DESTinationRAIL (Decision Support Tool for Rail Infrastructure Managers) commenced in May 2015 and represents our first research project under the recently commissioned EU Horizon 2020 (H2020) funding scheme. Funded under the Smart Green and Integrated Transport work Programme, Mobility for Growth Call topic, the project is due for completion in April 2018. The aim of the project is to develop solutions for identifying, analysing and remediating critical rail infrastructure. These solutions will be implemented using a decision support tool, which will allow rail infrastructure managers to make rational investment choices based on reliable data.
ROD-IS, as a partner, are leading the work stream focused on predicting performance of railway bridges on the basis of information received from both actual and virtual SHM installations, feeding the information to the decision support tool and Life Cycle Analysis. Having this capability will enable Owners/Managers to optimise budgets/resources from the perspectives of minimisation of cost for maximised service life performance. The developed methodologies will also facilitate statistical updating of predicted performance on the basis of information received from both actual and virtual SHM installations and therefore feed to the decision support tool and Life Cycle Analysis.
A particular aspect of our work will involve applying the methods developed to a real life case study bridge - the Boyne Valley viaduct in Ireland. Using our expertise in Structural Health Monitoring and live load modelling we devised an optimal configuration of strain gauges and accelerometers for the viaduct, the data from which is being used to carry out an accurate Ultimate Limit State probabilistic assessment of the structure. A weather station was also installed. In addition to the probabilistic assessment we will be conducting a Global dynamic analysis, and crucially, fatigue will also be probabilistically assessed for this 80-year old structure.
