PSE Bielawa – The toughest steel detailing in my life
An elliptical dome made of up steel structural members, 17 metres wide, 36 metres long, 14 metres high. Twenty ribs converging along elliptical paths towards the top. The ribs formed the framework of the building. Each rib was different. Some of the ribs were basically slightly modified mirror images of each other. The ribs to one side of the building rested on the foundations and those to the other lay on structure of reinforced concrete five metres above. Each rib comprised two round tubes – top and bottom – bent to the correct shape. The ribs were wider at the base and tapered towards the top.
