Shaking Table Test of a Base-Isolated Frame Structure under Near-Fault Ground Motions

Buildings, 2022
A five-story moment frame structural model with a base isolation system was tested on a shaking table. The isolation system comprised both linear natural rubber bearing (LNR) and nonlinear viscous dampers (NLVDs).

Effects of pulse-like ground motions and wavelet asymmetry on responses of cantilever retaining wall

, 2023
Fault-rupture processes produce pulse-like ground motions in near-fault regions. These motions are characterized as large-amplitude long-period pulsing that can cause severe structural damage.

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.

Probabilistic seismic resilience analysis for bridges shocked by nearfault pulse-like ground motions

, 2016
This paper developed a probabilistic approach to estimate the seismic resilience of the shortmedium span bridges shocked by near-fault pulse-like ground motions. The seismic resilience demand of bridges is quantified.

Correlation analysis between ground motion parameters and seismic damage of buildings for near-field ground motions

Natural Hazards Research, 2022
Pulse-like ground motions constitute a significant challenge to the performance of buildings, as they are characterized by long intense velocity, displacement, or acceleration pulses.

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

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

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 ...

The effect of directivity-induced pulse-like ground motions on fracture risk of welded steel column splices [PDF]

, 2019
Recent, worldwide earthquakes have highlighted the destructive potential of near-fault, pulse-like ground motions caused by forward directivity. This study investigates the fracture risk of welded steel column splices (WCSs) in near-fault regions ...

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
