Advanced modelling of concrete bridges

The combination of non-linear finite element analysis with structural monitoring can considerably improve the prognosis of bridge behaviour, deterioration, and damage. Recently, a digital twin concept is utilized in which a digital replica of a real structure is developed. Based on the data obtained from the monitoring system installed on the Wonka bridge, Czech Republic, a computational model was calibrated. Then, advanced deterioration models accounting for chloride- induced reinforcement corrosion were applied to assess the long-term development of the structure’s load-bearing capacity. It is shown that the proposed integrated system can be used as a tool for the ageing management of concrete structures ensuring their long-term safe operation.
