Abstract

The civil engineering community is becoming increasingly interested in monitoringstructural behavior and in assessing its corresponding integration. In this paper, fiberBragg grating (FBG) sensors were installed to investigate the in situ characteristics of thehydration progress period and the curing process of highway bridge construction. Moreover,the security and serviceability of a bridge can be changed by material proprieties such asshrinkage and creep, which is correlated with the prestressing strain and settlement duringthe support frame removal. The response and effectiveness of the schedule at every stepduring the prestressing process, and during the support frame removal, were also examined.It appeared that an FBG sensor was clearly shown to be a smart sensor candidate forfunction integration and response of a highway bridge during both its construction andservice life.
