Abstract
Monitoring the distressing effects on civil structures caused due to harsh environmental conditions, aging, and overloading is very important to assess the strength of the structure and to decide its durability. With the recent development in fiber-optic sensor fields, the fiber-optic sensors play an important role in monitoring the health of the structures by having several advantages over the other conventional sensors like resistance to electromagnetic interference, corrosion. In this article, structural health monitoring of civil structures at elevated temperatures up to about 200 °C is evaluated theoretically and demonstrated experimentally using the fiber Bragg grating (FBG) sensors. The sensor will be embedded in the different materials, the strain sensitivity at the elevated temperatures for different materials will be presented, and experimental results will be calibrated with theoretical calculations.
