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.
Since the building element 1 of the science park in Linz has now been completed, it will be described in detail here. The building is a framed structure consisting of reinforced concrete with a total length of approximately 492 ft and a variable width of 66 - 85 ft.
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 RF‑CONCRETE and EC2 for RFEM add‑on modules.
First, the building was modeled using the Rhinoceros design software. 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.
“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.” says Florian Stockert, engineer at Werkraum Wien.

Since wind on laterally open structures is not addressed in the Eurocode, the 4 cases of the German DIN 1055 Part 4 are referenced.
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
Which units are specified in the result display of the support reactions (kN or kN/m)? A note about this is missing in the graphic.
In the case that the support reactions are given in kN/m, for which distance does the value apply?
Is it possible to specify shrinkage effects as loads?
- Where do I find the setting to specify the entered structural component as a "wall" or "slab"?
- The four plates, identically loaded, show different negative moments at the point of support. Is this a mistake?
- How is the static depth d calculated in the bending design of block foundations (calculation as equivalent beams)?
- Is it possible to set parameters for shrinkage and creep calculation in RF-CONCRETE Members?
- I would like to convert the load from a surface load to a line load, that is, to apply it to the individual beams. How can I do this without using an auxiliary area?
- I have defined temperature loads, strain loads, or a precamber. As soon as I modify stiffnesses, the deformations are no longer plausible.
- Can the properties, such as B. the cross -section or the surface thickness as well as the material of a surface of an existing element for a new element?
- When should the punching load be determined with the (un)smoothed distribution of the shear forces at the critical perimeter?
