- The wood construction industries are becoming more focused on climate change and resourcedepletion, and individual and industrial consumption must reflect a greater degree of concern for theclimate and environmental wellbeing. This paper presents a new concept for timber engineering, thepurpose being to acquire information about the failure modes and the tensile and compressivestrengths of two types of joint, the Simple Gooseneck and Thick Gooseneck, that can be used in anew concept for joining members in timber structures. This Makerjoint concept uses laminated veneerlumber (LVL) as nodes in regions with a pronounced non-uniform stress distribution and sawn timberin regions with a more uniform stress distribution. No metal fasteners or adhesives are used in thejoint between timber and LVL. The concept is intended for joints using 3-axis CNC machinery and tobe a system for on-site- and pre-fabrication of e.g. small houses, emergency shelters and exhibitionstands. The joints have a higher compressive than tensile strength. The joints exhibited brittle failure intension (beam and/or node failure) and buckling occurred in compression around the thinnest crosssection of the beams. Suggestions are made for how the mechanical properties of the joints can beimproved.
