The main objective of the present project is to develop an indirect structural health monitoring (SHM) approach, in which one makes use of vibration data collected from sensors installed on vehicles as they traverse the bridge or other infrastructure, rather than from sensors installed directly on the structure. In this project, the authors have not inflicted actual damage to the bridge structure. Instead, they used small, added masses to the bridge deck, dampers, or varying support conditions as proxies. In addition, the authors considered temperature as a parameter since it is well known that bridge properties can vary significantly with temperature changes. Most of the work in the project, especially the feature extraction and classification aspects, focused on data recorded during the experiments with the laboratory models.
Over the past few decades, various fixed scour monitoring instruments have been installed on bridge structures for measuring bridge scour depth. They ...
