Seismic responses of isolated bridges subjected to near-fault ground motions: simple pulses vs. whole records [PDF]
Frontiers in Built EnvironmentVelocity pulse with strong energy input is the significant feature of near-fault ground motions. Bridges close to or passing across seismic faults may suffer from higher failure risk, which is inseparable from the influence of velocity pulse.

Near fault and far fault seismic analysis of concrete gravity dam [PDF]
Journal of Hydraulic Structures, 2020 Ground motions records of the past higher magnitude (Mw>5) earthquakes have indicated that ground motions recorded at the closest distance of the near-fault are very different from those recorded from a higher distance from the site of the far-fault ...

Early Tsunami Detection With Near‐Fault Ocean‐Bottom Pressure Gauge Records Based on the Comparison With Seismic Data [PDF]
Journal of Geophysical Research: Oceans, 2020 AbstractOffshore real‐time ocean bottom networks of seismometers and ocean bottom pressure (OBP) gauges have been recently established such as DONET and S‐net around the Japanese islands. One of their purposes is to practice rapid and accurate tsunami forecasting. Near‐fault OBP records, however, are always contaminated by nontsunami components such as

CivilEng, 2023 Seismic isolation is a powerful tool for mitigating seismic risk and improving structural performance. However, some parameters, such as earthquake inputs and soil characteristics, influence the technology’s performance. This research aims to investigate the effects of soil–structure interaction (SSI) with regard to different moderate earthquakes ...

ON THE USE OF INSTANTANEOUS POWER FOR NEAR-FAULT RECORD MODIFICATION [PDF]
Proceedings of the 8th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2021 The current seismic design and assessment procedures describe the seismic demand in terms of elastic spectral accelerations, which may not be adequate to capture the destructive effects of near-fault ground motions. The relevant characteristics of near-fault records, such as the presence of a velocity pulse, the pulse amplitude, and the pulse period ...

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
