Effect of near-fault earthquake on bridges: lessons learned from Chi-Chi earthquake
Earthquake Engineering and Engineering Vibration, 2002The objective of this paper is to describe the lessons learned and actions that have been taken related to the seismic design of bridge structures after the Chi-Chi, Taiwan earthquake. Much variable near-fault ground motion data was collected from the rupture of Chelungpu fault during the Chi-Chi earthquake, allowing the seismic response of bridge ...

Effects of near-fault earthquakes on existing bridge performances
Journal of Civil Structural Health Monitoring, 2020The vertical component of seismic acceleration, often overlooked in ordinary structures, plays a role of primary importance in the case of bridges and viaducts. In particular, it induces both the appearance of uncommon stress conditions on vertical structures, and in some cases, it is a really important factor for bearing device capacity of girders. In

SSI in steel frames subjected to near-fault earthquakes
Soil Dynamics and Earthquake Engineering, 2014Abstract Modern seismic codes are usually associated with far-field earthquakes and generally neglect soil–structure interaction, assuming that omission of this phenomenon leads to conservative results. This study investigates the effect of soil–structure interaction on the inelastic response of two-dimensional steel frames subjected to near-fault ...

Near-Fault Earthquake Ground Motion and Seismic Isolation Design
2023Seismic isolation is one of the most reliable passive structural control techniques with adequately established standards for the earthquake protection of structures from earthquakes. However, it has been shown that the seismic isolation systems may not function the best for the near-fault ground motions, since in the proximity of a capable fault, the ...

Seismic Response of a Viaduct under near-Fault Earthquakes
Applied Mechanics and Materials, 2012Abundant long-periodic components endue near-fault earthquakes with large velocity pulses while the viaducts owe long periodic fundamental period. To explore the seismic response patterns of viaducts under near-fault earthquakes, the paper analyzed the time history response of a viaduct under near-fault seismograms including TCU 1063, TCU 065, El ...

The response of Karnali Bridge, Nepal to near-fault earthquakes
Proceedings of the Institution of Civil Engineers - Bridge Engineering, 2012Seismic records during recent destructive earthquakes such as Northridge (1994), Kobe (1995), Duzce (1999) and Chi-Chi (1999) revealed peculiarities of ground motion near active faults. Those earthquakes indicated that the vertical acceleration can reach values comparable to horizontal acceleration or may even exceed these accelerations.

Multifractal characteristic analysis of near-fault earthquake ground motions
Soil Dynamics and Earthquake Engineering, 2015Abstract This study aims to reveal the multi-scaling behavior and quantify the irregularity of near-fault earthquake ground motions from a new perspective of multifractal theory. Based on multifractal detrended fluctuation analysis, the multifractal characteristic parameters of acceleration time series for typical near-fault ground motions are ...

Near-Fault Baseline Correction Method and Appliction in Wenchuan Earthquake
Applied Mechanics and Materials, 2012To eliminate the drifting in recordings from Ms8.0 Wenchuan earthquake, a modified two segments baseline correction method is brought up and systematic acceptance standard is presented. The method is applied to recordings from Qingping station and Bajiao station, which are closest stations to surface rupture traces. The effect of baseline correction on
