Package and installation of embeddable fiber optic sensors

The issues related with design of pre-embedded white light interferometric fiber optic steel, epoxy and concrete bar sensors for use in concrete structures in construction are discussed in this paper. The shapes are designed as spindle for steel and epoxy bar sensors and the simple cylinder or rectangular shape has been used in the cement-based concrete bar sensor. The manufacture procedures of the pre-embedded fiber optic sensors are described in detail. Finally, the issues on the installation of the fiber optic pre-embedded bar sensor into host structures are also considered. (C) 2009 Elsevier Ltd. All rights reserved.
