Column Substitution for Brandenburg Gate in Berlin, Germany
Customer Project
During the final days of World War II, a column segment of the Brandenburg Gate was severely damaged by grenade attacks. When the gate was reconstructed in 2002, the German engineering office of J. Sando in Weimar developed a method by which it was possible to substitute the column segment. The special supporting structure necessary for the substitution process was designed using RFEM.

Basic Technical Conditions
The structure load is transferred across masonry arcs into the columns. Lateral supporting is impossible without deconstruction. Engineer Sando has developed a method by which the load is redirected within the column. By constantly checking the force and displacement, it was possible to monitor the work steps at all times. Critical moments, of course, had to be excluded for this building.
Preparatory work for load increase was followed by mounting the hydraulic supporting structure step by step. The new center piece, which is exactly half of the column segment, was inserted after an intended vertical elongation of 0.2 inches. With both side parts, it is now clearly discernible as the new segment. The method chosen was a great success.

Parametrization of Rolled Cross-Sections
Rolled sections, the most common cross‑section type in RFEM and RSTAB, can also have user‑defined parameters.
- How do I apply wind load on members of open structures?
- I do not want to design a cross-section in the RF‑/STEEL EC3 add-on module. Can I quickly remove this cross-section from the selection?
- I have a roof structure resting on a steel column that runs to the foundations. The column runs through a perimeter wall that supports the false ceiling. A considerable part of the load from the roof is transferred to the wall. I want the steel column to carry all the vertical loads from the roof. How can I do it?
