Paper Abstract

Optical fiber Bragg grating (FBG) has been appreciated as prominent high-durable local monitoring sensor and largely applied in structural health monitoring (SHM). However, it is still a big problem how to develop the feasible FBG-based sensors to fully meet the practical SHM for infrastructures. Many recent advances of FBG sensors for SHM in Harbin Institute of Technology, P.R. China are introduced in this paper, which include direct FBG-based sensors, indirect FBGbased sensors; FBG based smart structures, and the applications of FBG sensors in some typical civil infrastructures. Finally, some directions of researches and applications have been recommended. Researches and practical applications show that FBG sensors are becoming one of the key sensors in long-term SHM instead of some conventional electrical sensors.
