Circularity in Civil Engineering

The Engineering and Construction (E&C) industry is the world's largest raw materials consumer, responsible for 36% of final energy use and 39% of energy and process-related carbon dioxide emissions in 2018. Keeping the current "design-construction-operation-demolition" linear life cycle is not environmentally sustainable and not financially feasible.

​

Dr. Cao has joined the Department of Engineering Structures, Faculty of Civil Engineering and Geosciences, TU Delft. She will lead in developing the fundamental understanding of circularity in the design, construction, operation, maintenance and repair cycle of civil infrastructure.

Cyber Civil Infrastructure

Data Interpretation for Infrastructure Systems Diagnosis and Prognosis

The evolution, miniaturization and cost reductions in sensors, data acquisition systems and digital computing hardware, offer new opportunities in the condition assessment of existing infrastructure systems. The increased accuracy and data volume also raises more complex scenarios yet more challenges in data integration, data selection and system identification methodologies. 

​

Dr. Cao has worked on this research line during her Ph.D. research. The contributions include: 

  • Data Integration: Enhancing static-load-test identification of bridge using dynamic data

  • Data Selection: Time-series data interpretation for "Wheel-flat identification"

  • Vibration serviceability assessment for pedestrian bridges 

  • Smart city operation for toll highways using updated bridge loading capacity
