Building Interface

The interface between the building and the traverse is an important factor for the final performance of the natural frequency of the traverse. Two factors are very important:
-  The stiffness of the building where the traverse is connected to the building.
-  The length of the free span of the main moving beam.

Traverse system at BMW Ascheim, Germany. X-Y-Z=9.7 x 7.5 x 2.7m. Max wind speed: 288 km/h. Natural frequency: 12 hz.
The stability of the traverse system is based on a high natural frequency of the traverse as well as a stiff support from the building. To achieve necessary support stiffness the building usually has to be reinforced.
