Strong ground motion close to a fault can be expected to be very large, so its estimation is essential for human safety. Although a few strong-motion data exist for the west Eurasian region, we proposed in a previous work [Berge-Thierry et al., 2003] an attenuation relation for spectral acceleration using strong-motion data recorded in west Eurasia ...

Response spectrum of seismic design code for zones lack of near-fault strong earthquake records
Acta Seismologica Sinica, 2007It was shown from the study on the recently near-fault earthquake ground motions that the near-fault effects were seldom considered in the existing Chinese seismic code. Referring to the UBC97 design concept for near-fault factors, based on the collected world-widely free-site records of near-fault earthquakes ground motions classified by earthquake ...

Journal of Building Engineering, 2019
Abstract This study aims to investigate the performance of a tuned mass damper (TMD) in mitigating the dynamic response of buildings to far- and near-fault earthquake records including soil–structure interaction (SSI) effects. The selected records ensure near-fault with forward directivity (FD) and near-fault with fling.

Soil Dynamics and Earthquake Engineering, 2018
Abstract Most current baseline correction methods for near-fault ground motion records focus on eliminating and minimizing baseline errors and obtaining true ground motion records that are in accordance with GPS-measured coseismic displacements. Though these methods can recover true ground motions, the single value of ground permanent displacement ...

Study on elastic response of structures to near-fault ground motions through record decomposition
Soil Dynamics and Earthquake Engineering, 2010Accelerograms recorded near active faults have some important characteristics that make them different from those recorded in far-fault regions. High-frequency components in acceleration records and long-period velocity pulses are among notable specifications of such ground motions.

Damage potential of severe long duration acceleration pulses in near-fault records
, 2002 The effects of long period pulses are investigated by computing energy and displacement demand quantities for elastic and inelastic SDOF systems subjected to both records obtained recently in near-fault areas in forward directivity conditions and a series of idealized pulses equivalent to near-fault ground motions.

Ideal-Pulse-Based Strong-Motion Duration for Multi-Pulse Near-Fault Records
Bulletin of the Seismological Society of America, 2023ABSTRACT Serious damage to near-fault structures is caused mainly by velocity pulses in a ground motion, hence, the necessity to develop a pulse-related definition of strong-motion duration to adequately describe the intensity of near-fault ground motion.

Rupture phase in near-fault records of the 2023 Turkey Mw 7.8 earthquake
2023Understanding and deciphering wiggles especially coherent phases from seismograms have been a long endeavor to understand the earth structure and earthquake source. However, coherent phases directly associated with earthquake rupture propagation have not been available due to the lack of continuous near-fault observations.

A VARIATIONAL APPROACH FOR ENERGY-BASED ANALYSIS OF NEAR-FAULT PULSE-LIKE SEISMIC RECORDS
Proceedings of the 7th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2019Near-fault earthquakes often exhibit a pulse in the velocity time-history that mainly occurs in the strike-normal direction at locations towards which the earthquake rupture has propagated. The extraction of the dominant impulsive component embedded into such kind of seismic records and the proper consideration of the other signal modes are critical ...
