Infrastructure asset protection and management
Research
The deterioration of large engineering infrastructure systems (eg, bridges and ports) represents trillions of dollars in public and private domains world-wide. In practice, decisions related to the assessment of engineering structures are based on uncertain and incomplete information. Uncertainties arise due to the variability in environmental factors, extreme events (eg, bushfires and hailstorm), methods of inspection and data collection, to name a few. Despite continuous improvements in accuracy of the current deterministic models and computational tools, a solution to the problem of identification of the uncertainties of the model parameters is yet to be found. The overarching aim of our research is to develop a holistic theoretical framework to allow the assessment of performance of engineering structures using reliability analysis and artificial intelligence. Specifically, our major research areas are:
- Intelligent structural health monitoring of engineering infrastructure using unmanned vehicles and artificial intelligence
- Reliability-based life-cycle performance assessment of engineering infrastructure (eg, corrosion resistance assessment of engineering structures under marine environment, and aerodynamic performance assessment of bridges under strong wind conditions)
- Learning from nature – bioinspired engineering for engineering infrastructure protection
