Structural Health Monitoring of Road Infrastructures Based on FBG Sensor Network

Abstract

We present an architecture for road vibration monitoring based on Fiber Bragg Grating (FBG) sensor interrogation. The deployed network of FBG sensors allows the estimation of fiber elongation and sensor displacement in the presence of an external factor like strain. The Brown Road Bridge is used as a real-world study case to examine the designed vibration monitoring architecture’s performances. In our simulation, we use real fbg sensor displacement signals collected from sensors during an earthquake.
