摘要

Structural Health Monitoring (SHM) systems can serve many purposes, by efficiently and reliablyrnproviding great quantities of data in relation to any variable of a structure’s condition orrnperformance. One such purpose is the provision of the detailed information that may be required inrnassessing a bridge’s condition or structural performance, supplementing the more limitedrnknowledge that can be obtained from traditional inspection methods alone. Examples of the use ofrnSHM systems for this purpose are presented, demonstrating how this approach can enable a detailedrnunderstanding of a structure’s performance to be developed – for instance, in providing the datarnrequired by advanced structural models, and confirming hypotheses relating to the suspectedrncondition and its causes. Thanks to the in-depth understanding of the structure’s performance thatrncan be achieved, such systems not only offer an attractive means of completing a bridge inspection,rnbut can further help the service life of a structure to be lengthened and its life-cycle costs to bernreduced.
