Entrance Structure "Mitoseum" in the Dinosaur Park Kleinwelka, Germany
The entrance structure to the dinosaur park Kleinwelka 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.

A total of 84 tons of steel were used for the project. The translucent roof with an overall surface area around 24757 ft² consists of 463 ETFE foil cushions.
In addition to the entrance area, a souvenir shop, restrooms, adventure area as well as a gallery are also available in the building. Visitors also will 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 and at the same time eco-friendly lightweight steel and membrane construction.

SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.
