Performance Warning of Bridges under Train Actions through Equivalent Frequency Response Functions
Publisher: ASCE
Abstract: Structural health monitoring of bridges based on train-induced vibrations has attracted extensive attention and takes advantage of the high-magnitude and regularly spaced features of trainloads. However, the monitoring ...
Automated Eigensystem Realization Algorithm for Operational Modal Identification of Bridge Structures
Publisher: American Society of Civil Engineers
Abstract: The subject of vibration-based structural health monitoring (SHM) has attracted increasing attention, especially in the field of civil engineering. However, the development of these monitoring processes is not a simple ...
Modal Identification of High-Speed Railway Bridges through Free-Vibration Detection
Publisher: ASCE
Abstract: In the dynamic characteristic analysis of high-speed railway bridges, free-vibration responses after a train passes are valuable for modal identification. However, distinguishing between free- and forced-vibration segments ...
