“…A number of bridges have been successfully integrated with the fibre optic sensing system in order to the monitor static and dynamic response on bridge decks and columns [9][10][11][12][13][14][15]. It has been reported that the physical quantities which are able to be determined by fibre optic sensors include temperature, acceleration, corrosion, inclination, and crack [9].…”

“…It has been reported that the physical quantities which are able to be determined by fibre optic sensors include temperature, acceleration, corrosion, inclination, and crack [9]. In recent years, there has been an increasing number of research [10][11][12][13][14][15] towards the structural health monitoring (SHM) of bridges using FBG sensors due to its several practical advantages. Chan et al [15] reported that FBG sensors have been successfully integrated in the SHM system of the Tsing Ma Bridge (the world longest suspension bridge) to monitor several key parts including hanger cable, rocker bearing and truss girders.…”

“…One of the more widely used fiber optic sensors is the Fiber Bragg Grating (FBG) sensor, which can be multiplexed, meaning that multiple measurements from a single fiber can be made (Kister et al 2007). It has been found, however, that fiber optic sensors can also have problems with random drift and must be periodically recalibrated (Farhey 2006).…”

Recent structural failures such as the I-35W Mississippi River Bridge in Minnesota have underscored the urgent need for improved methods and procedures for evaluating our aging transportation infrastructure. This research seeks to develop a basis for a Structural Health Monitoring (SHM) system to provide quantitative information related to the structural integrity of metallic structures to make appropriate management decisions and ensuring public safety.This research employs advanced structural analysis and nondestructive testing (NDT) methods for an accurate fatigue analysis. Metal railroad bridges in New Mexico will be the focus since many of these structures are over 100 years old and classified as fracture-critical. The term fracture-critical indicates that failure of a single component may result in complete collapse of 4 the structure such as the one experienced by the I-35W Bridge. Failure may originate from sources such as loss of section due to corrosion or cracking caused by fatigue loading. Because standard inspection practice is primarily visual, these types of defects can go undetected due to oversight, lack of access to critical areas, or, in riveted members, hidden defects that are beneath fasteners or connection angles. Another issue is that it is difficult to determine the fatigue damage that a structure has experienced and the rate at which damage is accumulating due to uncertain history and load distribution in supporting members. A SHM system has several advantages that can overcome these limitations. SHM allows critical areas of the structure to be monitored more quantitatively under actual loading. The research needed to apply SHM to metallic structures was performed and a case study was carried out to show the potential of SHM-driven fatigue evaluation to assess the condition of critical transportation infrastructure and to guide inspectors to potential problem areas. This project combines the expertise in transportation infrastructure at New Mexico State University with the expertise at Sandia National Laboratories in the emerging field of SHM.5

“…Their relatively small size, ease of use and potential to be multiplexed over the long lengths that represent many bridges make wider tests of their suitability for specific applications very important. Over the last 15 years, research groups around the world have instrumented various types of bridges -steel [1], concrete [2] and composite [3] -with various degrees of success. Thus these studies have demonstrated the potential for FOS to give civil engineers access to a wide range of useful information -for example to monitor strain in real time and on the impact of cracking and thus to assess better the health of the structure.…”
