    Digital twin approach for durability and reliability assessment of bridges

  • Original language description

    Digital twin is a modern concept, in which a digital replica of a real product and structure is developed, and a simulation is performed to test the product behaviour under service conditions. In the presented paper the digital twin method is used for making assessments of safety, durability and reliability of bridge structures. Although some numerical modelling is often done when an existing bridge is evaluated, it usually does not involve the simulation of real behaviour under service and environmental loads including chloride ingress, reinforcement corrosion and assessment of ultimate load carrying capacity. The digital twin concept in addition includes an important aspect of the digital twin calibration and validation using the real monitoring data. The paper presents a chemo-mechanical model covering initiation and propagation of chlorides or carbonation. This model is combined with the nonlinear modelling of cracking, bond failure and reinforcement yielding (Cervenka and Papanikolaou (2008). The paper extents the previously developed model by the authors Hájková et al. (2019), Jendele, Šmilauer and Cervenka (2014). The models were implemented in ATENA software and are validated on experimental data. The developed models can be efficiently used in large scale analysis of real engineering problems as demonstrated on applications to an existing bridge structures in Germany. The example simulation using the digital twin concept show time development of reinforcement corrosion due to chloride ingress, and their impact on the evolution of structural safety and reliability. © Proceedings of the fib Symposium 2020: Concrete Structures for Resilient Society.
