Advances in sensor and communication technologies in recent years have led to a surge of interest by researchers and infrastructure managers in structural health monitoring applications in civil engineering. There are numerous published accounts of deployments of sensors on major structures, in particular bridges, around the world. One of the greatest challenges facing the research community is ensuring that the data generated by these systems actually produce useful information that can inform the decision making process involved in designing, building, operating and maintaining critical infrastructure assets. A common complaint from infrastructure owners about SHM systems is that they have invested substantial sums in monitoring systems but more often than not end up with huge volumes of data which have not been converted to useful information.
As a starting point, a clear definition of what information is sought is required when designing any SHM system. Secondly, a realistic understanding of the accuracy and robustness of the sensor technology is required. Thirdly a system for translating the measurements into useful information that relates to the performance of the structure needs to be established.
These issues will be discussed with particular reference to deployments of structural health monitoring systems on bridges in the UK, specifically the Humber Bridge and Ferriby Road Bridge near Hull, Hammersmith Bridge in London and the Nine Wells Bridge in Cambridge. The technologies involved include wireless sensor networks, MEMS sensors, and fibre optic sensors for strain and temperature measurement.
