The research field of Structural Dynamics combines numerical simulations, laboratory experiments and site measurements on existing structures. This also include development, and application, of new methods and techniques for numerical simulation of dynamic response. 

Safety and reliability are important factors for all application areas, and one main goal of the research is to generate data that may be used to improve the design of bridges and railways and help extend the technology to solve the challenging problems of the future.

From 12th to 13th of June, members of the Structural Dynamics group attended the 20th Nordic Seminar on Railway Technology in Gothenburg, Sweden. The conference was organized and hosted by the Chalmers University of Technology, in collaboration with the Chalmers Railway Mechanics (CHARMEC) group.

Professor Anders Rønnquist and PhD candidate Stefano Derosa presented the group work regarding the dynamic of pantograph/catenary interaction and the Hell Bridge test arena, giving rise to interesting conversations and debates with the other participants from all the Nordic countries.

On Friday 8th of June, the first biannual group seminar of 2018 was held at the Department of Structural Engineering at NTNU. According to the tradition of the group seminars, selected PhD students gave 45-minutes-long presentations on ongoing research:

  • A brief introduction of our study on pantograph-catenary system dynamics  and application of non-contact detection (F. Duan/SWJU-NTNU)
  • MatLab toolbox for Machine Learning (Y. Xu/NTNU)
  • Getting started with Python in science and engineering (G.T. Frøseth/NTNU)
  • Working with the Python API in Abaqus (Ø.W. Petersen/NTNU)
  • Hard parametric life (M. Luczkowski/NTNU)

Following the interesting talk during the seminar, a dinner at Sabrura concluded the event.

On Friday 6th of April, Aksel Fenerci defended his PhD thesis entitled “Full-scale investigation of the effects of wind turbulence characteristics on dynamic behavior of long-span cable-supported bridges in complex terrain”. Previous to the defense he held the trial lecture with the assigned topic of: “Application of wind and turbulence data in relation to atmospheric meso and microscale models in the design of long-span bridges”

Opponents were Professor Giovanni Solari from University of Genoa (Italy) and Associate Professor John Owen from University of Nottingham (UK). Main supervisor during the PhD was Associate professor Ole Øiseth.

The Structural Dynamic group is pleased that Aksel will continue as Post Doctor at the Structural Engineering Department here at NTNU.

13th of February, Bartosz Siedziako defended his PhD thesis entitled "Modelling of the self-excited forces for bridge decks subjected to random motions: an experimental study". The trial lecture had the following prescribed subject: "Cable vibrations in cable supported bridges". 

A video of the wind tunnel rig made by Bartek for his PhD work can be found on YouTube. 

Opponents were Professor Alberto Zasso from Politecnico di Milano (Italy) and Dr.ing. Ketil Aas-Jakobsen from Aas-Jakobsen AS. Associate Professor Ole Øiseth was the main supervisor.

The group wish Bartek the best of luck on his new job as a structural engineer at Norconsult in Trondheim.
