EVACES 2023 in Milano – Focus: Monitoring Systems

"Welcome to Milano" was the welcome message for this year's EVACES conference, which focuses on experimental vibration analysis of engineering structures. The tenth edition took place last week was hosted by the Milan-based Politecnico. The focus this time was on monitoring systems, that is, with the sensory monitoring, whether short-term or permanent, of critical civil engineering structures.

The conference is intended as a platform for exchange between science and industry, where the latest research results, developments and applications can be presented and discussed. The exchange on all important aspects of vibration-based monitoring and testing enables ever better condition analyses of civil engineering structures.

We were represented with two expert contributions. Georgios Balaskas presented "Experimental system identification and damage detection in steel-concrete composite frames subjected to monotonic and cyclic lateral loads" on earthquake loaded industrial plants and their monitoring.

Thorben Geers has explained the comparability of bridge monitoring systems for different types of structures under the title "Data-based condition and prognosis statements of bridge structures via standardized monitoring systems". The aim is to compare the condition of different structures for optimized maintenance under permanent traffic load.

We thank you for the excellent organization and are already looking forward to the next EVACES 2025.

Visit to the construction site of a boarding house in modular timber construction

A few weeks ago, the Institute was allowed to visit the construction site of a new boarding house in modular timber construction near Düren. In contrast to the usual modular construction with steel frames, this building is completely made of wooden panels. The construction of the building is the result of our Hybrid-Module research project. In the project, we developed optimised room cells together with the company BOLLE System- und Modulbau GmbH.
Raphael Bruns, the managing director of the company BOLLE, showed us around the construction site and explained the special features of the building. He pointed out the elaborate preliminary planning and the skilful mastering of various challenges. All in all, the tour of the construction site of the new boarding house was a successful insight into the innovations and developments in the field of modular and sustainable construction. Many thanks to Raphael Bruns and BOLLE for this opportunity!

Doctoral Examination of Rafaela Don

Recently, our college Rafaela Don defended her dissertation in Romania. Her thesis, titled "Seismic performance of multi-storey frames with slim-floor beam-to-column joints," investigated the possibility of integrating slim-floor beam-to-column connections into steel and steel-concrete composite frame systems designed for medium and high seismicity. Currently, the application of slim floors is limited due to the assumption of articulated bearing and lack of rules in the current Eurocodes. Rafaela developed a design procedure based on experimental studies of the connections as well as advanced numerical simulations, with which the slim-floor beam-column connections can be used for structures in seismic regions.

We congratulate very much to the passed examination!

Life-Cycle Conference IALCCE in Milan

Last week, two of us were at IALCCE 2023 in Milan. The conference at the Politecnico Milano is all about "Life-Cycle Civil Engineering", i.e. circular construction with a view to the use of sustainable materials and constructions.

In this context, the reuse of building components or entire structures also represents a sustainable alternative to recycling. In this context, Kevin Janczyk presented his paper "Numerical de-termination of the wrinkling stress of steel polyurethane sandwich panels for reuse scenarios" on the reuse of facade elements made of sandwich panels.

Felix Eyben presented the paper "On the development of regulations for the increased reuse of steel structures", which deals with the necessary steps to create normative regulations for the reuse of steel structures.

In addition to many exciting presentations, it was also possible to establish contacts and promote scientific exchange. Of course, a typical Italian aperitif was also included.

All conference papers are freely accessible under this link.

  New Timber Construction Project HELEPOLIS Copyright: © STB

New Timber Construction Project HELEPOLIS

Some time ago the new timber construction project "HELEPOLIS" was started at the institute. The timber panel construction method discussed here is a widely used timber construction method with a high degree of prefabrication, short construction times and extremely low resource consumption. Currently, timber panel construction is the preferred choice for timber buildings with few floors. The project aims to make this construction method more attractive for multi-storey buildings as well.

The aim of the research project is to develop a calculation approach for the load-bearing consideration of (fire protection) claddings. For this purpose, the load-bearing behaviour of timber panel walls with cladding is to be investigated experimentally and numerically. Based on the results, a calculation method is to be developed that can reliably represent the load-bearing behaviour of timber panel walls with cladding.

Research partners are WALTER REIF Ingenieurgesellschaft mbH and ADAMS Holzbau - Fertigbau GmbH. The project will run until June 2025 and is fundet by FNR - Förderprogramm Nachwachsende Rohstoffe des BMEL.

  CEN/TS 19100 Copyright: © stb

The new CEN/TS 19100: Design of glass structures


After 10 years of hard work, another step has been taken on the way to European glass structure standardisation!
With the publication of the three parts of CEN/TS 19100, it becomes clear in which direction structural glass engineering in Europe will develop.
As a forerunner to "Eurocode 10 - Design of glass structures", which will be published for the first time in 2027, CEN/TS 19100 already shows the most important topics of structural glass engineering and the current state of research and standardisation.
Our Professor Markus Feldmann (Chairman of the Committee TC 250/SC 11 Structural Glass) took this publication as an opportunity to write an overview and summary of the work steps and contents of the Technical Specification.
The publication has been published in one of the leading European journals in glass construction ("Glass Structures and Engineering") and can be accessed under the following link.

After all the work and fruitful discussions, we must not forget to thank all those involved:
Many thanks for your energetic work in the Project Team as well as in the Committee!

Excursion to the Rhine bridge in Leverkusen

27th of October 2022

Today a post to one of our exciting excursions of the last year...

At the end of October, interested employees and students went to the well-known construction site of the Rhine bridge in Leverkusen. There we were first given a tour of the old bridge to see for ourselves the damage that has occurred over time and especially due to the increase in traffic. The engineer in charge, Mr. Jungmann from the Autobahn GmbH, also told us one or two anecdotes about the process from the idea to renovate the bridge, to the closure for heavy traffic, to the realisation that a new bridge is necessary. Afterwards, the construction site of the new bridge was visited. It will be a cable-stayed bridge with two hollow boxes in steel construction. In particular, the challenges that arose during the construction of the new bridge were presented to us.

PS: We recommend the video of the "Sendung mit der Maus" about the Leverkusen motorway bridge to get an overview of the project:

  Metal welding Copyright: © stb

Welding of headed studs in composite constructions

In composite constructions, concrete and steel profiles are combined in order to make optimal use of the different materials. This is used particularly in bridge construction and multi-storey car parks. But how exactly is the “composite action” achieved in these types of constructions? The best way to find out is to ask the expert. The expert in this case is Dipl.-Ing. SFI Rainer Trillmich (IWE) from Bolte GmbH. Mr Trillmich visited us in our lab at the end of last year to weld headed studs needed for the bonding of steel- and concrete cross-sections onto our test beams. And he turned it into an impromptu lecture on stud welding! What are the characteristics of a proper weld, which edge distances should be met and how are headed studs tested? Additionally, exciting illustrative material was also captured for the Institute’s lectures. The video can be found on our LinkedIn channel. But be careful: the welding process, which only takes roughly one second, produces a bright flash. So put on your sunglasses and be amazed!

Timber construction excursion

25th of October 2021

On 25.10.2022, the Institute of Steel Construction went on a day excursion with interested students of timber construction. The first stop of the excursion was the timber construction company Derix in Niederkrüchten. During a guided tour of the production hall, we were shown the fully automated production processes of glue laminated timber. We got an insight into the production of cross laminated timber (X-LAM) and glulam (BSH).

The trussed arches of the airship hangar, which we visited later, were shown to us here in production. After the guided tour through the factory hall, Derix presented further projects in Norway, the Netherlands and Germany.

Arriving at the airfield in Mülheim, we were welcomed by the planning team of the new airship hangar. Here, the team showed us in presentations their approach to planning the new home of "Theo", WDL's airship. The various stakeholders, such as the project controller IB Römling, the architects Gronau and a structural engineer from the company Ripkens-Wiesenkämper engineers told us about the challenges of planning the closing mechanism of the gantry in cooperation with mechanical engineers and calculating the wind load in a virtual simulation. The supporting structure is characterized by an impressive span, resp. spatial volume, of 92 x 26 x 42 m³ and K-nodes with dowels made of beech wood. This supporting structure is mainly stiffened by cross laminated timber panels.

After the presentation, the visit of the airship and the construction site was exciting and impressive. At the same time to conclude the day, we were able to talk to the structural engineer and other stakeholders. By now, the airship "Theo" has been moved into the hangar, as you can see here in this post.

Up high! Monitoring wind turbinesay

The team around Prof. Feldmann and Prof. Kemper is making a modest contribution to the implementation of the energy transition. They are investigating in more detail the extent to which the tower construction of wind turbines is stimulated to vibrate by the operation of the turbine and the natural wind. The aim of the investigations is, among other things, to keep turbines in operation longer in the future or to reduce the amount of steel required.

To this end, the team from RWTH Aachen University is installing elaborate measuring technology in the first step in order to precisely record the movements of an exemplary tower for several months.

Of course, the installations are carried out personally by the research team. In addition to a head for heights, medical fitness tests and height rescue training (also carried out by RWTH-Aachen), there is one thing above all: lots of fun!

We would also like to thank BMR energy solutions GmbH for their kind support.

Building physics and static investigations on the hybrid module at Bolle

08th to 09th July 2022

As part of the "Hybridmodul" ZIM-project, the workgroups Sustainable Metal Building Envelopes and Timber Structures visited Bolle Modul und Systembau GmbH ( in Telgte on 7 and 8 July. The aim was to examine a modular building prototype made of wood from the point of view of building physics and statics. On the first day, the air tightness was determined with the help of a blower door test and then the sound insulation properties of the prototype were examined. The airborne sound insulation of the exterior walls, the impact sound insulation of the ceiling and the reverberation time of the interior were determined. On the second day, thermographic images were taken to detect thermal bridges.

In addition, investigations were carried out on the supporting structure of the module prototype. During these investigations, first the deflection of the module and then the dynamic stiffness were determined with the help of accelerometers.

We are pleased with these first promising test results, which show great potential for this innovative and sustainable construction method.

Excursion to X-Wood in Kall

10th of June 2022

The excursion to the Eifel region took place within the framework of the course "Timber Construction in Practice" supervised by Burkhard Walter. The founder of X-Wood, Michael Schumacher, gave insights into the founding phase and the development of the company. Mr. Walter and Mr. Schumacher gave a tour of the Hilger Holz timber hall in Kall, which was designed by Ingenieurbüro Walter in 2018 and erected by X-Wood. The cross-sections and dimensions of the connections are adapted to the load, so that an economical and resource-saving design is ensured by high utilization rates. Large spans can be realized through high slender glue laminated beams. The special feature of the X-Wood construction method is the high degree of prefabrication, which requires only short assembly times on the construction site.

Mr. Schumacher explained the work steps in production on the basis of the company's own production plant with modern joinery system, which was put into operation in 2021. At a concluding informal get-together, the students were able to engage in professional discussions with the experts Burkhard Walter, Michael Schumacher and Benno Hoffmeister and establish initial contacts with the practical world.

Center Building and Infrastructure Engineering founded on the RWTH Aachen Campus

19th June 2019

The Center Building and Infrastructure Engineering (CBI), a center in the Cluster Bauen on the RWTH Aachen Campus, has been successfully launched. The center was founded by the four institutes of construction research, solid construction, steel construction and road engineering of RWTH Aachen University with the aim of setting new trends and making existing innovations and technologies in construction more efficient and faster to implement.
The focus of the CBI's work is on the research, development and market introduction of innovative, tailor-made, application-optimised materials, construction methods, processes or concepts, also in connection with the digitalisation of structural engineering and transport infrastructure construction. In addition, the CBI focuses on simplifying the transition to regulations and approvals so that innovations can be implemented more quickly. This is necessary because complex standardization and approval processes inhibit the transfer from the laboratory to the construction site. "Innovations and technology transfer are to be implemented faster and more efficiently in 6-12-month consortium projects. This can only be achieved with strong partners at our side," says Dr.-Ing. Carl Richter, Managing Director of CBI. The first meaningful results were presented at the 1st Center Meeting on 18 and 19 June.

Most of the network partners come from the field of lightweight metal construction and cover the entire value chain from planning, production and processing of semi-finished products to assembly and refurbishment. Another company complements the network with expertise in the field of organic solar films. This bundling of competencies enables a holistic view of the life cycle in lightweight metal construction to be achieved. The focus is on increasing energy efficiency and conserving resources while maintaining a high level of functionality. The network has been managed by Jöckel Innovation Consulting GmbH since the beginning and will be continued beyond the funding period.

Sieglos Stahlbau: Renewed Runner Up

16th May 2019

RWTH Faculty 3’s Institutes battled it out on the Könishügel’s football pitch as they do every year. 13 teams competed to determine the deserving title holders of this year’s Bau-WM. All of the notorious crowd pullers were present, from A for aerated concrete to ϕ for “.ϕc-Geotechnik”. “Sieglos Stahlbau” represented the Institute of Steel Construction well, in not doing justice to their name once again. Renewed athletic masterstrokes were called for after last year’s final. As always, the team had initial difficulties finding their way into the tournament and seemed to be strapped to a railway track after their 0-0 against “Lokomotive VIA” in the first group match. Sieglos Stahlbau put the experience of their diverse team to use in their second match against “FS Bunkerkick”. The combined force of the Institute’s senior engineers, without whom the tournament just wouldn’t be the same, the team rung in a 2-0. Another 2-0 against the building technicians, the E-3DOs, who weren’t able to keep their cool for over 12 minutes, secured Sieglos Stahlbau’s first place spot in Group A and fuelled hope for a tense quarter final. There, the Steel Construction Institute’s athletes met the ever-surprising “Road-Runners” from the ISAC. Unlike their cartoon counterpart, Wile E. Coyote, Sieglos Stahlbau caught up to the Road-Runners and dropped a 2-0 anvil on them. In the arguably most thrilling match of the day, against “Blutgrätsche IBAC” Sieglos Stahlbau rolled out a close 1-0 win. Ultimately, Sieglos Stahlbau re-played last year’s final against the reigning champions and the tournament’s organisers “Kupferbolzer 05”. Copper turned to gold as the Kupferbolzer 05 beat Sieglos Stahlbau 3-1 after the latter put all their eggs in one basket for a final equalizing goal, only to be taken advantage of in a ruthless counter goal. Thus, Sieglos Stahlbau settled for being the best second place team once again.

All in all, the sporting achievements of each participant couldn’t be praised enough. Acquaintances in different Institutes were cultivated, drinks and barbeque were savoured, all on a fun-filled sunny day. A special thanks goes out to the event organisers and to all players. In prospect of next year’s tournament, the athletic management of Sieglos Stahlbau declares: “Watch out Kupferbolzer!”.

Second place is a miracle for "Sieglos Stahlbau"

July 13th, 2018

Our football team "Sieglos Stahlbau" has suffered a defeat in the World Cup final against Kuperbolzer 05. And still feel like a winner. The team is not called "Die Mannschaft" - but it is one.
After losing to Kupferbolzer 05 at this year's 17th "Bauingenieurweltmeisterschaft", the Institute of Steel Construction is proud of the best performance since winning the "Bauingenieurweltmeisterschaft" in 2012, and after a mixed preliminary round with a win and a defeat, the team entered the quarter-finals. There, after an exciting 0:0, they defeated the Road Runers in a seven-metre shoot-out. The semi-final could hardly be surpassed in tension. After a 2-0 lead, the opponent of Lokomotive VIA was allowed to come to a 2.2 equaliser in order to prevail again in the seven-metre shoot-out. In the final, the team lost to Kuperbolzer 05 0:1.
