The infrastructures covered in “WP5. Rail and Road Infrastructure” are characterized by a variable traffic load. They bring together supervisors with expertise in vehicle-infrastructure interaction (Prof. OBrien (UCD) and Dr. Parry (UNOTT)), traffic load modelling (Prof. Casas (UPC) and Prof. OBrien (UCD)), uncertainty modelling (Dr. Yalamas (Phimeca)), reliability analysis (Luis Neves, Dr. Rementye-Prescott and Prof. John Andrews (UNOTT), Prof. Franck Schoefs (l’Université de Nantes), field measurements (Prof. Laefer (UCD)) and Structural Health Monitoring of bridges (Prof. Brownjohn (FSDL) and Prof. Casas (UPC)). Individual Research Projects are justified and expanded further in descriptions ESR7 to ESR14 which can be grouped in two categories:
- Bridges: Uncertainty in bridge safety is addressed via cost efficient structural performance monitoring methods using rotation measurements (ESR7), probabilistic modelling of bridge damage based on damage indicators (ESR8), railway bridge condition monitoring and fault diagnostics (ESR9), assessment based on measured vibration level (ESR10), use of distributed optical fiber sensing for SHM of bridges and large scale structures (ESR11), and the use of an instrumented vehicle (ESR12).
- Road infrastructure: Uncertainty in pavement safety is addressed via the use of production vehicle sensors for road pavement performance investigation (ESR13) and the use of unmanned aerial vehicles for regularised, automated road infrastructure inspection (ESR14).
