Real-time Monitoring Systems for Highway Bridge Constructions

摘要

The civil engineering community is becoming increasingly interested in monitoring structural behavior and in assessing its corresponding integration. Current technology allows Fiber Bragg Grating (FBG) sensors to be easily fabricated and placed in civil structures. In this paper, FBG sensors were installed to investigate the in-situ characteristics of the hydration progress period and the curing process of highway bridge construction. It appeared that FBG sensor was clearly shown to be the smart sensor candidate for function integration and response of a highway bridge during both its construction and service life.
