Journal ArticleDOI
Fractal dimension analysis of higher-order mode shapes for damage identification of beam structures
TL;DR: In this paper, the affine transformed mode shape facilitates the fractal dimension analysis to yield an effective damage feature, in which an abruptly risking peak clearly characterizes the location and severity of the damage.
Journal ArticleDOI
Measuring bridge frequencies by a test vehicle in non-moving and moving states
TL;DR: It was found that the vehicle in the non-moving state can catch more bridge frequencies than in the moving state, and the contact-point response performs better than the car-body response, which can be used to detect the first few frequencies of the bridge, including the torsional frequency.
Journal ArticleDOI
State-of-the-Art of Vehicle-Based Methods for Detecting Various Properties of Highway Bridges and Railway Tracks
TL;DR: The vehicle scanning method (VSM), an indirect approach for bridge measurement, has attracted intensive attention since it was proposed and is currently being applied to bridge measurement in China.
Journal ArticleDOI
A multi-scale pseudo-force model in wavelet domain for identification of damage in structural components
TL;DR: In this article, a multi-scale pseudo-force model over wavelet domain was developed for vibration-based damage identification, by canvassing damage-caused local perturbance to dynamic equilibrium characteristics of a structural component.
Journal ArticleDOI
