Jointing Principles in AMC—Part 1: Design and Preparation of Dry Joints

The study described in this contribution contains a fundamental strategy to select geometries for dry joint profiles 3D-printed concrete constructions. A database, here called the ‘joint catalogue’, variety of types adapted from timber, steel, and bionic connections. Weighting factors different criteria evaluate score various (e.g., manufacturability, duration manufacturing, mechanical behaviour). Therefore, an algorithm sums up scores leading preselection better suitable profiles. preselected were afterwards analysed by finite element method, determining load capacity unit specimen. According catalogue, smooth, triangular, truncated cone arc profile appeared be optimal combination joints additive manufacturing construction (AMC).
