| Summary: | The revival of timber framing in recent years and the development of computer
numerically controlled (CNC) machines have led to a number of research projects and
related studies on traditional timber joinery. This paper examines the experimental
evaluation of the structural performance of rounded dovetail connections. The study
investigates four different climatic conditions to evaluate their influence on the load
carrying capacity, stiffness, and failure modes o f single and double dovetail joints under
static shear loading. The study also examines the effect of manufacturing tolerances such
as machining speed and joint tightness (tight joint versus loose joint) on the overall
performance of the dovetail joints. It was found that the specimens manufactured and
tested in the dry condition outperformed the specimens evaluated under the other climatic
conditions. In the study of different manufacturing tolerances, it was determined that the
joints produced at low speed and without a gap had a higher capacity than those produced
at higher speed and with a gap. === Forestry, Faculty of === Graduate
