low-rise buildings in seismic regions. Near-field (NF) ground motions are sometimes characterized by high-velocity pulses that are typically more ...

Quantitative bounded method of special long-period ground motions
Magazine of Civil Engineering, 2022 The resonance effect of special long-period ground motions to (super) high-rise buildings is significant, which is likely to cause serious damage to these long-period structures. Therefore, the influence of long-period ground motions cannot be ignored in

Alternate algorithm for characterization of strong velocity pulse in ground motions
, 2023 The identification of pulse-like ground motion is essential in seismic hazard analysis and structural design. The approaches for pulse characterization can be classified into two categories: signal processing based (e.g., wavelet transform, Hilbert Huang
