SAMCO Final Report 2006 F09 Report on Bridge Management
General question 2: What monitoring type would be the most relevant for you and what would the main requirements be for such monitoring ?.
A number of replies and comments were received to this question. In general the replies specify:
Condition monitoring would be very relevant. This would provide an continu- ously updated status of the structures condition and also establish a track re- cord of the progress towards initiation of the damage and of the damage growth.
Monitoring which is cheap, cost-efficient, reliable and simple would provide a major improvement and enlarge the potential monitoring volume significantly.
Monitoring should include as few parameters as possible, as this reduces the costs and facilitates the data interpretation. The parameters and monitoring positions should be selected so they provide a representative assessment of the structure.
The short term methods (NDT) should be correlated with the long term moni- toring. This would combine the best of the two approaches.
Monitoring should be designed, so it can be combined and compared with the visual and periodic inspections.
A number of more specific needs were also pointed out
6. A strong tool for the analysis of dynamic data would be required, if the data are to be used as an efficient input to the damage predictions.
Monitoring for loss of stress in cables in suspension bridges is needed.
Sensors for monitoring carbonation depth are needed.
