Lidar-Based Vibration Monitoring for Assessing Safety of Damaged Bridges

Currently, most bridge inspections are conducted visually by trained experts to identify damaged areas or components. While fairly rapid to conduct and cost-effective to implement, there are a number of limitations and drawbacks. Therefore, there is a critical need for high-quality engineering data to be collected efficiently during routine bridge inspections and following unanticipated loads (e.g., vehicular collision). The primary objective of this project is to develop a methodology for acquiring vibration measurements using terrestrial laser scanners and to develop an algorithm to extract key engineering data from these measurements, such that improved structural health information can be utilized for decision-making.
