Enhancing Structural Efficiency In 3D Printed Concrete Beams Through Truss Topology And Barbed Wire Reinforcement

Abstract

3D printing, or additive manufacturing, revolutionizes the transformation of digital geometric representations into tangible objects through extrusion. This innovative technology has various applications, such as cost reduction in construction, time savings, reduced reliance on manual labour improved construction safety, and enhanced environmental sustainability. However, a key challenge in adopting 3D concrete printing lies in reinforcing printed components to meet structural standards under varying loads. This study proposes an inventive solution by replacing conventional 3D printed beams with truss topology beams, reinforced using high-tensile barbed wires. This approach not only reduces material consumption but also strengthens hollow truss topology beams, utilizing galvanized steel barbed wires with superior tensile strength. The ANSYS software facilitates modelling and analysis, determining the optimal number of barbed wires for enhanced strength. The paper concludes with a comparative analysis of conventional 3D printed concrete and barbed wire-reinforced truss topology beams based on ultimate load-carrying capacity.
