“…Direct motivation for monitoring is also found within bridge management programmes (Yanev 2003) and bridge upgrading projects, where some form of validation is required, which is even made the responsibility of the contractor to ensure the effectiveness of the upgrade. Examples include the Severn and Wye Bridge Refurbishment (Flint & Smith 1992), Tamar Bridge (List 2004) in the UK and Pioneer Bridge, Singapore (Brownjohn et al 2003a,b). In a related sense, the role of monitoring within build, own, operate and transfer contracts can provide investors with confidence in their assessment and subsequent owners' evidence of good condition at the end of the concession.…”

Structural health monitoring (SHM) is a term increasingly used in the last decade to describe a range of systems implemented on full-scale civil infrastructures and whose purposes are to assist and inform operators about continued 'fitness for purpose' of structures under gradual or sudden changes to their state, to learn about either or both of the load and response mechanisms. Arguably, various forms of SHM have been employed in civil infrastructure for at least half a century, but it is only in the last decade or two that computer-based systems are being designed for the purpose of assisting owners/operators of ageing infrastructure with timely information for their continued safe and economic operation. This paper describes the motivations for and recent history of SHM applications to various forms of civil infrastructure and provides case studies on specific types of structure. It ends with a discussion of the present state-of-the-art and future developments in terms of instrumentation, data acquisition, communication systems and data mining and presentation procedures for diagnosis of infrastructural 'health'.

With recent developments, structural engineers are realizing that the quality of their structures is not only bound by economics, function and feasibility, but also aesthetics. The special quality of steel to allow high forces in very slender members is able to meet these new aesthetic requirements. Tough economic competition between the concrete and steel industries has led to a decrease in the number of small and medium‐size steel bridges compared with concrete bridges. The bridges which have been built recently as steel structures, in spite of economic competition, are typically those which span a very long distance with an especially light structure. Examples are the Akashi‐Kaikyo Bridge in Japan, the Storebaelt East Bridge in Denmark and the Normandy Bridge in France. Other recently built steel bridges have been those which have to carry especially high loads over a long span since steel structures combine relatively light weight with high stiffness. Steel bridges worldwide have been growing old. Deciding whether to replace or repair them, mainly depends on their physical condition, especially the degree of fatigue and their state of corrosion. Increasing traffic demands are the main reason for modifications and extensions to existing steel bridges. Seismic evaluation studies recommend the retrofitting of bridges that are at risk. Besides these functional considerations, some bridges are repaired because of their historical and architectural significance; this is a sign of a new perception of bridges as part of our cultural environment.
