WG4: Case Studies Portfolio

Working Group topic description and achievements

The alignment of the developed insights of WG 1-3 to practical cases and applications is of utmost importance to demonstrate the potential and practical relevance of Value of Information (VoI) analysis. In this working group relevant application cases have been identified and analysed throughout the progress of the Action. Here, it was built upon a substantial portfolio of previously performed case studies within the Action network. The case studies did highlight which combinations of techniques of SHM can be expected to be feasible under which conditions with respect to the precision and instrumentation of the monitoring techniques. In selecting them, the Action did review carefully the problems faced by the various European infrastructure sectors, in order to focus attention in those areas where societal requirements and expectations are affected. Engagement with infrastructure owners/managers was actively pursued in this respect.

The following relevant application areas have been covered:

• Bridges
• Wind energy converters
• Offshore structures
• Dam structures

The case studies did encompass a model to quantify the infrastructure functionality (such as e.g. power production for a wind park), component failure and/or structural collapse in conjunction with strength deterioration mechanisms, such as e.g.:

• Metal fatigue
• Corrosion
• Overload
• Timber decay
