An optimized structure for the students of Campus Santé
The building consists of four wings and a central section, each functioning independently in terms of structural stability. In the wings, the seven-story reinforced concrete structure rests on prestressed frames at the ground floor, enabling a column-free basement. In the central section, all slabs are suspended from the roof, creating open spaces on the ground floor and basement for circulation areas. Forces are transferred from the ends of the tension rods via diagonals, which structure the spaces and triangular stairwells.
Horizontal stability is provided by façade elements. Along the length of the wings, two diagonals at the ground floor extend into the basement walls. At the ends of the wings, „Eiffel towers“ stabilize the building, corresponding to the moment diagram of a fixed-end element.
Through optimized spans, the slab thickness was reduced to 25 cm. Horizontal stabilization is achieved using diagonals integrated into the façade, avoiding the need for CO₂-intensive structural cores. Extensive optimizations and the structural concept reduce the required material quantities, thereby minimizing the building’s ecological footprint.
