Stiffness of scarf joints with dowels

Popis výsledku v původním jazyce

Repairs to historical timber structures include connecting existing beams and new beams. Older ways of making the connection need to be used to ensure authenticity of the beam. In most cases, e.g. floor structures, the second limit state – serviceability – is of decisive importance. The most widely-used joint is a scarf joint with two or more bolts or dowels. It is not clear whether greater obliquity of its cheeks is desirable, or the effect of different numbers of bolts on the stiffness of the beam. In Germany, a scarf joint with four bolts is recommended, but there is no validation for this from the structural perspective. In the process of repairing historically valuable timber structures, the most widely-used joint is with wooden dowels. A theoretical solution requires simplifications, and these are derived from experimental results. The results of numerical analysis are very encouraging. The final changes in the stiffness of repaired beams in comparison with the original beams are in very good agreement with experimental results.
