PhD Position, Department of Structural Engineering
About the position
We have a vacancy for a PhD Candidate at the Department of Structural Engineering.
NTNU is working with the Norwegian Railway Directorate and Bane NOR on challenging engineering projects for future railway systems. This work also considers our critical infrastructure such as existing railway bridges. Using numerical simulations and field measurements, we can improve our understanding and predictions methods of remaining life of railway bridges. This can also help to improve the design procedures and railway traffic loads.
A growing problem with infrastructure in the world today is aging and deterioration. Bridges are essential components of the infrastructure and these structures are reaching the technical life. The infrastructure owners need to ensure that components making up their infrastructure has a satisfactory standard in regards to serviceability and safety. In doing this they rely on inspections and service life estimations to ensure that the bridges have satisfactory standard. Current inspection regimes are not robust enough to detect serious faults reliably under general conditions, typically cracks in the material due to fatigue or overloading. In the research for new inspection methods we work with different types of sensor technology and analysis techniques such as system identification and machine learning to reliably detecting damaged components.
The Structural Dynamics Group has had a great development over the last 10 years with a specific focused on dynamic simulations, field measurements, system identification, load modelling, remaining life estimation, bridge aerodynamics in field and by wind tunnel experiments. The Structural Dynamics Group works with all types of structural dynamics but has particularly experience from critical infrastructure of road and rail. The group has had a great focus on field measurements used for verification of load and response models. www.ntnu.edu/kt/dynamics
The position reports to supervisor professor Anders Rønnquist.
Main duties and responsibilities
The remaining service life of existing railway bridges must be determined to ensure safe and reliable operation of the bridges and allow efficient distribution of limited funds for maintenance and renewal of the railway infrastructure. Material fatigue is one of several damage mechanisms in steel bridges that are determined by traffic loads at the bridge site. To improve service life estimates of steel railway bridges it is therefore necessary to use enhanced traffic load models.
- The PhD candidate is expected to perform the following task during the study:
- Establish finite element models of existing bridges for global and local response analysis.
- Estimate stress response in railway bridges by numerical simulation of train passages.
- Conduct field measurements on existing bridges.
- Conduct service life estimation of critical bridge details.
- Perform load measurements of regular traffic on the railway infrastructure.
- Evaluate and enhance existing load models for service life estimation of steel bridges.
- Consider use of machine learning and other statistical methods for damage detection.
- Participate in national and international scientific conferences and publish results academic journals.
