repair outlook identity after time machine restore

In many countries all around the world, transportation infrastructures are facing new challenges in terms of ageing and loss of performance, from both a structural and functional perspective. Results of ambient vibration tests and operational modal analyses are described, providing an idea of dynamic test requirements, as well as their use within the framework of the digital twin model creation. Both infrastructures are multi-span pre-stressed RC bridges that were dynamically tested after the restoration and seismic upgrading works.

Issues such as the quality of instrumentation, the numerosity, and layout of sensors, and the acquisition and post-processing procedures are addressed through applications to two real bridge case studies. In particular, the role of dynamic tests performed on bridges for the development of digital twin models is addressed, paying attention to test procedures and requirements. This paper discusses the advantages of developing digital twin models for the management of infrastructures, with a focus on bridges. In this context, digital twin models of the infrastructures should have a key role to simplify and speed up the procedures for proper maintenance.

The infrastructural asset managers are required to perform scrupulous control of the health condition of the infrastructures over time and to execute the required maintenance works. Many transportation infrastructures all around the world are facing new challenges in terms of ageing and loss of performance.
