Innovations in glulam timber bridge design

Structural glued laminated timber has been successfully used as a bridge material in the United States for more than 50 years. Until the late 1980s, the majority of these bridges were conventional girder or deck superstructures manufactured from
softwood lumber species. Recently, applications employing glued laminated timber have been expanded to include alternative wood species and new designs utilizing the concept of stress-laminating. Additionally, current research on the composite materials using glulam may lead to future applications for timber bridges.
