Calibration of design strength values of Wire and Arc Additive Manufacturing inclined bars and intersections

Although being studied only for few years, Wire and Arc Additive Manufacturing (WAAM) will become the predominant way of producing stainless-steel elements in a near-like future. The analysis and study of such elements has yet to be defined in a proper way, but the projects regarding this subject are innovating more and more thanks to the findings discovered by the latter. This thesis is focused on an initial stage on the analysis of mechanical and geometrical properties of such stainless-steel elements produced by MX3D laboratories in Amsterdam, and to perform a calibration of the design strength values by means of Annex D of Eurocode 0, which talks about the analysis of the semi-probabilistic safety factors, hence the definition of characteristic values. Moreover, after testing the stainless-steel specimens by means of strain gauges and after obtaining mechanical and geometrical properties, a statistical analysis of such properties and an evaluation of characteristic values is performed. After this, there is to execute the calibration of design strength values of WAAM inclined bars and intersections.
