On the digital twinning of routine load tests in railway bridges

On the 15th of July, 2022, The ASHVIN team presented a publication in Conference proceedings at International Conference on Bridge Maintenance, Safety and Management 2022 (↗️). This publication is entitled “On the digital twinning of routine load tests in railway bridges. Case study: high-speed railway network, Extremadura, Spain”, and it is co-written by a group of ASHVIN collaborators (Chacon, R.; Posada, H.; Ramonell, C.; Sierra, P.; Rodriguez Gonzalez, A.; Koulalis, I.; Ioannidis, K.; Vrochidis, S.; Tomar, R.; Freitag, S.; Wagmeister, S.; Teodorovic, M.). 

This paper shows the developments in the digital twinning of a set of new High-speed Railway bridges located in South Western Spain. The aim of this digitisation is the generation of twin-driven maintenance planning. This research is performed within the frame of an H2020 European project called ASHVIN, related to using Digital Twins for Design, Construction and Maintenance purposes within the AEC sector. The project provides a series of demo cases for all stages. One of the demo cases is a series of new bridges belonging to a high-speed train network in Extremadura, Spain. The demo case aims to establish sensor-based and image-based requirements, procedures and examples for generating a realistic virtual replica of the physical bridges. The twins have deemed living assets that can be updated during operation. The paper depicts actions and deployments undertaken during routine static load tests. The efforts related to sensoring, simulation, modelling, assessment and validation can be wrapped up systematically for further use during the regular operation of the asset.
