Vibration-based monitoring for calibration of FE models of existing concrete structures

The challenge of managing ageing structures relates in essence to decision making under tight budgetary as well as operational constraints taking into account costs for inspections, repair and upgrading, but keeping in mind human safety. Hence, it is evident that efficiency or optimization in the asset management can result in substantial economic savings. Information on the condition of the structure is the necessary basis for deciding on a multitude of actions which can be taken to ensure safe operation of the structure within its projected lifetime or for prolonging its lifetime. Within the frame of this doctoral research project, it will be investigated how the predictive performance of FE models of existing concrete structures can be improved by calibrating these models based on monitoring data, using both local and global vibration-based monitoring data as well as long-term strain measurements. This research is performed as part of the FWO SBO project lifeMACS, which focuses on developing an integrated and interactive life-cycle methodology for the assessment of existing concrete structures using advanced engineering approaches. Partners in this project are University of Ghent, KU Leuven, and the BBRI.
