"Mitoseum" Entrance Structure in Kleinwelka Dinosaur Park, Germany
Customer Project
The entrance structure to Kleinwelka Dinosaur Park near Bautzen, Germany has a total height of 72 ft and resembles mitosis. Mitosis is a type of cell division and the origin of life. The bionic structure consists of 1,389 steel tube members assembled together at 269 joints.

Model
A total of 92.6 tons of steel were used for the project. The translucent roof, with an overall surface area around 24,757 ft², consists of 463 ETFE foil cushions.
In addition to the entrance area, a souvenir shop, restrooms, and adventure area, as well as a gallery, are available in the building. Visitors will also notice a colossal Spinosaurus welcoming them at the main entrance.
Stahlbau Hahner GmbH in Petersberg and rimpf Architektur in Hamburg received an award for the structure at "Deutscher Verzinkerpreis 2017" (3rd place, Architecture). The engineers of zapf & co. from Strausberg were responsible for the structural analysis of the steel structure, as well as the foil cushions. The spatial structure was analyzed in RSTAB and the cushions in Easy.
The "Mitoseum" is a spectacular yet eco-friendly lightweight steel and membrane construction.

Consideration of Construction Stages in RFEM 6
The calculation of complex structures by means of finite element analysis software is generally performed on the entire model. However, the construction of such structures is a process carried out in multiple stages where the final state of the building is achieved by combining the separate structural parts. To avoid errors in the calculation of overall models, the influence of the construction process must be considered. In RFEM 6, this is possible by using the Construction Stages Analysis (CSA) add-on.
New
Compared to the RF-/ALUMINUM add-on module (RFEM 5/RSTAB 8), the following new features have been added to the Aluminum Design add-on for RFEM 6/RSTAB 9:
- In addition to Eurocode 9, the US standard ADM 2020 is integrated
- Consideration of the stabilizing effect of purlins and sheets by rotational restraints and shear panels
- Graphical display of the results in the gross section
- Output of the used design check formulas (including a reference to the used equation from the standard)
- How do I perform stability analysis to determine the critical load factor in RFEM 6?
- How can I optimize cross-sections within the steel design?
- Why do the results in a modal analysis differ between the initial prestress and the surface load?
- Where can I find the materials for the corresponding National Annexes in RFEM 6 and RSTAB 9?
- How do I apply wind load on members of open structures?
- Is it also possible to use RF‑/TOWER Loading without the other TOWER add-on modules?
- Although I have modeled two identical structural systems, I obtain a different shape. Why?
- I do not want to design a cross-section in the RF‑/STEEL EC3 add-on module. Can I quickly remove this cross-section from the selection?
- I have a roof structure resting on a steel column that runs to the foundations. The column runs through a perimeter wall that supports the false ceiling. A considerable part of the load from the roof is transferred to the wall. I want the steel column to carry all the vertical loads from the roof. How can I do it?
- Are the models and presentations from Info Day 2018 freely available, and can you send them to me?
