The science park completes the Johannes Kepler University Linz in Austria by five further buildings.
In April 2005, an urban development competition was announced. Architects from Caramel in Vienna tendered and they won the contest. Engineers from Werkraum Wien using Dlubal Software programs were in charge of performing the structural analysis for all five building elements.
The building element 1 of the science park in Linz is a framed structure consisting of reinforced concrete with a total length of approximately 150 m and a variable width of 20-26 m.
The construction is made up of a deep basement, used as parking garage, and a first floor with laboratories. Above five upper floors are set up providing space for offices.
Flat slabs made of reinforced concrete represent the floor plates. The columns are prefabricated columns consisting of spun concrete. The entire structural system is stiffened by four reinforced concrete cores.
What is especially noteworthy is that the first floor has no columns in some of the floor areas. A specific arrangement of hanging steel trusses makes it possible.
The design of the spatial framework was carried out by the Dlubal Software program RFEM in accordance with Eurocode 2 and the National Annex for Austria (ÖNORM). Furthermore, the structure was analyzed in the add‑on modules RF‑CONCRETE and EC2 for RFEM.
First, the building was modeled using the design software Rhinoceros. Then, the data was imported to RFEM via DXF interface and the supporting structure was created. Finally, after applying the loads, the structural system was calculated.
Florian Stockert, engineer at Werkraum Wien, says: “Using 3D FEA program by Dlubal Software was a great advantage. Adjustments to the structure could be entered quickly and effects of structural modifications were immediately displayed.”
