Summary
The performance of structural members made of engineered-wood products such as glue-laminated timber (Glulam) is greatly influenced by the capacity of their connections. Outcomes of an experimental study undertaken to evaluate the strength and stiffness of steel-wood-steel glulam frame connections are analysed and presented in this paper...

Summary
The outcomes of an experimental study aimed to investigate the structural behaviour of wood-steel-wood glulam frame moment-resisting connections that were subjected to static bending are presented in this paper. Each frame test assembly was consisted of two glulam beams simply supported at their far ends and were connected to an inverselyloaded glulam column in the centre using two steel T-stub connectors. Two test variables including bolt’s end distance and number of bolt rows were investigated in eight full-size glulam beam-column assemblies. Test results revealed that increasing the number of bolt rows from two to three, with each row included two bolts, significantly increased the connection moment capacity with much greater increments compared to those added by increasing the bolt’s end distance from four- to five-times bolt diameter. However, brittle failure modes were found to be more pronounced in the connections with three rows compared to the connections with two rows of bolts.
