Finite Element Modelling for 3D Concrete Printing: Framework and Examples

Popis výsledku v původním jazyce

This study describes a novel numerical approach for simulating the structural behaviour of 3D concrete printed elements. It assesses the structural integrity both during printing at an early age and in the final mature state. The presented approach adopts the finite element method with a nonlinear material model for realistic material response. The hardening of the printed paste is captured by progressively adjusting the material model parameters during the step-by-step solution. The 3D printing and load capacity assessment are analysed within a single analysis, thus the deformation occurring during printing affects the predicted load-bearing capacity. Additionally, the approach utilizes interface elements to simulate potentially weaker connections between the printed layers. The simulation framework is illustrated in two examples: a comprehensive 3D printing and loadbearing capacity analysis of a simple wall segment and a 3D concrete printing simulation of a singlestory house structure.
