Industrial PhD student Jens-Christian Kragh-Poulsen will spend much of the next three years in the company of 20 concrete beams in a test hall at the Technical University of Denmark (DTU). The purpose is to learn more about the strength of arch-shaped concrete structures, which are used in foundations for wind turbines.
There are loads of norms and standards on how to design wind turbine foundations, caissons, tunnels etc. However, when it comes to arch-shaped concrete structures, those norms and standards may not always provide a fair picture.
"Literature is full of tests involving straight construction members, but there is close to no data on arch-shaped construction members that are subjected to stress to determine their breaking point. We need that information in order to optimise the end result and the consultancy we offer to our customers," says Kragh-Poulsen.
He has delved into the research project with financial support from COWIfonden and in cooperation with COWI, the Technical University of Denmark (DTU) and Aarhus University.
This new knowledge will allow us to optimise concrete structures, and thereby minimise resource consumption and maximise the life of new and existing structures
