Abstract

A new beech and self-tapping screw composite dowel is proposed and studied, its performance being compared with that of beech dowels and self-tapping screws alone. The single shear performance of components connected by composite dowels was tested. Results show that the dowels are a good choice for components requiring high stiffness. Screws remain a good choice for components requiring excellent seismic performance. Combination group presents similar maximum load stiffness to those of composite dowels, but other ductility parameters are superior for composite dowels. The best connection mode was provided by two composite dowels. Based on connecting two points, structural elements with two composite dowels showed much better load bearing ability than when joined by two beech dowels or by two self-tapping screws separately. The structural element with two composite dowels not only presented better initial stiffness, but also exhibited a better ductility coefficient and less energy consumption. So, the composite dowels can be used for beam column connection, dowel laminated timber, and restoration or enhancement of ancient buildings.
