Open-Air Theater Grandstand Roof Structure in Sömmersdorf, Germany
Customer Project
An impressive roof structure was constructed over the Passion Play open-air theater in Sömmersdorf, Franconia (Germany). The self-supporting spatial steel structure includes a PVC membrane roof covering the 14,908 ft² auditorium. Only four foundations in total support the entire roof structure.

Model
The valuable Dlubal customer Joachim Ingenieure was the design engineer for this fascinating project. The engineering office utilized RSTAB for the structural analysis.
Structure
The main structure includes two pairs of framework arched trusses inclined in opposite transverse directions. The trusses have a free span close to 148 ft. Twelve additional trusses span the main arched truss pairs in the longitudinal direction. They also cantilever 26 ft at the end locations. The total length of the roof structure amounts to 131 ft.
The arched trusses as well as the intermediate trusses consist almost exclusively of circular tube sections. The roof’s transverse stiffness is provided by the arched trusses, while the longitudinal stiffness is provided by the intermediate trusses as well as X-braces.
The four abutments, constructed at a 45° angle, are fixed to the ground with a reinforced concrete foundation including micropiles with varying angles. The micropiles for one abutment measure a total length of 433 ft.

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.

Application of Connections to the Structure | Steel Joints
- The proposed connection can be applied to all selected nodes in the structure
- The location of the connection can be defined using the "Main" tab of the Add-on dialog box
- The design is performed for all connections in the structure and after the calculation, the results on all connections can be displayed
- The table shows the results for the individual connections, each connection is designed and can be saved separately
