The reception building in Dinosaur Park Kleinwelka near Bautzen, Germany has a total height of 22 m (72 ft) and resembles mitosis. Mitosis is a type of cell division and the origin of life. The bionic steel structure consists of a total of 1,389 tubular steel members, each connected in 269 nodes.
A total of ~ 84 metric tons (92.594 US tons) of steel were used for the project. The translucent roof, with a total surface area of approximately 2,300 m² (24,757 ft²), was realized using 463 ETFE foil cushions.
In addition to the entrance area, a souvenir shop, restrooms, adventure area, and a gallery are available in the building. Visitors will also notice a colossal Spinosaurus welcoming them at the main entrance.
Stahlbau Hahner GmbH from Petersberg and rimpf Architektur from Hamburg were honored for the construction at the "Deutscher Verzinkerpreis 2017" (3rd prize in architecture). The engineers of zapf & co. from Strausberg, Germany were responsible for the structural analysis of the steel structure and 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.

In the Snow Load Wizard, you can optionally consider snow overhang and snow guard when generating snow loads according to Eurocode.

The Construction Stages Analysis (CSA) add-on allows you to modify the object and design properties of members, surfaces, and so on, in the individual construction stages.

During the calculation, you can display the model deformation for the calculation steps graphically in the calculation progress window.

In the wind simulation, it is possible to consider member coatings (for example, from ice loads).
Can I use Dlubal API in Rhino and Grasshopper?
In the Steel Joints add-on, I get high utilization ratios for preloaded bolts in the tension design. Where do these high utilization ratios come from and how can I evaluate the load-bearing reserves of the bolt?
Can I optimize parametric cross-sections?
How can I define RSECTION cross-sections in Grasshopper?
How can I fix the error warning “10060 - The structure is unstable” for modal analysis instability?
Is it always necessary to consider tension member nonlinearities in response spectrum analysis?
