How do you isolate an inner-city building from vibrations from the underground tunnel running underneath? The GuD planning team faced this complex challenge in the construction of a new commercial building in Berlin-Kreuzberg.
The new building at Ritterstraße 16-18 is supported by a steel grid so that the underground running underneath is not stressed. The bearing of the grating on the foundation elements, as well as the entire building foundation, had to be designed in such a way that the vibrations from the underground are not carried into the new building.
Based on structural dynamic FE models, GuD dimensioned the bearing on elastomer mats from Getzner. In the control measurements on the now almost completed building, the high effectiveness of the elastic building support could be proven. This means that nothing stands in the way of using the new building without disturbing influences from the underground traffic.
We are pleased to have been involved in this exciting engineering task and hope that the users will enjoy the new building!
