Conversion of Gasometer into Event Space

The former gas storage facility has been transformed into an extraordinary event area using a completely new interior design. A steel construction of around 35 m (114.8 ft) with a diameter of 40 m (131.2 ft) has been built on top of an approximately 6 m (20 ft) high massive ground floor. Since the end of 2014, the 360° panoramas of the Berlin artist Asisi have been exhibited inside the building.

Structure

18 radially moving truss girders, which are connected by a compression ring at the ridge and a tension ring at the upper and lower chords, form the main structure of the roof. Pressure tubes and diagonals arranged around it form the roof panel.

The primary structure of the facade is made up of 18 bracket and facade supports, which are arranged in a grid of 10°. The stiffening of the cylinder is guaranteed by the arrangement of horizontal ring stiffeners in connection with compression and tensile-rigid diagonals.

To be able to determine the unevenly distributed wind load as realistically as possible, the entire main structure was modeled spatially with RFEM.
