Abstract
This paper deals with the data-driven design and manufacturing process of stress-optimized concrete girders. Parametric design concepts are utilized to generate load-specific cross-section dimensions that can be varied along the longitudinal axis of a beam or girder. By integrating FEM- analysis into this process, each segment can be optimized with regards to its topology, including tendon guides that are integrated into the concrete structure. Beginning with an overview of the theoretical background of concrete 3D printing and the basics of its digital process chains, this text describes the manufacturing process of the components. Furthermore, the structural properties are compared with the predicted deflection and load-bearing behaviour. Concluding, the results are discussed in detail.
