Joints in Glulam using Groups of Epoxy Grouted Bars

Epoxy-grouted threaded steel dowels were used to make connections between 800 mm deep glulam members and fabricated steelwork in structures erected for the Olympics 2000 games in Sydney. This paper describes tests done to check the adequacy of these connections. The results show that the strengths of groups of bars may not simply be an integer multiple of the strengths observed on single bars. The results also show that with good timber selection and detailing the strength of the connection can be dramatically improved.
