Modular systems of semi-finished folded components | Funding Period 2
In project C04, a novel construction approach for thin-walled carbon-reinforced concrete (CRC) elements made of modular folded components is developed. By leveraging origami principles and the foldability of the textile reinforcement, the project aims to create adaptable, high-performance, and resource-efficient CRC elements. To achieve this, a design principle based on waterbomb origami patterns, and a novel fold, plug, and lock concept is developed enabling flexible and resource-efficient production. Analytical and numerical models for module folding kinematics, fabrication, assembly, and structural performance will be developed and validated, with material-efficiency integrated into design and performance assessment. This will allow bridging the gap between material utilization, geometrical design and fabrication processes of CRC components.

Stability and Quasi-Ductility of Carbon Reinforced Concrete Structural Members | Funding Period 1
The central question in this project is how to achieve structural behavior with high stiffness in the service condition and, at the same time, a sufficiently large deformation capacity prior to failure using carbon-reinforced concrete, a composite consisting of solely brittle material components.
Due to the brittle behavior of carbon reinforcement, other sources of the stress redistribution need to be exploited in order to achieve the required ductility. During the loading, carbon-reinforced concrete exhibits local deterioration mechanisms such as debonding and the development of finely distributed cracks along the length of an element. The stress redistribution mechanisms occur especially in tensile zones and are accompanied with stiffness reduction. Methods exploting these mechanisms in the design of spatial thin-walled structures with ductile structural behavior are investigated in Aachen. The long term goal of the numerical and experimental research is to exploit the synergetic potential between form and material behaviour available in folded carbon-reinforced concrete shells.
At TU Dresden, the focus is on stability phenomena during normal force loading of filigree carbon-reinforced concrete components.
