ABSTRACT:

3D printing, or additive manufacturing (AM), is starting to be explored as a viable manufacturing technique in the construction industry. A 10 m span stainless steel pedestrian bridge is being built using Wire and Arc Additive Manufacturing (WAAM) and, upon completion, will be placed in the centre of Amsterdam, the Netherlands. Material tests and cross-section testing on circular hollow section (CHS) and square hollow section (SHS) columns have been undertaken to support this novel project. The unusual nature of the geometry and material properties has necessitated the use of advanced laser scanning and digital image correlation measurement techniques, along with Archimedes’ measurements and silicone casting. The material response has been observed to be anisotropic, with a lower Young’s modulus and material strength in certain orientations. The ultimate compressive capacities of the tested cross-sections have been observed to have a larger variation between repeat specimens than typically seen with conventionally produced elements, and the ultimate compressive capacities are generally overpredicted by current design methods.
