Model Data of Primary Two-Storey Structure

The school building addition in Sutz-Lattrigen was built on the existing ground floor. This foundation was not designed to withstand a second storey. Therefore, the loads from the first floor and the additional second storey had to be designed as concentrated loads. In order to reduce weight but also for educational and sustainability reasons, timber was used in the construction of the new building.

Indermühle Bauingenieure from the Swiss town of Thun was responsible for the timber engineering during the project phase including from the preliminary project to the supervision of the final design. The firm also completed the 3D project planning on behalf of the timber construction company. RFEM was utilized for the structural analysis. 

Structure

The additional floor consists of floor-to-ceiling trusses in the longitudinal and transverse directions. The truss diagonals are glued-laminated timber while the chords are steel. The chords are integrated in the timber-concrete composite floors.

The diagonals are connected with dowels and internal steel plates. The first floor cantilevers 3 m in the longitudinal direction and 4 m in the transverse direction over the first floor.

The visible timber structure as well as the glazed exterior and interior walls create an intimate, open atmosphere.
