title = "Smart FBG-based steel tie rod with self-monitoring functionality",
abstract = "Currently, it is difficult to measure the internal forces of steel tie rods under construction and in long-term service. A novel high-durable smart steel tie rod with functionality of self-monitoring was developed by utilizing fiber Bragg grating (FBG) and installation techniques combined with glass fiber reinforced polymer (GFRP). The sensing features for the smart steel tie rod were investigated. The strain obtained from FBG strain sensors shows very good linearity and repeatability when the steel tie rod is under 85\% of its ultimate load. The force calculated from the strain data obtained during the control loading supports those findings, within a 4\% error. This type of smart steel tie rod easily reveals any stage of stress and can be regarded as a potential strain-based load cell for adjacent structures in a harsh environment.",
