New School Building in Gol, Norway
In June 2016, a new modern school was opened in Gol, Norway, after almost two years of construction.The three-story building with a gross floor area of 8,500 m² provides space for 750 students from the 1st to the 10th grade.

Large glass surfaces provide good lighting conditions in the building all year round. The Norwegian company DBC AS, a customer of Dlubal Software, was responsible for the structural analysis of the school and the detailed planning of all in‑situ concrete constructions. In addition, DBC AS delivered the internal forces calculated in RFEM to the producer of prefabricated construction parts (concrete & steel).
The entire spatial model was entered and calculated in the structural FEA software RFEM. It consists of steel, reinforced concrete, and timber and includes 1,421 members and 193 surfaces.
The roof covering of the school is realized with Lett‑Tak elements (sandwich elements with integrated thin steel sections). These elements have very high load bearing capacity for vertical loads (span up to 18 m). However, they rather tend to be subjected to shear behaviour. In order to represent the roof panels correctly, the surface elements with appropriate stiffnesses (determined by the Lett-Tak company on the basis of tests) were modeled in RFEM.
Two lift shafts and transverse walls of prefabricated prestressed concrete elements together with the steel diagonals ensure the horizontal stiffening. For the diagonals and columns, pipes and square tubes were used for aesthetic reasons. Rigid frames were applied in the areas where it was not possible to arrange the bracing.
Data exchange between the structural engineer and the architect or other parties was carried out by IFC models. In this way, it was possible to perform the optimum collision checks. Moreover, this was very helpful to meet the very tight building schedule.

The construction industry is increasingly digitized. Structural engineers, a smaller group in the construction industry, are not always considered as engineers who immediately join the latest trends. Often for good reason.

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.
- When I apply an area load to a surface with an opening, the load is not not accounted for at the opening. Is it possible to automatically consider the area load as a line load around the opening perimeter?
- Is it also possible to determine stiffnesses of an existing column instead of a fixed nodal support?
- I just have to calculate an open hall with low roof loads and relatively high wind loads compared to it. In theory, a design of the bottom flange for buckling/toppling would have to be performed. Unfortunately, there is no combination of 1.0 * G +1.5 * W.
- How do I get the largest column load in my RFEM 3D model?
- Is it possible to design bidirectional ribbed plates, unidirectional ribbed plates, or hollow core slabs in RFEM?
- I get the message that my material does not meet the requirements of the current standard. How can I correct this?
- Why are the values of a column base, head or center on the individual columns only displayed partially for the results from the calculation in RF‑CONCRETE Columns?
- I am trying to manually check the deformations from the CRANEWAY add-on module. However, I obtain great deviations. How to explain the differences?
- What should be considered when using a failure of columns under tension in the RF‑/DYNAM Pro – Equivalent Loads add-on module?
- Why is there no stability analysis displayed in the results despite the activation of the stability analysis in RF‑/STEEL EC3?
