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.

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

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

Optimal Seismic Intensity Measure Selection for Isolated Bridges under Pulse-Like Ground Motions
Advances in Civil Engineering, 2019 Isolated bridges are commonly designed in the near-fault region to balance excessive displacement and seismic force. Optimal intensity measures (IMs) of probabilistic seismic demand models for isolated bridges subjected to pulse-like ground motions are ...
