New Elementary and High School Building in Laupheim, Germany

The new three-story building of an elementary and high school in Laupheim, Germany is made of reinforced concrete.

One of the special challenges of this project was that some of the stiffening shear walls could not be built to reach the foundation.

They designed a three-story building with the following maximum dimensions:

Length: ~ 190 ft | Width: ~ 183.7 ft | Height: ~ 52.4 ft
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 55.7 ft x 78.7 ft.

The German engineering office of 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. 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 were 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.”
