Winter excursion 2024

In January, the metal construction students of the Technical University of Munich went on excursion!
In winter, the first day always deals with the topics of lightweight construction, aluminum and aluminum products for facades. We started at the Zeppelin Museum in Friedrichshafen. A great museum and the perfect start to the topic of lightweight construction. A visit is highly recommended for all ages!
Afterwards we visited the aluminum hot rolling mill and the extrusion press with the largest extrusion press in Europe (100 MN) at Constellium in Singen. Andreas Fellhauer and his colleagues gave us, as always, super information and guided us!
Later, Frank Ritter, one of our alumni, and his colleagues from 3A Composites gave us a lot of information about Alucobond and similar products for façade construction, including a demonstration of processing.
On the second day we were at Montana AG in Villmergen. From Markus Duerr and his team we learned a lot about the production of trapezoidal profiles, sandwich elements, composite sheets like Holorib and about industrial facades. The tour through the production was also super informative! In the case of the weather group, there was then also a tour of the steel construction production. There was also a lot of welding, drilling and screwing. We were supervised here by Marc Kreissig and Sandra Schärer.

After the official end of the excursion, we could still enjoy the famous galvanized steel constructions in the alpine region, even if there is not much snow at the moment.

A huge thank you to the companies and people involved for their hospitality and great commitment!!!!

Scientific exchange with Japan in spring 2023

Finally, entry to Japan was possible again without any problems! This was a perfect opportunity to refresh our contacts with Japanese universities and to lay a good foundation for the Japanese-German Bridge Symposium (JGBS) in August.
In the course of this, Dorina Siebert spent a total of 6 weeks as a guest researcher at the Tokyo Institute of Technology with Prof. Sasaki in spring 2023. His chair has very good connections to the Japanese Railway and was therefore the perfect environment to provide valuable input and impulses for Dorina Siebert's DFG project "Method for assessing residual use and determining safe operating time intervals of older welded steel bridges".
Ms. Siebert's stay was combined with guest lectures by Dr.-Ing. Radlbeck on "Fatigue and Fracture of Metal Structures" as well as with an overview of current research at the TUM Chair of Metal Structures both with Prof. Sasaki at the Tokyo Institute of Technology and at Kyoto University with Prof. Sugiura. There was a great response from Japanese scientists and students at both universities. There was extensive discussion and exchange, and some promising contacts were made. Particularly remarkable was the response to the TUM sustainability projects, e.g. ReUse.

Finally, Dorina Siebert and Christina Radlbeck visited the Osaka Institute of Technology (OIT) together. The cooperation between OIT and Metallbau/Stahlbau TUM has lasted for several decades and the reception there was correspondingly warm. The focus of the meeting was on the upcoming JGBS and future cooperation opportunities.

Overall, the research stay and guest lectures were a great success and the German-Japanese exchange before Corona can be continued seamlessly.

In this context, analyses are conducted to determine the effects of the internal pressure and to examine the load-bearing and fatigue behavior of single-sided fillet welds. The results will contribute to the economic and sustainable dimensioning of one-sided fillet welds of tightly welded hollow boxes.

Thanks to the AiF member association DASt, which was very involved in the realization of the project, to our industrial partners and to the AiF!

Summer excursion: Bavaria in the Rhine Valley

From July 18 to 19, we had the pleasure of going on a summer bridge construction excursion with a group of 20 people. For this, we first went to the A9 Fürth-Nuremberg interchange to the Overfly bridge construction site. This "Overfly" represents a very special structure: in order to relieve the traffic junction and to bundle the northbound traffic of the A3 onto the A9, a so-called "extradosed" bridge was designed by the engineering office Klähne BUNG Ingenieure. During the visit, Mr. Marco Weber of DEGES and Mr. Georg Liebig of ARGE Donges/Implenia explained the reason for this special design: preservation of the landscape and compliance with the maximum construction height, given by the surrounding woodland. The sub-segments of the steel composite bridge are assembled on the construction site and moved to their final final position over the highway using the incremental launching method.
Afterwards, the students went to one of the oldest German settlements for a historical guided tour of Speyer. The Palatine dialect overtaxed one or the other Bavarian, but not our Professor Mensinger, who originally lived in this region. The evening was duly ended in Speyer's city center with a spritzer from the original Dubbeglas.
The next day, in search of the origin of the steel components of the Overfly bridge, we went to Mannheim to the company Donges SteelTec. Here, Mr. Scahde presented the impressive bridge and special steel construction projects of the company and then Mr. Nicolay and Mr. Schade showed the production of the segments of the bridge Overfly during a factory tour. Strengthened, happy and full of new impressions, we then started the long drive back to Munich.
We would like to thank all participants of the company Donges, the ARGE Donges/Implenia and the DEGES for this impressive experience and are looking forward to the next visit.

PhD seminar summer semester 2022

Our PhD seminar in the summer semester 2022 took place in Bolzano with 12 participants. In the course of 10 detailed presentations with subsequent discussion, current research work was presented and new research ideas were collected. The presentations dealt with galvanized frame bridges, composite columns with sheet metal sections using high strength steel, the structural stress concept in steel construction, and additive manufacturing in metal construction. Other topics included seal-welded hollow boxes, shape and fabrication optimization of welded-on plates, hot-dip galvanized composite beams and the load-bearing behavior of headed bolt studs in profiled plates with high webs under fire loading. Presentations were also given on high-strength tubes in scaffolding and the assessment of the fatigue safety of riveted and welded railroad bridges.

 

Major Civil Engineering Excursion Istanbul 2022

The traditionally annual Major Civil Engineering Excursion 2022 was allowed to be organized by the Chair of Metal Structures. Due to the COVID19 pandemic, it had not been able to take place for two years, which is why the efforts to create a memorable excursion were particularly intensive. 40 students were able to register to participate due to intensive support from industry. Prof. Dr.-Ing. Martin Mensinger and the scientific staff Johannes Diller M.Sc., Drilon Gubetini M. Sc., Rudolf Röß M. Sc. and Kurt Tutzer M. Sc. were responsible for the organization of the program. In order to offer the prospective civil engineers a small compensation for the online teaching without social interactions and without excursions to exciting buildings, Turkey was chosen as destination, where the suspension bridge with the largest main span in the world was recently built. Among other things, the participants were allowed to marvel at the Yavuz Sultan Selim Bridge, designed as a suspension and cable-stayed bridge at the same time, with a main span of 1408 m, both from the inside of the superstructure and from the middle span on the superstructure.

The 1915-Çanakkale Bridge, the suspension bridge with the largest main span in the world (2023 meters), was also visited, where the visit to the gigantic anchor block further accentuated the dimensions of the structure. Çimtaş, one of the world's largest steel construction companies based in Gemilik, invited visitors to tour the plant, where impressive technology, professional staff and a "zero accident" policy were evident as the basic building blocks of the company's success. At the İSKİ Ömerli Water Treatment Plant and the Pasaköy Advanced Biological Wastewater Treatment Plant, drinking water treatment and wastewater treatment in a mega-city like Istanbul were experienced live and explained through interesting lectures. To make sure that the cultural program and getting to know each other were not neglected, a visit to the Galata Tower, the Sultan Ahmed Mosque and the Hagia Sophia followed by a joint dinner were not to be missed. For the unforgettable excursion we would like to thank all people involved and the organizers as well as the sponsors from the industry who made this trip possible:

Tensegrity tower with additively manufactured aluminum nodes for the Deutsches Museum

Form finding, form optimization and additive manufacturing from design to assembly something we can do!
At the end of March, the Tensegrity tower for the bridge exhibition at the Deutsches Museum was delivered by the Chair of Metal Structures at TUM. With pressure pipes made of aluminum, the stainless steel cables and the shape-optimized, additively manufactured aluminum nodes, the construction weighs just 150kg.
Under the direction of Florian Oberhaidinger, an extraordinary project was created at the Chair of Metal Structures over the past two years that can certainly be described as state-of-the-art for steel construction. As a specialist in additive manufacturing, Johannes Diller planned and manufactured the aluminum nodes using a Realizer SLM 250 from DMG Mori. Drilon Gubetini was responsible for the entire area of measurement technology for the tower and provided decisive support for the structural analysis.
Shape optimization by Armin Geiser at the Chair of Structural Analysis at TUM gave the nodes their final shape and enabled a material saving of 30% compared to the statically dimensioned initial model. Even if the absolute savings are small, it is nevertheless clear how much resources can be saved with such an optimization.  
We were particularly pleased with the cooperation and support of Prof. Krafft of the Munich University of Applied Sciences. In the laboratories for applied materials technology, the nodes were heat-treated and prepared for installation.
We would also like to thank all the persons and companies who supported the project. A special thanks goes to Stahlbau Hausmann for the support during the installation and for the fabrication of the base plate, the pressure pipes and the inlays. Furthermore we would like to thank Jakob Rope Systems for the production of the ropes and Rösler Oberflächentechnik for the vibratory grinding of the nodes.

Lectures summer semester 2022

The lectures at the Chair of Metal Structures in the summer semester 2022 will be held in presence.
All information on the schedule and the course materials will be made available on Moodle by the beginning of the semester.
According to the currently valid Infection Protection Measures Ordinance, as of April 3, 2022, there is no longer a 3G obligation for entering TUM premises, so that the corresponding compliance check is no longer required. The obligation to wear a mask has also been lifted, but we urgently and emphatically recommend the use of FFP2 masks on all TUM premises where the minimum distance of 1.5 meters cannot be maintained.
If you have any questions, please do not hesitate to contact us.

PhD seminar summer semester 2021

Our PhD seminar in the summer semester 2021 took place in Munich with 17 participants. In the course of 14 detailed presentations with subsequent discussion, current research work was presented and new research ideas were collected. The presentations dealt with galvanized frame bridges, bar-bundle columns with high-strength reinforcing steel, composite columns with sheet metal sections using high strength steel, longitudinally stiffened buckling fields under multiaxial loading, and additive manufacturing in metal construction. Other topics included the ultimate load increase of predominantly compression loaded hollow structures, shape and fabrication optimization on welded-on plates, hot-dip galvanized composite beams and the load-bearing behavior of headed bolt studs in profiled plates with high webs under fire loading. Presentations were also given on high-strength tubes in scaffolding, the assessment of the fatigue safety of riveted and welded railroad bridges, the development of a mobile safety system for protection against vehicle attacks, and the automated preliminary structural design of steel-concrete composite buildings.

 

Public presentation of student designs for the planned urban bike bridge Ständlerstraße - A8

In the summer semester of 2021, our master's students have worked out and visualized designs for the replacement of the Ständlerstraße - A8 cycle path bridge.

A total of nine teams designed a wide variety of bike bridge structures under the supervision of Professor Martin Mensinger of the Chair of Metal Structures. In addition to idea generation and concept development at the beginning of the project, calculation, construction and visualization were important components of the project. The students received direct practical support from five Munich civil engineering offices.

The results are attractive designs of a barrier-free pedestrian and bicycle bridge as truss, arch and cable-stayed structures. The designs are based on the planning principles of the building department and were presented on 15.07.2021 in the Audimax of the TUM and met with an enthusiastic response. If you are interested in details of the designs, please contact our secretariat.

We would like to thank the civil engineering offices BPR, Bulicek, Grassl, SSF, ZMI for their support and the students for their extraordinary commitment. We would like to thank Mr. Michael Dzeba, City Councillor, representing the Lord Mayor of the City of Munich, and Mr. Andreas Kapeller, representing the Building Department, for coming and for their cooperation.

Final presentation of student designs for the planned urban bicycle bridge Ständlerstraße - A8

Good news: On the way to CO2-neutral steel production

Steel is already the building material with by far the highest recycling rate. Well over 90% of the rolled sections used in German-speaking countries, are made of recycled material which, after use, can even be reused to make particularly high-quality products and does not have to be "thermally recycled" or buried in road construction.


Now the steel industry, together with the German government, is setting out on the road to C02-neutral steel production. The aim is to replace carbon as a reducing agent in primary steel production with climate-neutral hydrogen.

Further information on this major step in the right direction can be found here:
