Evaluation of practical equivalent seismic input methods for fault-crossing bridges considering dynamic and permanent ground displacement [PDF]
Scientific ReportsDuring major earthquakes, fault ruptures frequently lead to significant differences in ground motions across the fault trace. As a result, fault-crossing bridges are subjected to complex seismic demands characterized by the combined effects of transient ...

Buried pipelines with bends: analytical verification against permanent ground displacements [PDF]
Canadian Geotechnical Journal, 2016 Available analytical methodologies for the stress analysis of buried pipelines against large permanent ground displacements (PGDs) apply only to straight pipeline segments. Hence, a new methodology is proposed herein for the analytical computation of pipeline strains in bends of arbitrary angle and radius of curvature, located outside the PGD high ...

Research progress of baseline correction for near-field strong motion accelerogram
地球与行星物理论评, 2022 The baseline drift is often found in strong motion accelerograms, especially in the near-field accelerogram. The small baseline drift in accelerogram will lead to linear drift in the velocity time history obtained through single integration and parabolic

Fling-Step Recovering from Near-Source Waveforms Database
Geosciences, 2021 We present an upgraded processing scheme (eBASCO, extended BASeline COrrection) to remove the baseline of strong-motion records by means of a piece-wise linear detrending of the velocity time history.
