Simulation and monitoring of the behaviour of floating bridges
To be able to develop present floating bridge technology, it is crucial to have detailed knowledge about the performance of existing floating bridges. An extensive measurement program on the Bergsøysund Bridge is therefore a part of this research project. The measurement system includes recording of the environmental excitation and the response of the bridge. The Bergsøysund Bridge is one of two end-supported floating bridges in the world, and is considered a very interesting case study. By comparing the measurements to numerical predictions based on state of the art methodology, the accuracy and uncertainties of the methods will be studied. The overall objective is to contribute to floating bridge technology, such that an economic and reliable design of future strait crossings can be achieved.
The tasks of my project should help answer the following research questions:
- How does a floating bridge behave, and what environmental parameters affect the behavior?
- How well do the current prediction methods estimate this behaviour?
- How big are the uncertainties?
- What is the cause of the uncertainties?
