Study of the materials of the Castro viaducts. Collapse of two spans in 2022.


Piedrafita do Cebreiro, Spain
Key data:

Viaduct built in 1999 that, in June 2022, while it was being reinforced, suffered the collapse of two of its spans. The General Directorate of Roads asked INTEMAC to document the resistant characteristics of its materials.


Damage inspection, Study of project documentation, performance of non-destructive and semi-destructive tests (tensile strength, deformation modulus, weldability, etc.) of structural elements and samples obtained from them. Analysis of test results. Finite element modelling. Verification of stresses and safety and durability conditions. Proposed repair/reinforcement for future use.
