“…-çcot S(t)=Kw e .szn[w.t] (2) The important parameters in relationship with the dynamic characterization of the system are: the natural frequency and the damping. The natural frequency can be obtained through the period of the waveform of the transient response that we have measured: T 24 ms 42 Hz.…”

“…On the other hand, the measurement of different material and structure parameters are readily available, for example, temperature, strain, pressure or load. The use of optical fiber sensors networks into the structure allows diagnosis of the integrity of the material, providing information about the real use of the structure which can be sent to the place in which the measurement system is stored [2] [3]. If the material applied to an aged structure is a composite material with embedded optical fiber sensors, a monitoring of the structure's heath is added to the aged structure reinforcement.…”

In this paper we present the results that have been obtained with an automated electronic instrumentation system for monitoring ofstrain and vibrations in a composite material board with embedded opticalfibers. The objective ofthis study is to provide an electronic instrumentation referencefor the interferometric measurements using opticalfiber sensors. The mainfeatures ofour system are the simultaneous multipoint strain and vibrations measurements which allows us real time data acquisition and processing. In this work we provide results about the naturalfrequency and damping coefficient of the composite material board.

“…In general civil buildings, Fuhr et al [30] installed FOS in a five-storey, 65000 square feet concrete structure, named the Stafford Medical Building of Vermont University, to monitor stresses incurred during the construction phase and monitoring of concrete curing as well as internal crack sensing. Kwon et al [31] used Brillouin-based distributed FOS to measure temperature distribution in a building construction.…”

Structural Health Monitoring (SHM) aims to develop automated systems for the continuous monitoring, inspection, and damage detection of structures with minimum labour involvement. The first step to set up a SHM system is to incorporate a level of structural sensing capability that is reliable and possesses long term stability. Smart sensing technologies including the applications of fibre optic sensors, piezoelectric sensors, magnetostrictive sensors and self-diagnosing fibre reinforced composites, possess very important capabilities of monitoring various physical or chemical parameters related to the health and therefore, durable service life of structures. In particular, piezoelectric sensors and magnetorestrictive sensors can serve as both sensors and actuators, which make SHM to be an active monitoring system. Thus, smart sensing technologies are now currently available, and can be utilized to the SHM of civil engineering structures. In this paper, the application of smart materials/sensors for the SHM of civil engineering structures is critically reviewed. The major focus is on the evaluations of laboratory and field studies of smart materials/sensors in civil engineering structures.

AB STRACT R E S U M I~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. Le d&eloppement d'utilisations pour la technologie (mergeante des fibres optiques peut aider a gdrer la santd des ouvrages en foumissant un p@'l pr&is des contraintes et l'historique des dldments structurels. Uune des applications sp&ialis&s des fibres optiques est l'utilisation du r&eau
