Fiber bragg grating ( FBG ) sensor is a promising measurement technology for strain monitoring in civil engineering. Techniques of installation for FBGs have been explored, and it has been successfully used in construction monitoring of Jiangsu Post Mansion. The monitoring result shows that FBGs are very stable and reliable, and can be used to form distribution measurement systems. So FBG strain sensor is more superior to the conventional strain gauge.
