Analytical Study on 3D-Printed Concrete Wall with Different Wall Configurations When Exposed to High Temperature

As 3D-printed concrete is more time efficient and environmentally friendly than conventional concrete, its development has accelerated over the past couple of years. The concrete is poured layer by layer in this system until the required dimensions are achieved. As studies related to 3D-printed concrete are limited, it is imperative to study its fire performance. In this research, using Finite Element Analysis (FEM) software, 3D-printed concrete walls with different openings have been analyzed to find the most effective wall configuration against high temperatures under the loaded condition. The results would show the most optimal wall opening when the load bearing 3D-printed concrete (3DPC) walls are exposed to high temperatures. In this study, 16 different models were analyzed and studied. It was found that the solid wall with no opening showed superior results against temperature when compared to the other walls, and the BR1 wall with a rectangular opening showed better results when compared to the other walls with openings. The displacement and stresses of each of the 3D-printed concrete wall models were also obtained.
