Digital Twins for Reinforced Concrete Structures

Popis výsledku v původním jazyce

Digital twin is a new approach in structural life-cycle management, when a virtual replica of a real product or structure is developed. The virtual twin is used to test the product behavior under limit state conditions. The important feature of the digital twin is the connection of the virtual model with the real-life data obtained by its monitoring. The digital twin method can be used for the assessments of safety, durability and reliability of reinforced concrete structures. The presented digital twin model consists of a finite element mechanical model coupled with a chemo-mechanical model for the assessment of chloride ingress or carbonation and propagation of the subsequent reinforcement corrosion. The model is combined with the nonlinear modelling of cracking, bond failure and reinforcement yielding for static as well as dynamic analyses. The digital twin approach is demonstrated on pilot problems of bridge structures in the Czech Republic and Germany. The latest development also extends the digital twin approach for the additive manufacturing of concrete structures, where the G-code generated by the robotic machine is directly used for the simulation of the construction process as well as for the assessment and verification of the final structural behavior under design loads as well as its long term behavior.
