DVW—Local Reinforcement for Timber Joints
Publication: Journal of Structural Engineering
Volume 127, Issue 8
Abstract
Joints are a matter of crucial importance in any major timber structure. They must have satisfactory strength and stiffness together with reasonable ductility and energy absorption, particularly if designed for use in seismic areas. In joints made with dowels, these requirements may more easily be met if the timber is reinforced locally in the area of the joints and use is made of a hollow cross section in place of a solid cross section for the dowel. Densified veneer wood (DVW) has been found to be a good reinforcing material because of its high embedding strength and its compatibility with timber. In this paper, results obtained from parametric studies made by means of the use of validated numerical models are presented to demonstrate the effectiveness of the DVW reinforcement. The study shows that, even with thin local reinforcement, joints perform significantly better than without it.
