KTH Royal Institute of Technology

KTH Royal Institute of Technology in Stockholm has grown to become one of Europe’s leading technical and engineering universities, as well as a key centre of intellectual talent and innovation. We are Sweden’s largest technical research and learning institution and home to students, researchers and faculty from around the world. Our research and education covers a wide area including natural sciences and all branches of engineering, as well as architecture, industrial management, urban planning, history and philosophy.

Project description

Third-cycle subject: Civil and Architectural Engineering, specialisation in Structural Engineering and Bridges.

We are looking for two PhD-students:
One PhD-student to study vibrations in footbridges (Project 1) and one PhD-student to study vibrations in railway bridges (Project 2).

Project 1:

This project focuses on the dynamic performance of footbridges. The aim is to study the effect of runners on footbridges, both with respect to high vibration amplitudes and with respect to the perceived comfort for people standing on the bridge. Experimental investigations and computer simulations considering the effects from human-bridge interaction will be performed with the aim of improving the current design methodology. More specifically, the project will involve the following:

  • Laboratory tests on an instrumented treadmill for characterisation of running loads.
  • Development of numerical models to cover the running load case and several interaction effects.
  • Field tests to verify the numerical models against measured data.
  • Investigate the possibility to use fluid viscous dampers for mitigation of excessive vibrations of footbridges.

Project 2:

This project focuses on the dynamic performance of railway bridges which are often subjected to significant dynamic loading due to passing trains. The current limits for the dynamic design criteria in the European bridge design code (most importantly the limit for the bridge deck vertical acceleration) are based on a simplified approach for safety factors. A more realistic design limits will require a better understanding of the coupled train-track-bridge system.

The aim of the project is to propose a new design methodology for dynamic analyses of railway bridges for high-speed trains. A probabilistic framework will be developed to propose a more realistic safety format. This work will involve a large parametric study considering train-track-bridge interaction where uncertainties in assumptions are dealt with using a probabilistic approach.
