Funke Media Office, Essen, Germany
The Funke Media Group, headquartered in Essen, Germany, initiated a new corporate headquarters construction project to accommodate around 1,000 employees at an important traffic junction in the city center. The three-building complex includes a total area of 398,265 ft² in addition to a 300-car parking garage.

For this award-winning architectural project, FCP was hired as the general contractor in a joint venture with AllesWirdGut Architektur. Construction began at the end of 2015, with completion in January 2019.
The Funke Media office includes an elongated double structure with a connecting bridge tunnel as well as a circular media tower with a supplementary steel structure and media façade. The buildings, with 6 to 7 aboveground stories, are designed as framed structures consisting of reinforced concrete flat slabs, columns, and shear walls in the access zones.
The unique architectural design elements are the V-shaped columns on the double structure ground floor. The SB3 quality V-shaped columns give the impression of a "floating" monolithic structure on this open story. For this design, the V-shaped columns intersect the building’s orthogonal support beams, which required massive steel components. Additionally, the columns’ reinforcement, their connections, and reaching concrete design strength class C50/60 were extremely complex challenges. To tackle this issue, the building company created a preliminary design of the V-shaped columns to determine potential issues (formwork, reinforcement installation, concrete compaction, etc.) and create a design plan for optimal results.
A shallow subway structure (tunnel and emergency exit) located under the building posed another technical challenge. A combined pile-raft foundation (KPP) was needed to meet the allowable soil pressure and more importantly, to minimize building settlement. To limit settlement, the 47 in diameter bored piles along the subway structure (soil covering only 3 ft from the lower edge of the floor slab) were extended to a rigid soil layer depth to serve as a "rigid abutment". Regular (nightly) survey control work in the subway tunnel monitored settlement calculations. To prevent vibration, measures were taken close to the emergency exit.
The foundation, as well as the complexity of the supporting structure, were particular challenges in both the planning and design phases. This required advanced engineering knowledge to minimize construction time and costs.

This article deals with rectilinear elements of which the cross-section is subjected to axial compressive force. The purpose of this article is to show how very many parameters defined in the Eurocodes for concrete column calculation are considered in the RFEM structural analysis software.
RF-CONCRETE NL Add-on Module for RFEM | Nonlinear reinforced concrete calculation for the serviceability limit state
- In RF‑CONCRETE Surfaces, I obtain a high amount of reinforcement in relation to a lever arm that is almost zero. How is such a small lever arm of internal forces created?
- When converting from the manual definition of reinforcement areas to the automatic arrangement of reinforcement according to Window 1.4, the result of the deformation calculation differs, although the basic reinforcement has not been modified. What is the reason for this change?
- Why do I get a discontinuous area in the distribution of internal forces? In the area of the supported line, the shear force VEd shows a jump, which does not seems to be plausible.
- Is it possible to perform design without an additional reinforcement in RF‑CONCRETE Surfaces?
- I obtain different results when comparing the deformation analysis in the RF‑CONCRETE add-on modules and another calculation program. What could be the reason for this?
- For the design, I can only select the surrounding reinforcement for a rectangular cross-section. Why?
- What does the "Crack formation in the first 28 days" option means?
- I have recently purchased RSTAB with the CONCRETE add-on module. Can I use it to perform the stability analysis of reinforced concrete columns?
- Why do RF‑CONCRETE Members or CONCRETE determine a significantly higher provided reinforcement than the required reinforcement?
- Why do I get Error No. 10203 for a result beam when performing design with RF‑CONCRETE Members?
