This diploma project is a design project of a 12-storey exhibition and office building in a steel structure. There are 5 exhibition floors with a height of 5.0 m each, 7 office floors each 3.8 m high, and technical floors with a height of 3.8 m allowing to go to the roof. The building is designed on a circular plan with a diameter of 30.0 m and a height of 55.4 m. The columns can be divided into inner core forming 11.0 m diameter and the outer perimeter of the object. Inside and outside columns are connected on each floor by radial beams. The elevation is suspended on the outer perimeter beams hinged between the outer columns.
The internal columns are rigidly connected to each other by internal circumferential beams. For stiffening of the structure, it is planned to place in the core a grid of rigidly connected beams on each floor. In order to provide small horizontal displacements, the "X" braces were placed in every second external field. The challenge was to determine the dynamic impact of the height of the building and to achieve appropriate rigidity while maintaining the lightness of the structure.
Special challenges
The challenge was to determine the dynamic impact of the height of the building and to achieve a more rigid construction while keeping the structure light. The challenge was also to design interesting connections at each level.
What made the project successful
The diploma dissertation was a success. This was decided by the design atypical structure.
