Paper Abstract

Packaged FBG (optical fiber Bragg Grating) strain sensor with good properties of high durability, low cost and reliable installation is in the great need of practical long-term Structural Health Monitoring (SHM) system for civil insfrastructures, especially for those under harsh environment, such as corrosion, high fatigue, etc. Aiming at the practical applications of FBG in such areas, 2 kinds of low cost strain sensors, prototype-packaged FBG sensor and embracing slice packaged FBG sensor, for steel rebar and small cable are developed. And their sensing properties of the sensors under dead load have been tested. The experimental results show good feasibility and advantages of such kinds of sensors for steel rebar or cable strain measurement for practical civil infrastructures under harsh conditions.
