19 Nemetschek Engineering User Contest 2009 • Category 1: CAE Constructive Elements 1 which have an outside sunblind, silver coloured and perforated, on the offices levels. The ground floor façade is vertical, from the first floor up the façade is sloping from 93 degrees, 1 degree per floor, up to 96 degrees. In front of the main façade a steel structure, connected to the façade and floors with steel walkways, is built, which kind off wraps the building up. To the outside of the steel structure, triangular shaped glass panes are connected with spider profiles. So the façade is a multilayered structure, where the exterior skin is a decorative structure wrapping the functionally different internal layers into one homogenous building appearance. The geometrical system composed of triangular elements makes the outlook of the building’s façade unique, modern and fresh. This structure is constructed from steel pipes of varying cross section climbing around the building in a triangular shape covered with clear glass. A three storey high internal atrium, starting from the 2nd floor, enhances the exclusivity of the building. This prestigious project is an example of public-private partnership between the Hungarian Foundation for Art and Free Education and ING Real Estate. Because of the different curves in the structure, it was necessary to calculate the structure as a 3D structure. In order to obtain the curved structure, we imported a 3D wire model from Autocad into Scia Engineer. The Nemetschek Scia programs were extremely useful, having the possibility of import and 3D calculation. The internal forces and reactions obtained from Scia Engineer were used to calculate the connections (steel-steel and steel-concrete). Vörösmarty Tér 1, multifunctional building, Budapest
