Bridge Vibration Monitoring

In recent years, engineers and bridge managers have started to deploy structural health monitoring (SHM) systems to supplement visual examinations. SHM employs various sensors, such as accelerometers, strain gages, displacement transducers, acoustic sensors, and GPS systems, to name a few. These instruments remotely and automatically collect structural response data that can be processed to obtain information on the condition of the bridges. SHM can reduce inspection time and costs, provide objective data, and mitigate access difficulties and safety hazards…

In the following, an overview of state-of-the-art techniques and an outline of emerging technologies are presented to ultimately offer a primer on the objectives, methodologies, and potential applications of bridge vibration monitoring.
