Advanced FRP-Wood Composites in Bridge Applications
This paper describes two technologies for reinforcing or strengthening timber bridges with Fiber-Reinforced Polymers (FRP). The first consists of reinforcing the tension side of glulam girders or decks with unidirectional FRP. This technology allows to significantly increase the flexural strength of girders, particularly when low-grade laminating stock is used. The second consists of post-tensioning stress-laminated timber decks with transverse Glass FRP (GFRP) 7-wire strands. The paper briefly describes three demonstration bridges constructed in Maine using different aspects of these technologies: (1) the Medway FRP-glulam girder bridge, (2) the Milbridge FRP-glulam deck vehicular pier and (3) the Milbridge GFRP stress-laminated deck.
