Abstract

In this study, steel-reinforced topology optimised beams were 3D printed through the layered extrusion technique and in combination with cementitious printable mortar. Cementitious material properties were used as input data of the topology optimisation algorithm to identify the optimised beam shape reducing the material used. The steel reinforcement was designed using small-diameter deformed bars (i.e., φ8) placed into the inter-layer plane during printing. Themain structural design features are discussed, along with the results of flexural tests carried out on a 2 m long beam with/without reinforcement tested in a 3-point bending configuration. First, the experimental results enabled the validation of the topology optimisation algorithm by comparing the experimental failure loads with the design ones. Secondly, the experimental outcomes allowed the comparison between the mechanical response of 3D printed beams with and without reinforcement, highlighting the significant role of the joints of the printing path.
