Teaching

In my teaching, I try to contribute to the engineering education of our students. In concrete terms, this means that I want to train engineers who, thanks to their profound scientific knowledge, are able to solve challenging engineering problems in practice. I think metal construction is particularly well suited to this: due to our lightweight construction and the outstanding properties of steel and aluminum compared to other building materials, we are able to create uniquely sophisticated buildings with clear structures - but we need a fair amount of statics, mechanics and other theory to do so. As a "real" steel constructor with 25 years of practical experience in design, fabrication and erection (see above), I also try to convey that good structural analysis is not enough for a good design, but that aspects of fabrication and erection have to be taken into account from the very beginning. If this is done, metal construction is really fun!

Fields of Research

In my research, I am interested in the effect of extreme loads, such as explosion or fire effects, on steel and composite structures. I also deal with issues of component fatigue, e.g. in bridge construction, historical bridges, lightweight construction, but also in the field of wind energy. In addition, there are important questions concerning the sustainability of buildings and bridges, which have been a focus of my research in recent years. These have also led me to address the question of the extent to which structural designs can be automated using a Genetic Algorithm. Here I see a great potential for the future, as well as in the additive manufacturing of steel and aluminum components, a relatively new research focus at my chair.

Finally, I also deal with many topics coming from engineering practice, such as shear force connections in composite construction or the influence of connection formation on the flexural torsional buckling behavior of beams, because research in engineering is not an end in itself, but should always have a more or less concrete application reference. This also includes the development of new material-efficient innovative construction methods using high-strength steels, such as bar bundle columns, plate lamella columns or weight-optimized scaffold components.

Current and ongoing research projects are listed below. In addition, there are research-related industrial projects (e.g. development of the TOPfloor Integral floor system, appraisal of the VFT-Rail construction method as well as control rod constructions of DB, etc.) which are not listed here. Also not listed are projects that were carried out within the framework of grants. More information on some of these projects can be found in the Research section. Only the research projects at TUM from 2006 onwards are listed here.
