New Secondary School Building in Laupheim, Germany
To build a new grammar and secondary school in Laupheim, Germany, the city of Laupheim organized an architectural competition, which won the Herrmann + Bosch Architekten studio from Stuttgart.

They designed a three-story building having the following maximum dimensions:
Number of Nodes: 3,328 | Lines: 4,755 | Members: 122 | Surfaces: 1,339 | Openings: 96 | Materials: 3 | Cross‑Sections: 6
The building forms a ring with an inner courtyard of approximately 17 m x 24 m.
The German engineering office Rohmer GmbH, a long-term customer of Dlubal Software, was in charge of the structural planning.
The reinforced concrete structure was entered as a 3D model in RFEM to take into account the spatial co‑action of the stiffening wall and floor surfaces. In this way, the building stability could be sufficiently ensured.
One of the special challenges of this project was that some of the stiffening shear walls could not be built to reach the foundation. In addition, due to the inappropriate soil, a pile foundation was required.
The reinforced concrete surfaces and members have been additionally designed in the RF‑CONCRETE add‑on module.
Anton Rohmer, responsible for structural planning, says: “Under the given conditions, and due to the building geometry, only a 3D calculation could provide realistic and efficient results.”

Since wind on laterally open structures is not addressed in the Eurocode, the 4 cases of the German DIN 1055 Part 4 are referenced.
Required reinforcement for rib and axial force distribution, wall taking into account the construction stages
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
Which units are specified in the result display of the support reactions (kN or kN/m)? A note about this is missing in the graphic.
In the case that the support reactions are given in kN/m, for which distance does the value apply?
Is it possible to specify shrinkage effects as loads?
- Where do I find the setting to specify the entered structural component as a "wall" or "slab"?
- The four plates, identically loaded, show different negative moments at the point of support. Is this a mistake?
- How is the static depth d calculated in the bending design of block foundations (calculation as equivalent beams)?
- Is it possible to set parameters for shrinkage and creep calculation in RF-CONCRETE Members?
- I would like to convert the load from a surface load to a line load, that is, to apply it to the individual beams. How can I do this without using an auxiliary area?
- I have defined temperature loads, strain loads, or a precamber. As soon as I modify stiffnesses, the deformations are no longer plausible.
- Can the properties, such as B. the cross -section or the surface thickness as well as the material of a surface of an existing element for a new element?
- When should the punching load be determined with the (un)smoothed distribution of the shear forces at the critical perimeter?
