Abstract

Via the consultation of topology optimisation, this Study aims at finding weight optimised, externally reinforced concrete structures. The found organic geometries are realised using extrusion-based 3D concrete printing. Significant interactions between the complex girder geometry and the constraints of the manufacturing system are identified. This outlined first trail run of the entire process from preliminary design to nonlinear numerical evaluation as well as experimental testing in the course of full scale 1 : 1 Shear force tests of optimised, extemally reinforced concrete girders shows the basic feasibility of the presented process. The paper is concluded With the illustration of a future envisioned optimisation approach.
