Identification of pulse-like ground motions during the 1994 Northridge Earthquake

open access: yesIOP 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]

open access: yes, 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

Seismic fragility analysis of low-rise unreinforced masonry buildings subjected to near- and far-field ground motions

open access: yesResults 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

open access: yesMagazine 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

open access: yesAdvances 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 ...

Tuned Mass Dampers for Response Reduction of a Reinforced Concrete Chimney Under Near-Fault Pulse-Like Ground Motions

open access: yesFrontiers in Built Environment, 2020
The article investigates response mitigation of a reinforced concrete (RC) chimney subjected to pulse-like near-fault ground motions using tuned mass damper (TMD) schemes. The total height of the chimney is 265 m with a mass of 11,109 ton.
