In a world where the safety of nuclear structures is more than ever a central concern, Egis stood out by winning the "Tech Solution of the Year" award at the 2nd Tech Show for Construction Trophies organised in Paris on 25 June by Le Moniteur and Cahiers techniques du bâtiment.
This award is the crowning glory for our innovative solution "Behavioural model for digital twins", specifically designed for reinforced concrete structures, on behalf of our client EDF.
The recognition of this solution underlines Egis' pioneering approach in responding to the seismic challenges highlighted by the Fukushima disaster. Working closely with leading academic institutions such as École Centrale de Nantes, Université Gustave Eiffel and EDF R&D, our engineers and experts have developed a two-dimensional model of reinforced concrete for multi-scale analysis, thereby increasing the resilience of nuclear structures.
"The "digital twins" we have developed make it possible to simulate with great precision the evolution of cracks, concrete damage and the deformation of steel reinforcements," explain Miquel Huguet Aguilera and Olivier Lherminier, PhDs in nuclear civil engineering.
"This technology, validated by in-depth research, provides an accurate assessment and improved prediction of the behaviour of reinforced concrete structures in the event of an earthquake," said Silvano Erlicher, the Group's Director of Civil Engineering/Structures.
François Martin, Director of Egis' nuclear business, said: "The result of 10 years of research and development, this "made in Egis" solution contributes to the safety of nuclear structures and opens the way to wider applications for the durability of infrastructures and the extension of the life of nuclear installations. I am very proud of our team who, through their remarkable work and ingenuity, continue to position Egis at the forefront of innovation in nuclear civil engineering."
For Sébastien Laboureau, Technical Director of Uby and co-president of the jury, "this research is particularly useful for predicting the ageing of reinforced concrete structures. These predictive models make it possible to anticipate defects because they include very different elements, such as prestressed beams".
