This article summarizes the results of an extensive experiment designed to determine the effect of geometric and mechanical parameters on the axial strength of the bonds formed when threaded steel bars are glued into sawn hardwood timber. The studies conducted to date on glued wood joints have focused primarily on softwood glued laminated timber or glulam. In the present study, specimens made from two hardwood species with very different physical and mechanical properties were used to evaluate the effect of wood characteristics on the axial strength of such bonds. Several geometries were tested by loading a total of 190 specimens to failure. The ultimate load values found for the specimens were compared to the design values proposed in the final draft version of Eurocode 5 (prEN 1995-1-1(2001)).
