Innovations in the area of engineered wood products provide new possibilities for the design of timber bridges. Bonding high-strength fiber-reinforced plastic (FRP) composite plates to the tension face of wood beams can improve stiffnesses and strengths. By further incorporating a concrete compression flange, an even more versatile and efficient structural member can be created. The use of concrete-wood-FRP composite beams for timber bridges in investigated. The criteria involved in designing timber beams for bridges are presented. Then, details and results of an experimental study aimed at addressing design-related issues for concrete-wood-FRP composite beams are discussed. In the study, a series of wood, wood-FRP, concrete-wood, and concrete-wood-FRP composite beams were tested. The wood used was a laminated veneer lumber; the reinforcement consisted of carbon FRP plates. Composite action between the concrete flange and the wood web, bond strength between the FRP plates and the wood, and stiffness and ultimate strength properties of the composite beams were evaluated. Results of the tests indicate that composite wood beams show promise for use in timber bridges.
