Digital Twin for Modelling Structural Durability

Popis výsledku v původním jazyce

The reinforcement corrosion due to chloride ingress is an important deterioration mechanism, which may compromise the service life of reinforced concrete structures. This study presents a bridge monitoring system coupled with an advanced chemo-mechanical computational method for an estimation of chloride ingress and reinforcement corrosion. Based on-site measurements, a digital replica of the bridge is calibrated and by applying the degradation models, the reduction of structural performance is simulated. Apart from the structural analysis, the data from the monitoring system can be used to deduce information about the daily traffic crossing the bridge. Pilot applications of the proposed coupled framework are shown for two concrete bridges, where a 150-years-long chloride attack was assumed for the assessment of the long-term structural performance. The structural resistance was evaluated by the methods based on fib MC 2010, namely the estimation of a coefficient of variation method (ECOV) and partial factor method (PFM).
