New building materials like carbon reinforcement and ultra-high performance concrete exhibit a high potential to build very thin-walled building components, but they require new production and connection technologies. For example, introducing high loads into the thin structural members leads to local peak stresses. Steel implants, designed by use of structural and topological optimization in collaboration with Professor Werner Sobek, who leads the Institute for Lightweight Structures and Conceptual Design (ILEK) at the University of Stuttgart, can reduce these stresses and increase the utilization factor of the materials. In addition, a simplification of the connection technology of the concrete elements goes along with the use of these implants.

In general, structurally optimized building components produce very resource efficient and geometrically complex structures. Within our research, we investigate the use of new production technologies like 3D printing to simplify their manufacturing.
