Forum Gold and Silver in Schwäbisch Gmünd, Germany
Customer Project
By the day the 2014 State Garden Show begins, the construction of a building with a spectacular facade will be complete in the German town of Schwäbisch Gmünd. The project of the local association for noble metals is supposed to emphasize the reputation of the "gold and silver" town.

Model
The following data refer to the facade construction.
Length: ~ 82 ft | Width: ~ 82 ft | Height: ~ 82 ft | Weight: ~ 61 t
Number of Nodes: 811 | Members: 1,276 | Materials: 2 | Cross-sections: 7
The house is intended to be used as a place for presentations and events which are associated with matters of gold and silver as well as design.
The design of the building was commissioned by the German planning office isin architekten after winning the design competition. The German engineering office Klöckner carried out the structural calculation of the facade's supporting structure using RSTAB. They used RFEM for the facade cassettes. In connection with a wind report created by the German I.F.I. Institute for Industrial Aerodynamics, the wind loads to be applied were determined with a model put in a wind tunnel.
Facade Structure
The facade envelops the building like a coat made of gold leaf. But in reality, the approximately 800 facade plates of 4.9 ft x 4.9 ft consist of an aluminum alloy that is coated on both sides with DURAFLON®, a FEVE stove enamel finish for facades.
The steel supporting structure of the facade consists of 1,276 members altogether, with steel grades of S 235 and S 355. It is fixed to the building at 80 points. Ten round pipe columns of d=6.2 inches bear the majority of the vertical loads.
The RSTAB add-on module STEEL EC3 was used for the calculation. The facade cassettes with a thickness of 0.11 inches were calculated using the RFEM modules RF‑IMP, RF‑STABILITY, and RF‑STEEL Surfaces.
The cassettes are stiffened in the field by aluminum edge profiles. These were designed in RF‑ALUMINUM.

Evaluating and Documenting Steel Joints Analysis Results in RFEM 6
With the RFEM 6 add-on Steel Joints, you can analyze steel connections by using an FE model. This article demonstrates how to evaluate and document the steel joints analysis results.
New
- The design of the connection components is performed according to Eurocode EN 1993-1-8
- After activating the Add-on, the design situations for Steel Connections must be activated in the "Load cases and Combinations" dialog box
- For the design of the connection stability (Buckling), it is necessary to have the Add-on Structure Stability activated
- The calculation can be started via the table or via the icon in the top bar

How do I set a release for warping?
- How can I define a warping spring or a warping restraint?
- At which point on a cross-section are the supports and loads assumed for the calculation with warping torsion?
- The limit stress is activated, but my stress ratio is “non-designable” in the Stress-Strain Analysis add-on. What could be the reason?
- How can I deactivate the 7th degree of freedom for certain members or cross-sections only?

How can I display the cross-section warping?
- How do I define effective lengths when designing steel members in RFEM 6?
- How do I define a member as a cantilever and not as supported at both ends for serviceability or deflection design?
