Abstract

Developing uses for emerging fiber optic technology may help to manage the health of smart structures by providing an accurate strain profile and history of structural members. One specialty fiber optic application is the use of Bragg Gratings, which can measure pointwise the strain. First, practical application of this technology is reported. Next, the accuracy of Bragg Grated fibers was validated and a method to install the delicate fibers in a full size reinforced concrete beam was developed, both in the laboratory and in the field. Finally, remote sensing of the sensors through the Internet is explored.

Résumé

Le développement d’utilisations pour la technologie émergeante des fibres optiques peut aider à gérer la santé des ouvrages en fournissant un profil précis des contraintes et l’historique des éléments structurels. L’une des applications spécialisées des fibres optiques est l’utilisation du réseau Bragg, qui peut mesurer la contrainte par points. L’application pratique de cette technologie est d’abord présentée. Ensuite, la précision des fibres du réseau Bragg a été validée et une méthode pour installer ces fibres délicates dans une poutre de béton renforcée de taille normale a été développée, en laboratoire et sur le site. Enfin, on discute de la détection à distance au moyen d’Internet.
