摘要
In-service structural health monitoring (SHM) of engineering Structures has assumed a significant role ill assessing their safety and integrity. Fibre Bragg grating (FBG) sensors have emerged as a reliable. in situ, non-destructive tool for monitoring, diagnostics and control ill Civil Structures. The versatility of FBG sensors represents a key advantage over other technologies ill the structural sensing field. In this article, the recent research and development activities in structural health monitoring using FBG sensors have been critically reviewed, highlighting the areas where further work is needed. A few packaging schemes for FBG strain sensors are also discussed. Finally a few limitations and market barriers associated with the use of these sensors have been addressed. (C) 2008 Elsevier B.V.
