Abstract

Digital 3D printing is a new way of constructing concrete and reinforced concrete structures. This paper introduces an integrated approach that combines a time-dependent material model for curing concrete with a finite element method (FEM) nonlinear solver. This solver progressively activates finite elements along the printing path. The material behaviour model is directly based on the hydration mechanism. Additionally, interface elements with time-dependent material properties are inserted between layers to account for the weaker mechanical properties of layer connections. A case study demonstrating the layer-by-layer construction of a structure is presented to validate this framework.
