A Damage Detection Technique Using Bridge Influence Surfaces for Structural Health Monitoring of Bridges
Structural health monitoring (SHM) of bridges is of paramount importance as they serve the necessity of safeguarding the crucial transportation networks. Damage detection is one of the major tasks in structural health monitoring. In this paper, a technique to detect and locate the damage in the bridge structure is presented. The proposed technique employs the bridge influence surfaces constructed from the responses of the structure collected at limited points. The changes in the influence surfaces under healthy state and any unknown state of the bridge are used to evaluate the damage index. The traffic loads at any instant of time are simulated as point loads at random locations. Influence surfaces for acceleration measurement are considered in a novel way in this study. A single span T-beam slab bridge is used as a numerical example to showcase the efficiency of the proposed technique to identify the presence and the location of damage. The study carried out implies that these damage indices can serve as a reliable means for detecting and locating the damages on the bridges. This technique can also be used for vision-based SHM.
