Strategies for low limit maintenance thresholds and condition states for bridge structures

Abstract The objectives of asset management are to ensure secure service the objects and/or network, preserve infrastructure capital and maintain function through their life cycle. Maintenance activities should performance future serviceability in such way that an adequate level reliability with respect requirements applicable structure under consideration is preserved. Hence low limit maintenance guarantee reliability, safety functionality, availability, maintainability, health security, as well environmental economic at politically agreed service. In order arrange resources, concept condition‐states minimum thresholds widely used context planning many European countries. However, there no uniform approach defining rating setting thresholds. general, national authorities or individual operators using own developments which consequently lead different levels cases, models criteria based on country‐specific experience implementation condition‐based strategies. Moreover, some countries, preventive uses both scheduled strategy, certain measures carried out a manner other planned/fixed intervals. this contribution outcomes IM‐SAFE project, concepts, condition‐state definitions strategies countries will be presented, discussed compared. addition, special focus given apply sustainable develop respecting green deal scopes.
