Wörgl Zentrum Lenk in Wörgl, Austria
In autumn 2012, construction has started in Wörgl, Austria for an apartment complex that is, by request of the building owner, completely planned and designed as a BIM model including structural analysis, work planning, call for tenders, etc. For this purpose, software tools from the company bimm GmbH were used, by which architects, structural engineers, and building engineers can work together efficiently on a 3D model. RFEM and the Autodesk programs Revit Architecture and Revit Structure, to which Dlubal has a direct interface, served as the basic software for this project.

Modeling and AnalysisThe entire model has been entered in Revit. Input includes more than 1,000,000 structural components (including guard railing, etc.). All structural specifications and load cases have also been entered in Revit Structure.
Then, the structural model has been transferred to RFEM by means of the direct interface. The interface is bidirectional, which means that data transfer is performed in both directions. If some structural components are changed in RFEM, they can be exported easily to Revit and vice versa.
RFEM has been used to carry out structural calculations and analysis of the concrete structures. The RFEM add‑on modules RF‑CONCRETE and RF‑PUNCH have completed the calculation.
Further characteristics of the structural models are:
Materials: 11 | Surfaces: 362 | Cross-sections: 7 | Members: 75 | Weight: approx. 10 million t
Materials: 21 | Surfaces: 419 | Cross-sections: 14 | Members: 72 | Weight: approx. 11 million t | Length: 56.5 m | Width: 54.5 m | Height: 22.5 m

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?
