Together with Mr. Sören Klein and Mr. Helmut Wolf from SSF Ingenieure AG in Düsseldorf, we are pleased to receive a current and innovative insight into engineering practice. We would like to invite you to the guest lecture "New developments in composite bridge construction" on Monday, January 20th, 2020 at 12:30 pm, room IC 03-606.

December 2019 – Trip of the Chair to Frankfurt
The trip of the Chair in 2019 led the team to Frankfurt this year. The Commerzbank-Arena and the unfinished conversion of the Junghof Plaza were visited, followed by a visit to the Christmas market. Frederik Gehrke provided exciting insights into the operation of the Frankfurt stadium. The companies LUPP and Werner Sobek, Frankfurt introduced us to the Junghof Plaza construction site. The substructure of the high-rise building in solid and composite construction in the inner-city area offers numerous challenges for planning and execution. The chair would like to thank you for the illustrative explanations and the hospitality.

September 2019 - The Seventh International Conference on Structural Engineering, Mechanics and Computation, Capetown, South Africa
"The Seventh International Conference on Structural Engineering, Mechanics and Computation" (SEMC2019) took place from 02.-04. September in Cape Town, South Africa. Over 400 participants from 62 different countries presented the mechanics of materials and structures, computer-oriented simulations and the latest research results. Faranak Faghihi presented her work on "Thermal coupling in hybrid fire simulation" in the "Fire Resistance, Simulations & Modeling".

July 2019 - Seminar "TEKLA-STRUCTURES"
The Chair of Steel, Lightweight and Composite Structures also offers the seminar "TEKLA-STRUCTURES" for students in the master's degree course in civil engineering in cooperation with Trimble. The event will take place from July 23rd to 25th, 2019.
For further information please contact: Stefanie Röscher.
A short report on the event from last year can be found on the Trimble homepage.

June 2019 - Summer party at the Institute for Structural Engineering
The institute's employees celebrated the 250th college meeting of the Institute for Structural Engineering with a summer party. A relaxed afternoon with numerous rounds of discussions was spent in a relaxed atmosphere with cool drinks and a grill buffet.

June 2019 - VIII International Conference on Coupled Problems in Science and Engineering, Sitges, Spain
The "VIII. International Conference on Coupled Problems in Science and Engineering " took place from 03.-05. June 2019 in Sitges (Spain). This conference deals with numerical methods and computer-oriented procedures for solving complex problems of coupling in science and technology.
In the "Thermo Mechanical Problems" topic block, Faranak Faghihi successfully presented the results of her doctoral project "Advanced Implementation of Hybrid Fire Simulation" on the topic "A computational framework for thermal coupling in hybrid fire simulation".

January 2019 - guest lecture
We cordially invite you to a guest lecture as part of the course "Bridge Construction - Design, Construction and Design" on January 31, 2019 at 10:15 a.m.
Dr.-Ing. A. Wehnert-Brigdar and Ms. M.Sc. J. Feller from the Schüßler-Plan Ingenieurgesellschaft mbH from Dortmund will give exciting insights into practice with the lecture "Insight into the design of the Emschertal bridge - design of the steel truss bridge".

January 2019 - Low-cycle fatigue test on the notched beam
In January 2019, a 2.00 m long notched beam was successfully tested in the area of "low cycle fatigue". During the test, crack initiation and crack progress were documented on the rolled profile. The strain behavior in the notch area was recorded during the test by means of strain gauges. Two symmetrical cracks based on the predicted notches were observed.

September 2018 - Experimental testing on hollow profile composite columns
As part of the FOSTA research project "Concrete-filled hollow profile composite columns for multi-storey buildings - innovation and design" (IGF project no .: 19677), the stability behavior of hollow profile composite columns is investigated using experimental, numerical and analytical methods.
In April of 2019, a 4-meter-long double hollow profile composite column made of high-strength materials was successfully tested in the construction parts test (KIBKON). During the test, the force applied, the deflections in the quarter points and the head plate rotation were measured. With the help of strain gauges, elongations of the hollow profiles were recorded at selected points along the column axis. The column tests are intended to provide significant insight into the load-bearing capacity and deformation behavior of concrete-filled composite columns. Further column tests will follow in the coming months.

September 2018 - residual stress measurements on welded beams
As part of the research project "Bending twist buckling as buckling of the pressure belt", residual stress measurements were successfully carried out on 15 welded steel girders. The water jet cutting system newly acquired by the Institute for Structural Engineering (KIBKON) was used for the first time as part of a research project. Through the use of more precise and Comprehensive measurement technology and the new waterjet cutting system, this large-scale project was successfully carried out using the latest technology.

January 2018 - Blended Learning Method
Since the winter semester 2017/2018, teaching in the "Computational Engineering" event has been carried out using the new format of "blended learning". In "blended learning", students are offered a tailored online platform in Moodle with extensive learning materials and applications. This enables students to learn at their own pace and in their own chosen environment. The face-to-face events are held as an "inverted classroom", whereby students can review and present independently acquired knowledge.
