The link between the businessman Wolfgang Schweidtweiler from Pforzheim (Germany) and the panorama artist Yadegar Asisi made it possible that the 100-year-old gasometer threatened by demolition can now be used in such a spectacular way.
The former gas storage facility has been transformed to an extraordinary event area by a completely new interior design. A steel construction of around 35 m with a diameter of 40 m has been built on top of an approximately 6 m high massive ground floor. Since the end of 2014, the 360° panoramas of the Berlin artist Asisi have been exhibited inside the building.
18 radially moving truss girders which are connected together by a compression ring at the ridge and a tension ring at the upper and lower chord form the main structure of the roof. Pressure tubes and diagonals arranged around it form the roof panel.
The primary structure of the façade is made up of 18 bracket and façade 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 has been modeled spatially with RFEM.
