Nonlinear analysis of the load-bearing capacity of folded carbon reinforced concrete modules. Given the increasing demand for low-carbon construction; the shift from massive to thin-walled; highly efficient elements are becoming increasingly necessary. The origami-inspired folded carbon concrete shells are emerging as an alternative to traditional reinforced concrete structures for the development of economical and sustainable structures. However; the field currently lacks any well-established design and analysis methods that can reliably predict how folded shells will behave structurally when optimal variants; load-bearing capacity; stress redistribution; and failure mechanisms are considered. Based on this; two FEM modeling approaches to analyze folded waterbomb-patterned shells were implemented. In these approaches; the carbon reinforcement is modeled in both smeared and resolved forms; whereas a damage plasticity model is applied to the concrete. The testing of the demonstrator elements validates the results of these approaches; which complement the foundation for the design and analysis of folded origami shells. © 2024; Ernst und Sohn.
