Description
The idea of the architects (grupa 5) was to design a light roof, which would not violate the beauty of the historic Art Nouveau architecture. The new roof was designed as a membrane structure, tensioned on steel arches, which covers the area of four platforms between two old sheds. The structure of the membrane roof consists of 12 similar fields. The dimensions of a singular field are 21x11.40m. The total dimensions of the membrane roof are 84x34.2m. The main bearings elements are longitudinal, perpendicular and diagonal arches made out of tubes with a diameter of 356mm. The shape of the arches refers to the original arches of the German architect Bernard Klusch, built in the years 1899-1904. In the dome surface of the roof, bracing are applied. The roof is situated in a first snow zone, thus total snow load is 1.05kN/m2. According to the requirements of the Polish law concerning snow removal, in the low points of the membrane on the columns, huge openings were introduced. The membrane is attached to the main longitudinal arches on the bottom side. In this way the steel structure (arches and bracings) is visible from the platform only on sunny days as a shadow on the membrane. The use of the translucent membrane (Mehler Mehatop F IV) gives a lot of light to the platforms and brings a friendly and pleasant atmosphere.
