This webinar will have a series of talks on Modeling and assessment of the impact of a fire on the Normandy and Tancarville bridges; Magnetic flux leakage inspection for structural defect detection in bridge cables; and Corrosion monitoring in prestressing ducts using RFID technology.
The 2025 Cable Conference, co-organized by the AFGC, Cerema, and Gustave Eiffel University, was successfully held in Nantes on 2025 April 1 and 2. This event provided an opportunity to take a look back at 10 years of technical and scientific progress in the diagnosis and repair of cable-stayed bridges, suspension bridges, and cable-supported bridges, as well as in the specific issues related to prestressing cables. The event welcomed approximately 180 French-speaking participants and 44 presentations (from France, Belgium, Switzerland, and Canada) representing diverse and complementary backgrounds (project owners, engineering and inspection consultant, construction companies, academics, and technical centers). This webinar aims to share with the international community the key advancements presented during the conference. It features 4 selected presentations from the event’s technical communications that explores cutting-edge techniques for inspecting, diagnosing, and monitoring cables in civil structures (stay cables, prestressing tendons, suspension systems, etc.).
Webinar structure:
14h-14h05: introduction of the webinar
14h05-14h20: Etienne Combescure : Modeling and assessment of the impact of a fire on the Normandy and Tancarville bridges
14h20-14h35: Bastien Vaurigaud : Magnetic flux leakage inspection for structural defect detection in bridge cables
14h35-14h50: Yannick Falaise : Corrosion monitoring in prestressing ducts using RFID technology

Circular Construction in Steel Structures: The Key Role of Connections
When: 27 November 2026, 14:00 - 15:30 hrs CET
Register (Free) online: Click here for registration and further information.
After registering, you will receive a confirmation email containing information about joining the webinar.
Speakers: Luis Simoes da Silva; Filip Ljubinković; Kristo Mela; Tiago Alves; Alejandro Bernabeu. Moderator: Dolores Pulido, Spanish NG Chair.
Steel structures offer a unique advantage for circular construction due to their durability, adaptability, and high potential for reuse and recyclability. However, the practical implementation of reuse strategies presents several challenges, including limited availability of reusable elements, the carbon footprint associated with deconstruction processes, the lack of standardized design rules for reuse, and broader economic and industrial constraints.
Connections play a fundamental role in enabling circularity in steel structures. They are key to facilitating disassembly, adaptability, and reuse, while also representing a significant share of the overall structural cost and complexity.
Building on the experience gained within the European Union-funded CONNECT4C project, this webinar will explore the context and potential of circular construction in steel structures. It will address the key requirements that such systems must satisfy, the challenges associated with their development at the system, component, and connection levels, and present the CONNECT4C project, focused on the development of high-strength, demountable, reusable, and adaptable steel connections.
Speakers: Luis Simoes da Silva, Portugal, University of Coimbra; Filip Ljubinković, University of Coimbra; Kristo Mela, Tampere University, Finland; Tiago Alves, Adao da Fonseca Engenheiros Consultores, Portugal; Alejandro Bernabeu, Bernabeu Ingenieros, Polytechnic University of Madrid, Spain.
Moderator: Dolores Pulido, Spanish National Group Chair.

Speakers: Dr. Michal Venglár; Poland Moderator: Dr. Paweł Hawryszków.
NOTE: This Webinar is being organised by the eLearning Board and the Polish National Group of IABSE.
Pedestrian bridges are one of the fascinating types of structures – this comes from design expe-riments on architectural forms, the search for new structural solutions, and creativity in the engineering process. New materials, as well as FEM and BIM software, allow designers to sha-pe structures in unique ways. On the other hand, lightweight decks combined with complicated design solutions may result in the dynamic problems. Significant failures occurred on some pe-destrian bridges in the past and still design mistakes can be met. The first part of the IABSE TG 1.15 webinar (presented by Paweł Hawryszków) will focus on design aspects, formal regu-lations, a review of guidelines and examples of footbridges, introducing this important engineering.
1. PhD Eng. Paweł Hawryszków, Poland, Assistant Professor, Researcher at the Wrocław University of Science and Technology (WUST), Poland. His main scientific activity is focused on dynamics of footbridges and bridge structures (DYN), cable-stayed bridges, bridge monitoring (SHM), Building Information Modelling (BIM) and advan-ced numerical analyses (FEM).
2. Doc. Ing. Michal Venglár, PhD., Slovakia, associate professor at FCE of Slovak University of Technology (STU) in Bratislava He is Deputy Head of Structural Mechanics at STU Bratislava and an IABMAS committee member specializing in bridge load testing and structural health monitoring.
