Seismic Response Analysis of a Curved Bridge under Near-Fault and Far-Field Ground Motions

open access: yesApplied Sciences, 2022
To study the influence of near-fault and far-field (FF) ground motions on a curved girder bridge, a 1:10 scale curved bridge shaking table test model was constructed. Three types of ground motions, namely, near-fault pulse (NP), near-fault non-pulse (NN),

Quantitative Identification of Pulse-Like Ground Motions Based on Hilbert–Huang Transform

open access: yesShock and Vibration, 2021
Aiming to address the problem of pulse-like ground motions being difficult to identify, this paper refines the Baker’s wavelet-based pulse-like ground motions identification method, followed by a new pulse-like ground motion identification method based ...

Finite Fault Source Model for Ground Motion near Fault Zone

open access: yesIABSE Congress Reports, 2022
<p>Ground motion is categorized into near fault zone and across fault zone where impulsive component is included. The impulsive component usually causes larger damage than that by far-fault ground motion. To build a Benchmark model platform for cable-stayed bridges across-fault region for comparative analysis, the paper proposes a way combining ...

Seismic Energy Response of SDOF Systems Subjected to Long-Period Ground Motion Records

open access: yesAdvances in Civil Engineering, 2021
To provide an important reference for the energy-based seismic design of long-period structures, the elastoplastic dynamic analysis program is employed to study the seismic energy response of single-degree-of-freedom (SDOF) systems under two types of ...

Seismic Response of Skewed Integral Abutment Bridges under Near-Fault Ground Motions, Including Soil–Structure Interaction

open access: yesApplied Sciences, 2021
Studies on the seismic response of skewed integral abutment bridges have mainly focused on response under far-field non-pulse-type ground motions, yet the large amplitude and long-period velocity pulses in near-fault ground motions might have significant

An isolation device for near-fault ground motions

open access: yesStructural Control and Health Monitoring, 2013
Seismic isolation is an appreciable control strategy that reduces the vibrations of structural and nonstructural systems induced by strong ground motions. However, under near-fault (NF) ground motion, the seismic isolation devices might perform poorly because of large isolator displacements caused by long-period large velocity and displacement pulses ...
