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

Investigation of Uplift force effects on Seismic Damage of Concrete Gravity Dam in the Near-Fault and Far-Fault Ground Motions:Case Study Shafaroud Dam [PDF]
Journal of Structural and Construction Engineering, 2019 Uplift force has significant role on dynamic response of concrete gravity dams and also seismic response of dams in near field motion can be considerably different from those observed in the far field and the near –fault ground motions can cause ...

Finite Fault Source Model for Ground Motion near Fault Zone
IABSE 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 ...

An isolation device for near-fault ground motions
Structural 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 ...

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

Applied 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

Assessment of Near-Fault Ground Motion Effects on the Fragility Curves of Tall Steel Moment Resisting Frames [PDF]
Civil Engineering Infrastructures Journal, 2020 Nowadays it is common to use the fragility curves in probabilistic methods to determine the collapse probability resulting from an earthquake. The uncertainties exist in intensity and frequency content of the earthquake records are considered as the most

Frontiers in Built Environment, 2016 The effect of near-fault ground displacement is a significant factor when structures straddle a fault, because the fault produces both static step-like deformations and dynamic pulse-like ground motions. It has been observed that the static displacements

The Seismic Behavior of Buildings with Flat Slab Systems under Near-Fault Ground Motions
Düzce Üniversitesi Bilim ve Teknoloji Dergisi, 2023 It is well known that structural displacement or ductility demands of structures subjected to near-fault ground motions are generally greater than ordinary ground motions.
