The reception building in 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 steel structure consists of a total of 1,389 tubular steel members, each connected in 269 nodes.
A total of ~ 92.594 tons of steel were used for the project. The translucent roof, with a total surface area of approximately 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 "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
- Design of five types of seismic force-resisting systems (SFRS) includes Special Moment Frame (SMF), Intermediate Moment Frame (IMF), Ordinary Moment Frame (OMF), Ordinary Concentrically Braced Frame (OCBF), and Special Concentrically Braced Frame (SCBF)
- Ductility check of the width-to thickness ratios for webs and flanges
- Calculation of the required strength and stiffness for stability bracing of beams
- Calculation of the maximum spacing for stability bracing of beams
- Calculation of the required strength at hinge locations for stability bracing of beams
- Calculation of the column required strength with the option to neglect all bending moments, shear, and torsion for overstrength limit state
- Design check of column and brace slenderness ratios
The seismic design result is categorized into two sections: member requirements and connection requirements.
The "Seismic Requirements" include the Required Flexural Strength and the Required Shear Strength of the beam-to-column connection for moment frames. They are listed in the ‘Moment Frame Connection by Member’ tab. For braced frames, the Required Connection Tensile Strength and the Required Connection Compressive Strength of the brace are listed in the ‘Brace Connection by Member’ tab.
The program provides the performed design checks in tables. The design check details clearly display the formulas and references to the standard.
In the Concrete Design provides an option to perform seismic design according to AISC 341-16 for steel members.
Five SFRS types (Seismic Force-Resisting Systems) are available for this.
