Full-scale monitoring
The Structural Mechanics group possesses extensive expertise in the comprehensive monitoring of civil infrastructure, employing a diverse array of sensor technologies. Their focus encompasses bridges, buildings, and railway infrastructure. Going beyond simple data collection, the group's proficiency lies in the meticulous analysis of this data, crucial for assessing the behavior across these infrastructural elements.
The data-driven approach is instrumental in aiding critical decision-making processes in asset management, empowering stakeholders with comprehensive information for design feedback, safety enhancement, and optimal rehabilitation initiatives.

Structural monitoring acquires vital information on the structures' behavior under live operational conditions but also generates crucial inputs for service life estimation, facilitating a deeper understanding of the assets' durability and longevity. Moreover, in-situ data serves as a foundational element for refining finite element models, enabling precise calibration and validation of digital models used in structural analysis.
Additionally, this data is leveraged for the development and implementation of load estimation and virtual sensing techniques, enabling accurate monitoring and predictive analysis even in scenarios where direct measurements are not feasible.
The group's multifaceted approach to monitoring extends across various domains, exemplified by their work across different infrastructure types:
- Tall timber buildings – Calibration of numerical models for the exploration of novel eco-material applications
- Steel bridges – Detection of damages and continuous fatigue monitoring for improved safety
- Long-span suspension bridges – Understanding wind-induced responses and modelling of environmental loads
- Floating bridges –Wave load effects and responses for unconventional structures
- Railway infrastructure – Assessment of track-train-pantograph interactions and fault detection
- Pedestrian bridges – Documentation of dynamic responses induced by human loading
