Glulam rivets in radiata pine

Abstract

Glulam rivets are special nails for making high strength connections in timber structures. This paper describes an investigation of glulam rivet behaviour in radiata pine timber grown in New Zealand. Test results are compared with those on Canadian species, and with several international codes. The European yield theory is shown to give excellent prediction of glulam rivet strength in those connections where wood tension failures do not occur. Simple techniques for obtaining rivet bending strength and wood embedment strength are described, to provide input to the yield theory equations. Key words: fastenings, glulam, laminated, nails, pine, radiata, rivets, timber, wood.
